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.

We have 100s of different screens to migrate as well as a really large design system, and to date we've been successfully using the invisionapp.com website to keep things really well organized and easy to navigate with tags, pages, etc. We've enjoyed this system so far because it's easy for PMs and Devs to navigate in a website format, without having to learn the design software or get bogged down in artboards.
