What is AI proposal software?
AI proposal software is a category of tools that use artificial intelligence to automate the creation of business proposals, RFP responses, and bid documents. These tools analyze your past proposals, learn your company's voice, and generate tailored responses in minutes instead of days.
As of July 2026, there are 17+ dedicated AI proposal platforms on the market, with pricing ranging from $49/month to $2,000+/month. The best ones learn from your past proposals, understand your unique value propositions, and generate customized responses without rebuilding a content library from scratch.
Traditional proposal software focuses on templates and content libraries. Modern AI-powered tools go further: they write original content, suggest relevant case studies, and check compliance against RFP requirements automatically.
AI-first vs. AI-added
Built around AI from day one. Tools like Bidara, AutoRFP.ai, and AutogenAI learn from your existing documents and start generating immediately. Same-day setup. Pricing typically published.
Legacy platforms (Loopio, Responsive, Qvidian) that bolted on AI features later. Still require weeks of content library setup before AI becomes useful. Sales-led pricing.
How we evaluated.
We tested each platform with the same real-world federal RFP to keep the comparison fair. Four metrics, each chosen because it directly affects your bottom line.
Setup time
How long from signup to your first usable proposal? We measured actual onboarding, including content library creation where required.
AI content quality
Does the AI generate original, on-brand content or generic fill-in-the-blank text? Scored for specificity, accuracy, and brand-voice consistency.
Time savings
Hours saved vs. manual creation. APMP reports the average RFP response takes 25 hours. We measured how much each tool actually reduces that.
Price transparency
Published pricing vs. “contact us” gates, hidden setup fees, forced annual contracts, and per-user surcharges. We reward vendors who publish.
Pricing verified from vendor websites, Vendr procurement records, and G2 listings as of July 2026. Where pricing is not public, we note the latest available information.
What testing 20 tools actually revealed.
Five data points that shape every decision in this category. Each one comes from hands-on evaluation, not vendor marketing.
Only Bidara, Proposify, PandaDoc, RFP360, AutoRFP.ai and DeepRFP post a real starting price on their own site. 10 publish no number at all, and 3 are third-party estimates rather than vendor figures. Range across the category: $49/mo to $2,000+/mo.
Loopio, Responsive, Qvidian require weeks of content library building before AI is useful. AI-first tools (Bidara, Tribble) are same-day.
Bidara, Inventive AI, AutogenAI, AutoRFP.ai, Tribble and DeepRFP. The other 14 gate evaluation behind a sales conversation.
Bidara, Inventive AI, AutogenAI and AutoRFP.ai verifiably train on your past proposals. Others offer tone controls, not adaptive learning.
Up from 42% in 2023, per the APMP 2024 Benchmarking Survey. The question for buyers in 2026 isn't whether to use AI, but which tool fits your team's pipeline composition and budget.
Who trains AI on your proposals?
Before you upload anything, one question matters more than any feature: what happens to the pricing, staffing plans and win themes inside your past proposals. We read the security pages of 16 of these 20 tools and looked for a direct statement.
Certifications do not answer this question. The 5 most heavily certified platforms here, each carrying 4 or more, all publish no position on AI training. Several tools with a single certification state one plainly. Read both columns; neither substitutes for the other.
| Tool | Trains AI on your content? | Certifications listed |
|---|---|---|
| Bidara | States it does not | 2: GDPR Ready, CCPA Compliant |
| Loopio | Publishes no stance | 6: SOC 2 Type II, ISO 27001, ISO 42001, CSA STAR, GDPR, CCPA |
| Responsive (RFPIO) | Publishes no stance | 7: SOC 2, ISO 27001, ISO 27701, ISO 42001, CSA STAR Level 1, GDPR, CCPA |
| Inventive AI | States it does not | 1: SOC 2 Type II |

| PandaDoc | Publishes no stance | 8: SOC 2 Type II, HIPAA, GDPR, FIPS 140-3, eIDAS, CCPA, FERPA, PCI-DSS |
| Ombud | Publishes no stance Cites ISO 27001 and PCI DSS certification of the facilities hosting its servers, not certification of Ombud itself. No statement about AI training. | None listed |
| AutogenAI | Publishes no stance | 6: FedRAMP High, ISO 27001, SOC 2, GDPR, NIST RMF, TX-RAMP |
| AutoRFP.ai | States it does not | 2: ISO 27001:2022, SOC 2 Type II |

| Conveyor | Publishes no stance | 1: SOC 2 Type II |
| SteerLab | Publishes no stance | None listed |
| DeepRFP | States it does not | 1: SOC 2 |
| Arphie | Publishes no stance Publishes zero-data-retention agreements with OpenAI and Anthropic, which limits what model providers keep, but no statement about training. | 1: SOC 2 Type 2 |
“Your content is never used for general AI training. Explicit opt-in required for any training.”
“Inventive AI does not use any customer data whether obtained through Google Workspace APIs or provided by users through any other channel to train, fine-tune, or otherwise improve generalized or non-personalized AI and/or ML models.”
“Your data is never used to train AI models. Working with AWS, GCP and Azure, your content stays confidential.”
“Your data never trains shared models. Customer content is protected and excluded from model training.”
“It is never used to train public models. Your content, client data, and IP stay protected.”
“Customer data is never used for model training or testing. All AI outputs are generated from models trained solely on public, non-sensitive federal data sources.”
“We never train any AI model on your data. Files stay encrypted, auto-purged after abuse checks, and we run on SOC 2-compliant US clouds.”
“Publishes no stance” means we could not find a statement on the vendor's own security pages as of July 2026. It does not mean the vendor trains on customer data, and you should ask them directly. 4 of the 20 tools here have not been checked yet; we are working through them and will publish each as it is verified. Bidara is our product, and our policy is linked alongside everyone else's.
The sticker price is not the price.
This category bills 4 incompatible ways: per seat, per project, flat, and by usage. Putting those headline numbers next to each other, which is what every comparison including ours used to do, tells you almost nothing.
Here is the same question asked properly. A five-person team, one month, using only prices published by each vendor.
| Tool | 5 seats, per month | How it meters | Working |
|---|---|---|---|
| Nusii | $49/mo | flat | Agency plan, flat |
| Better Proposals | $65/mo | per-seat | $13 x 5 seats |
| GetAccept | $245/mo | per-seat | $49 x 5, Professional |
| Qwilr | $275/mo | per-seat | $55 x 5, Growth tier |
| Bidara | $299/mo | flat | Starter, flat |
| DeepRFP | $445/mo | per-seat | $89 x 5 |
| AutoRFP.ai | $899/mo | per-project | Unlimited users |
Two things this changes. A per-seat tool that looks cheap stops being cheap fast: DeepRFP at $89 a seat is the lowest published per-seat price in the category and still costs more than a flat plan once you pass three people. And flat pricing only wins if the volume cap fits, so check that before the headline. Bidara is our product and is in the table on the same basis as everyone else. Prices are the vendors' own published rates as of July 2026; tools without public pricing cannot appear here at all, which is itself the answer to how they compare.
Is any of this free?
Not really, and anyone telling you otherwise is selling something. There is no free RFP response platform. What exists is one free tier, and 6 tools that let you evaluate without a sales call.
Conveyor. Focused on security questionnaires rather than full proposals, so it is free for a narrower job than most people arrive looking for.
Bidara, Inventive AI, AutogenAI, AutoRFP.ai, Tribble and DeepRFP. The other 14 require a sales conversation before you can see the product work on your own documents.
A free tier and a free trial are not the same thing, and this page counts them separately. A permanent free tier is a product you can keep using; a trial is a window. Conflating them is how “free” ends up meaning nothing.
The complaint and the compliment, side by side.
Every tool below gets one positive and one critical quote, taken word for word from independent reviewers. Showing only the criticism would be a hatchet job and showing only the praise would be useless, so the page will not build with just one of the two.
Loopio
4.6 from 74 reviews on Capterra“Loopio is an intuitive platform for content management and delegating responsibilities for various projects.”
Krunal P., Cybersecurity Analyst, IT and Services (10,001+ emp.)
“The import function can be clunky at times. When uploading a PDF I sometimes see formatting issues.”
Lisa S., Business Development, Information Services (51-200 emp.)
Responsive (RFPIO)
4.5 from 190 reviews on Capterra“Responsive makes this easier by providing a central repository for all RFP responses and enabling collaboration among team members.”
Hector T., Sr. Director Presales CoE, Computer Software (201-500 emp.)
“I wish I could Control + F my way through the app so that I could go back to previously mentioned answers and copy paste them.”
Sofia A., Proposal Writer, IT and Services (1,001-5,000 emp.)
Proposify
4.4 from 299 reviews on Capterra“Proposify was extremely easy to use. I used it primarily for business proposals and the flexibility that it offered in terms of placing graphics within text boxes made the job simple and effective.”
John B., VP Sales, Construction (11-50 emp.)
“Its clunky, difficult to use and when I used it wasn't properly integrated with Salesforce for ease.”
Jamie G., Senior Account Manager, Business Supplies and Equipment (11-50 emp.)
PandaDoc
4.5 from 1,255 reviews on Capterra“With the tool, I can easily create contracts and proposals that are consistent with our company's image.”
Atour T., Analyst (51-200 emp.)
“Sometimes, the platform can feel slow, especially when handling larger documents.”
Pathan I., Project and Program Consultant (10,001+ emp.)
Bidara is not in this table, because we have no independent review corpus yet and inventing one is exactly what this page exists to call out. What we do have is one direct quote from a trial user, shared with permission, which is a weaker form of evidence than a public review and is labelled as such. When real reviews exist they will appear here on the same terms as everyone else, complaint included.
Three questions, then a shortlist.
Most of the 20 tools here are wrong for you, and which ones depends on three things. No email required, and the answer changes as you click.

30-minute walkthrough with live AI generation. Trial access starts after the demo.
All 20 tools, in depth.
The best AI proposal software in 2026 is Bidara for small and mid-market teams (1–500 employees), Loopio for enterprise teams needing deep content libraries, and GovDash for federal contractors with FedRAMP requirements. Below: detailed reviews ranked by overall value.
1. Bidara: Best Overall AI Proposal Software
Book a DemoAI-first platform | Founded 2025
Pricing
Starter: $299/month (10 proposals/mo, 3 users). Growth: $599/month (30 proposals/mo, 10 users). Enterprise: custom. All plans billed annually. Full pricing details.
Best For
Small and mid-market teams (1-500 employees) responding to RFPs across government, consulting, engineering, healthcare, and professional services.
Key Features
- ✓AI that writes in your voice: Generates original, submission-ready content grounded in your past proposals, methodologies, and company data. Not generic templates with your name swapped in.
- ✓RFP-aware generation: AI reads the full RFP, extracts requirements and evaluation criteria, then tailors every section to what evaluators are actually scoring.
- ✓30-minute first drafts: Complete RFP responses in 30 minutes vs. the industry average of 25 hours. Upload your company documents, then upload the solicitation, and start generating the same day.
- ✓Deep knowledge base: 200 documents on Starter, 1,000 on Growth, unlimited on Enterprise. AI automatically references your past projects, certifications, and key personnel in every response, so nothing gets left out.
- ✓Nothing gets missed: Bidara pulls every requirement out of the solicitation into one list you review and approve. That approved list is what the draft is built from, so a requirement cannot quietly go unanswered.
- ✓No setup tax: Most competitors require weeks of content library building before AI works. Bidara learns from your existing documents on upload. You get value on day one.
Pros & Cons
Pros:
- + Output quality: AI drafts grounded in your real data, not generic filler
- + Same-day results, no weeks of content library setup
- + Transparent, published pricing
- + 5-day free trial, no credit card required
- + Works across all industries and RFP types
Cons:
- - Newer platform (founded 2025), though this means no legacy baggage and faster iteration
- - Fewer third-party integrations than enterprise tools
- - Annual billing only
Direct feedback, not a public review
“I'm a fan of the AI native construction and strategist design behind your product. We tried so many internal approaches and they just don't work well so I'm very hopeful and excited!”
Luis A., Co-Founder & Chief Strategist, Conekt2 (Small-Business, 50 or fewer emp.)
Bottom line: Bidara is built for teams that care about proposal quality, not just speed. Our AI reads the RFP, writes in your voice, and grounds every response in your actual company data. You also skip the weeks of content library setup that legacy tools require, so you can start winning this month.
2. Loopio: Best for Enterprise Teams
AI-added platform | Founded 2014 | G2: 4.7/5 (770+ reviews)

- - Content library setup required before AI is useful
- - Steep learning curve for smaller teams
4. Inventive AI: AI-First Challenger
AI-first platform | Founded 2023 | See our Bidara vs. Inventive AI comparison
Inventive AI is a newer entrant that, like Bidara, was built AI-first. It focuses on automating RFP responses using large language models and has gained traction among tech companies and startups. Pricing is not publicly listed.

Feature comparison.
The most important features to compare in AI proposal software are: AI content generation quality, voice/style learning, setup speed, compliance matrix automation, security questionnaire support, and pricing transparency. Only 6 of 20 tools publish a starting price, and only 4 verifiably learn your writing style.
This matrix shows which features each platform supports, based on our testing and vendor documentation. Where we could not verify a feature, we mark it with ~ (partial/unverified) rather than making assumptions.

Why ChatGPT and Claude aren't enough.
A common question we hear: “Can I just use ChatGPT or Claude to write my proposals?” General-purpose LLMs can draft text, but they lack the features that make AI proposal software effective for RFP responses:
| Capability | Dedicated AI Proposal Tool | General LLM (ChatGPT, etc.) |
|---|---|---|
| Learns from your past proposals | Yes | No (limited context window) |
| RFP compliance checking | Automatic | Manual |
| Knowledge base of certs, past performance | Built-in | Not available |
| Team collaboration | Multi-user with roles | Single user |
| Consistent brand voice across proposals | Trained on your style | Generic tone |
| Export to formatted Word/PDF | One click | Manual formatting |
For more detail, see our Bidara vs. ChatGPT comparison and Bidara vs. Microsoft Copilot comparison.
Choose by company size.
The right tool depends on your team size, RFP volume, and how quickly you need to see results. Here's our recommendation by segment:
Small Teams (1–50 Employees)
Priority: Time to value & affordability
You can't afford weeks of setup or $1,200+/month platforms. You need a tool that works with your existing documents from day one.
Recommended: Bidara ($299/month)
Also consider: Proposify ($49/mo) if you only need simple sales proposals, not RFP responses.
See our guide: Best RFP Software for Small Teams 2026
Mid-Market (50–500 Employees)
Priority: Team collaboration & scalability
You need tools that support multiple departments working on proposals simultaneously while maintaining brand consistency and institutional knowledge.
Recommended: Bidara Growth ($599/month) or Responsive (contact for pricing)
Enterprise (500+ Employees)
Priority: Integration, compliance & workflow
You need deep integrations with existing systems (Salesforce, SAP, etc.), enterprise-grade security, and complex approval workflows.
Recommended: Loopio or Responsive
Both require multi-week onboarding but offer the workflow complexity large teams need.
Government Contractors
Priority: Compliance & past performance tracking
Federal RFPs have unique requirements: past performance references, compliance matrices, and specific formatting. You need tools that handle these natively.
Recommended: Bidara (for speed across all RFP types), GovDash (for end-to-end federal GovCon), or RFP360 (for compliance depth)
See our guide: Best RFP Software for Government Contractors 2026

If you need a sales proposal, don't buy any of the above.
Everything on this page answers a solicitation: an RFP, RFQ, RFI, tender or security questionnaire that someone sent you. If instead you are writing an unsolicited pitch, quoting a price and chasing a signature, that is a different product and none of the 20 tools above is the right buy. Bidara included: our platform will not start a project without a solicitation document.
These four do that job. Prices are their own published rates as of July 2026.
GetAccept
Deal rooms, e-sign, contract management
Digital sales room covering opportunity through closed deal: proposal generation, e-signature, contract management and buyer engagement tracking. eSign tier at $25/user/mo, Professional at $49/user/mo with a five-seat minimum.
Qwilr
Interactive quotes with payment collection
Interactive web-page proposals with quotes, e-signature and payment collection. Starter $35/user/mo annually or $49 monthly, Growth $55, Scale $75.
Better Proposals
Lowest price in the category
Template-driven proposals and quotes with legally binding digital signatures. Starter $13/user/mo, Premium $21, Enterprise $42. Starter is capped at one user and ten sends a month.
Nusii
Flat monthly, not per seat
Proposal software for service businesses. Freelancer $29/mo, Agency $49/mo, Business $129/mo, priced flat rather than per seat. 60-day money-back guarantee.
We make no money telling you this. It is here because sending a rigour-first buyer down the wrong path costs more than the sale is worth, and because a comparison that never names its own limits is an advertisement.
Frequently asked.
Common questions from teams evaluating AI proposal software in 2026.
Do AI proposal tools train their AI on my proposals?
It varies, and certifications do not tell you. 7 of the 16 tools we checked state plainly that they do not train on customer content. Several others publish no position at all, and the most heavily certified platforms here are among them. See the full breakdown. Publishing no position is not evidence that a vendor trains on your data. It means you should ask, and get the answer in writing.
What does AI proposal software actually cost for a 5-person team?
Between $49 and $899 a month, and the headline price will mislead you, because this category bills 4 incompatible ways. A per-seat tool advertised at $89 costs more than a $299 flat plan once you pass three people. See the worked example.
Is there free AI proposal software?
There is no genuinely free RFP response platform. Conveyor offers a free tier, but it is focused on security questionnaires rather than full proposals. 6 tools let you evaluate without a sales call. A free tier and a free trial are different things: a tier is a product you keep, a trial is a window.
Can I use AI proposal software for sales proposals instead of RFPs?
Mostly no. Everything here responds to a solicitation someone sent you. Bidara will not start a project without a solicitation document. If you are writing an unsolicited pitch and chasing a signature, you want a sales-document tool instead: GetAccept, Qwilr, Better Proposals and Nusii.
What is the best AI proposal software in 2026?
For small and mid-market teams (1–500 employees), Bidara is the best overall choice thanks to its 60-second setup, AI that learns from your past proposals, and transparent pricing starting at $299/month. For large enterprises needing complex integrations, Loopio or Responsive are better fits despite requiring weeks of onboarding. See our comparison table for a full side-by-side view.
How much does AI proposal software cost?
Pricing ranges from $49/month for basic sales proposal tools (Proposify, PandaDoc) to $2,000+/month for enterprise platforms (Qvidian, Responsive). Mid-range tools like Bidara ($299-599/month) and AutoRFP.ai ($899/month) offer the best value for most companies. See our full pricing comparison for tier-by-tier details.
Can AI really write high-quality RFP responses?
Yes. Modern AI proposal tools generate original, on-brand content when trained on your company's past work. According to the APMP 2024 Benchmarking Survey, 68% of proposal teams now use AI in some capacity. AI-generated proposals typically need 20–30% editing time compared to writing from scratch, saving 15–20 hours per RFP response.
Which AI model or LLM is best for writing tenders and proposals?
General-purpose LLMs like GPT-4 or Claude can draft text, but dedicated AI proposal software outperforms them for RFP work. The difference: proposal tools train on your past proposals, enforce RFP compliance requirements automatically, and maintain a persistent knowledge base of your certifications, past performance, and case studies. See our comparison above and the Bidara vs. ChatGPT comparison.
What is the best AI tool for creating proposals?
The best AI tool for creating proposals depends on your team size and needs. For small and mid-market teams, Bidara offers the fastest time-to-value with same-day setup and AI that learns your writing style. For enterprise teams (500+ employees), Loopio provides robust workflow management. For government contractors, Bidara handles government and private-sector RFPs, while GovDash is purpose-built for federal GovCon workflows. See our small teams guide or government contractors guide.
Do I need a content library before using AI proposal software?
It depends on the tool. Traditional platforms like Loopio and Responsive require 4–8 weeks of content library building before generating your first proposal. Modern AI-first tools like Bidara work with your existing documents immediately: upload past proposals and company materials to start generating on the same day, with no setup period.
What's the ROI of AI proposal software?
Most companies see 150–300% ROI in year one from time savings alone. A team responding to 30 RFPs annually saves roughly 240 hours (8 hours saved per RFP, based on industry benchmarks). At a $75/hour blended rate, that's $18,000 in direct labor savings. The bigger ROI comes from bidding on 3–5x more opportunities, potentially adding $500K–$2M in new contract wins. Use our ROI calculator to estimate your savings.
Is AI proposal software suitable for government contracting?
Yes. Several AI proposal tools support government contracting workflows. GovDash is purpose-built for federal contractors with FedRAMP Moderate authorization and helped customers secure over $5B in contract awards in 2025. Bidara handles both government and private-sector RFPs across all industries. Key capabilities to look for: FAR/DFARS compliance, Section L & M parsing, compliance matrix generation, and past performance tracking. See our government contractor guide and federal contracting resources.
What is the fastest AI proposal software to set up?
The fastest AI proposal tools to set up are Bidara (60 seconds), Tribble (same day), and AutoRFP.ai (same day). These AI-first platforms work with your existing documents immediately, without requiring weeks of content library building. Traditional platforms like Loopio (4-6 weeks), Responsive (3-5 weeks), and Qvidian (4-8 weeks) require lengthy onboarding before generating usable output.
Can AI proposal software handle security questionnaires?
Yes. Several AI proposal tools now handle security questionnaires alongside RFPs. Conveyor specializes in security questionnaires with 95%+ accuracy and offers a free tier. Tribble processes DDQs and security questionnaires at 20-30 questions per minute. AutoRFP.ai and SteerLab also support security questionnaires as part of their RFP platforms. For dedicated security questionnaire automation, see also Vanta and Drata.
What is the difference between RFP software and proposal software?
RFP software is designed specifically for responding to formal Requests for Proposals with structured requirements, compliance matrices, and evaluation criteria. Tools like Bidara, Loopio, and Responsive are RFP-focused. Proposal software is broader and includes sales proposals, quotes, and pitches. Tools like Proposify, PandaDoc, and Better Proposals are sales proposal tools. Some tools like AutogenAI and Inventive AI bridge both categories with AI-powered content generation for both structured RFPs and free-form proposals.
About the Author
Founder & CEO, Bidara
Alexander Georges is the Founder & CEO of Bidara, an AI proposal platform that reduces RFP response time from 25 hours to under 30 minutes. A University of Michigan graduate (Magna Cum Laude, School of Information), he also serves as CTO at Craftle, a Techstars '23 company, and was featured in the Wall Street Journal for his work in AI-powered products.
He built Bidara after seeing firsthand how much time proposal teams waste on repetitive manual work, and how existing tools required weeks of setup before delivering any value. To build it, he researched and hands-on tested every major proposal platform on the market, evaluating their AI capabilities, pricing models, and real-world usability. He now works directly with proposal teams across government contracting, consulting, engineering, healthcare, and professional services.
This comparison is based on that hands-on evaluation, combined with publicly verified pricing from G2 and Capterra, vendor documentation, and feedback from Bidara users who previously used competing platforms.
