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
Theneo
Theneo is an AI-powered API documentation and developer-portal platform where engineers, writers, PMs and AI agents co-edit API references, guides and changelogs in real time, with generation from any spec, MCP and llms.txt for agents, and private per-customer portals.
- Generates a real docs draft from a spec
- Multi-role editing keeps docs from rotting
- Agent-consumable via MCP and llms.txt
- Private per-customer portals for B2B
- Overkill for a tiny, stable API
- Not a general internal wiki
- Customer and speed stats are vendor-stated
