GitBook
GitBook is a documentation platform that syncs with your repository for docs-as-code workflows, proactively flags content that no longer matches your product, answers user questions through an AI assistant, and connects to Claude, ChatGPT and Cursor through MCP so agents can read your docs directly.
- Treats AI agents as a real documentation audience rather than an afterthought
- MCP means assistants read your current docs rather than a stale crawl, so corrections propagate
- Stale-content detection addresses documentation's actual failure mode rather than its authoring
- AI Insights turns docs into something measurable — which page failed, not which page was viewed
- No pricing or seat structure published, and seat cost determines who can actually contribute
- No accuracy data for stale detection or the AI Assistant
- Stale detection realistically catches clear divergence rather than subtle drift
Swimm
AI code documentation that stays in sync with your codebase Category: Coding & Development.
- Keeps documentation synced with the actual codebase
- Strong IDE integration and in-editor answers
- Privacy-friendly: code stays in your repos and is not used to train models
- Documentation coupled to code that auto-flags when code changes
- Requires adopting a docs-as-code discipline to get full value
- Learning curve for teams unfamiliar with coupled documentation
- Swimm is strongest in its core use case, not every niche
