IntentCheck
An AI documentation reviewer that compares your draft docs against recent merged PRs and architecture threads, flagging paragraphs that explain the 'what' but bury the 'why.'
developer advocates and technical writers maintaining SaaS and OSS documentation
- Side-by-side diff of each doc section against the merged PRs that touched that code path
- Intent-gap score per section showing missing trade-off, history, or constraint context
- Suggested questions to send back to the original engineer when intent cannot be inferred
- Enforced style and terminology guide so doc voice survives AI rewrites
AI-generated docs are getting fluent at describing code while erasing the rationale, and engineering teams have no tooling to catch intent loss before customers hit it
76% of docs teams use AI but only 44% have any review guidelines (State of Docs 2026 via Typescape); Mintlify at 8-figure ARR and 10,000+ companies confirms willingness to spend on doc tooling.Your AI docs passed the linter. Then a user filed a bug. ↗2025: A Year in Review - mintlify.com ↗
Mintlify ('self-updating docs'), Typescape (AI content review), Documentation.ai, and Vale/EkLine address adjacent failure modes (style, API staleness, content accuracy), but none specifically diff against merged PRs and arch threads for rationale loss; the 'why' check is an unfilled slice.Mintlify Pricing Explained: Plans, AI Credits & Real Costs (2026) ↗Your AI docs passed the linter.

Mintlify Pro at $450/mo and enterprise custom pricing proves B2B budget for doc tooling, but IntentCheck is a narrower review layer (likely plugin/audit SKU at lower price), so monetization is solid-but-not-exceptional.Mintlify Pricing Explained: Plans, AI Credits & Real Costs (2026) ↗Pricing - Mintlify ↗
AI doc debt compounds with generation speed; the Typescape piece explicitly argues governance gap is 'accelerating,' and 76% AI adoption is structurally rising — problem worsens as LLMs get more fluent.Your AI docs passed the linter. Then a user filed a bug. ↗
Buildable on GitHub PR API + an LLM diff/comparison pass (Mintlify and Typescape already ship similar infrastructure), but intent/rationale reasoning is harder than stale-API detection and requires arch thread ingestion.6 best AI writing tools for technical writers in 2026 - eesel.ai ↗6 Best AI Tools for Coding Documentation in 2026 - index.dev ↗
