Writing on product specs, docs that live in the repo, and GitHub-native collaboration for product teams. specgit is a GitHub-native docs collaboration app: saves are commits, comments are pull request threads, publish is a merge — and your docs never leave your repo.
Spec drift isn't a discipline problem — it's a location problem. Decisions happen in the repo while the doc lives somewhere else. What changes when the spec sits next to the code, without asking PMs to learn Git.
A fair comparison of Notion and GitHub as the home for product specs — writing experience, review, history, permissions, AI agents, and tracking — and why the source of truth belongs in the repo.
AI PRD generators are genuinely good at drafting. But drafting was never the expensive part — the expensive part is where the spec lives afterward and how engineers review it. A fair comparison of the two, and why they solve different problems.
