Dosu
Dosu captures knowledge automatically from coding agent sessions, keeps documentation updated when source code changes, and connects GitHub, Confluence, Notion and Slack into one source of context. It states 50% fewer tokens burned, 2x faster agent performance and 200k+ engineers using it.
- Inverts documentation economics by capturing rather than requiring writing
- Ties doc updates to the change that caused them, which removes drift structurally
- Consolidating context sources resolves duplication and contradiction between systems
- The built-in library index addresses agents getting third-party APIs wrong
- Captured wrongness is worse than no documentation, since it will be trusted
- Whether captured knowledge is reviewable before becoming authoritative is unstated
- The 50% and 2x figures carry no published methodology
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
