AI drafting and accuracy
Can AI replace manual RFP writing?
Short answer
Not fully. AI now drafts a large share of a typical response, and 10 tools publish their own figure for it: Tribble, Realm, SiftHub, TrustCloud, Vanta, Anchor and 4 more. Use AI for the first pass on repeatable questions and keep people on pricing, legal commitments, win themes and anything the sources do not support.

Why this question matters
The percentages below are vendor-reported and measured on their own customers, so they are not comparable with each other. They still show the shape of the job: most of the repetitive answering can be drafted, and the human work shifts to checking, tailoring and deciding what to commit to.
Which one fits your situation
- If you want to check each AI draft against its source, start with Tribble, Realm and SiftHub.
- If you are a small team buying without a sales cycle, start with DeepRFP.
What to test in a trial
- Run a finished RFP through each tool and count drafts your reviewers accept unchanged.
- Time the review, not the draft: that is where the hours go.
- Check which questions the tool leaves blank or flags, and whether that list makes sense.
Caveats
- Every percentage here comes from the vendor. None is an independent benchmark.
- Draft rates depend heavily on how much approved content you load first.
How we decided who qualifies
Only RFP, DDQ and questionnaire response tools with a published profile are checked. A tool is named here only when its record shows the rule above, either in a sourced research fact or in the reviewed profile, and we publish an answer only when at least three tools qualify. A tool missing from the table may still do this; it has not been documented in a way we could source. Read the research methodology for how facts are dated and corrected.
More questions on this topic
Will AI replace proposal managers?
It removes much of the copying and first drafting. Strategy, pricing, review and buyer-specific tailoring still need people who know the deal.
Which RFP questions should never be AI-drafted without review?
Pricing, contractual commitments, SLAs, security claims and anything quoting a customer or a number.
How do I measure AI drafting quality?
Measure accepted-without-edit rate and reviewer minutes per question on a response you already submitted.
