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.
