The accuracy question
AutoRFP uses GPT to generate answers from a combination of your documents and general knowledge. This is fast and covers more questions — but it also means the AI may produce plausible-sounding answers not backed by your actual policies. In security DDQs, a wrong answer isn't just unhelpful — it creates legal liability and can lose deals.
Source citations change the game
When a buyer's security team asks "where did this answer come from?", FillBase points to the exact document and section. AutoRFP's partial citations mean some answers lack traceable evidence. For enterprise buyers who audit responses, this is the difference between a smooth close and a follow-up round.
Frequently asked questions
Is AutoRFP cheaper than FillBase?
AutoRFP starts at $69/month vs. FillBase's free tier. For paid plans, AutoRFP's mid-tier and FillBase's Starter ($149/mo) are comparable. At the high end, both reach ~$599–$899/month.
Can I switch from AutoRFP to FillBase?
Yes. Upload your existing knowledge base documents and past responses. Your investment in content transfers — FillBase builds its knowledge from the same source documents.
Does AutoRFP hallucinate answers?
GPT-based systems can generate plausible answers from general knowledge when your documents don't have the answer. AutoRFP mitigates this, but the risk is inherent in the approach. FillBase flags unknown questions instead of guessing.
