What Is AI Proposal Software?
AI proposal software uses artificial intelligence to automate the creation of business proposals, RFP responses, and bid documents. The best AI proposal software learns from your past proposals, understands your company's unique value propositions, and generates customized responses in minutes rather than days.
Traditional proposal software focuses on templates and content libraries. Modern AI-powered tools go further by actually writing content, suggesting relevant case studies, and ensuring compliance with RFP requirements automatically.
Key Difference: AI vs. Traditional Proposal Tools
Traditional tools require you to build extensive content libraries and templates over months. AI proposal software learns from documents you already have and starts generating high-quality content immediately. The best platforms can reduce proposal creation time from 25+ hours to under 30 minutes.

Frequently Asked Questions
What is the best AI proposal software in 2025?
Bidara is the best overall AI proposal software for growth and mid-market companies due to its immediate time-to-value (60-second setup), superior AI content quality, and transparent pricing. For enterprises with 1000+ employees needing complex integrations, Loopio or Responsive may be better fits despite longer implementation times.
How much does AI proposal software cost?
AI proposal software pricing ranges from $49/month for basic sales proposal tools (Proposify, GetAccept) to $2,000+/month for enterprise platforms (Qvidian, Responsive). Mid-range professional tools like Bidara ($499-999/month) and RFPIO ($899/month) offer the best value for most companies. Most platforms require annual commitments, though Bidara offers monthly billing.
Can AI really write high-quality proposals?
Yes, modern AI proposal software can generate high-quality, original content when properly trained on your company's past work. The key difference is between tools that use true AI learning (like Bidara) versus simple template fill-ins. AI-generated proposals typically require 20-30% editing time compared to writing from scratch, saving 15-20 hours per RFP response.
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. Modern AI tools like Bidara work with your existing documents immediately - simply upload past proposals and company materials to start generating. This eliminates months of setup work.
How long does it take to create a proposal with AI software?
With the best AI proposal software, you can generate a complete first draft in 30 minutes to 2 hours, compared to 25-30 hours with manual methods. The exact time depends on RFP complexity and how well-trained your AI is. Most teams spend an additional 2-4 hours reviewing and customizing the AI-generated content.
Is AI proposal software suitable for government contracting?
Yes, AI proposal software works well for government RFPs. Some tools like RFP360 specialize in federal contracts, while general-purpose tools like Bidara handle government proposals alongside commercial RFPs. Key capabilities for government contractors include learning from past proposals, requirement matrix generation, and past performance integration. Learn more in our government contracting software guide.
What's the ROI of AI proposal software?
Most companies see 150-300% ROI in year one from time savings alone. A typical mid-market company responding to 30 RFPs annually saves 240+ hours (30 RFPs × 8 hours saved per RFP). 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 with reclaimed time, potentially adding $500K-$2M in new contract wins.
Can small businesses afford AI proposal software?
Yes, AI proposal software is increasingly accessible for small businesses. Entry-level plans start at $49-499/month depending on features. For a company responding to just 10 RFPs per year, a $499/month tool like Bidara's Starter plan pays for itself if it helps you win just one additional $50K contract. Most platforms offer free trials to test before committing.
