Docs go stale when they live away from the code. Today the spec lives in a doc app, the code in GitHub; engineers get a Slack link, read it once, and build from the ticket โ then the doc no longer matches reality.
specgit is the PM-friendly layer on top of GitHub. You write the spec like a regular doc. Engineers review it as a pull request โ same flow, same tools, same habits. Every update is a commit. Every discussion is on the record. The doc sits where engineers and AI coding agents already look.
How it works - Saves are commits - Comments are PR review threads - Publish is a merge
Docs never leave your GitHub.
Write without Git or Markdown - Visual editor โ no Markdown or Git required - Inline comments and live collaboration - Full history โ every change is a commit - Starter templates (product spec, decision record, meeting notes) - Import Word, PowerPoint, Excel, and PDF (via Microsoftโs MarkItDown) - Obsidian Markdown (wiki links, callouts, Mermaid; unknown syntax preserved) - View changes โ Word-style redlines against main
GitHub-native review When a repo requires approving reviews, specgit shows whatโs needed, authors can request review; reviewers approve or request changes in-app. โPublish when approvedโ goes live on approval. Works with branch protection and rulesets.
specgit AI (optional) Agent chat, Review, and Triage โ text or voice. Only when invoked; every change needs your approval. Never trains models. FreshSpec โ early access on request.

GitBookNo features have been listed yet.
Based on our record, GitBook seems to be more popular. It has been mentiond 6 times since March 2021. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
GitBook is simple and clean, and sometimes thatโs exactly what you need. I like it for early-stage products or teams with lighter documentation. Youโll eventually hit limits if your structure gets more complex, but if simplicity is your priority, itโs a solid choice. - Source: dev.to / 8 months ago
TL,DR: LaunchDarkly is great for B2C companies. Bucket is for B2B SaaS products, like GitBook โ a modern, AI-integrated documentation platform. - Source: dev.to / over 1 year ago

Good question that led to insightful responses. I would like to bring GitBook (https://gitbook.com) too to the comparison notes (no affiliation). They, too, focus on the collaborative, 'similar-to-git-workflow', and versioned approach towards documentation. Happy to see variety in the 'docs' tools area, and really appreciate it being FOSS. Looking forward to trying out Kalmia on some project soon. - Source: Hacker News / almost 2 years ago
You can have both a landing page (e.g.: www.your-project.dev) and a documentation website (e.g.: docs.your-project.dev). For creating documentation website GitBook is better fit than Gitlanding. GitBook is free for open source Projects (you just need to issue a request). - Source: dev.to / over 4 years ago
