Your docs are lying to you, and git is the only honest one in the room

You know the moment. You open a doc, you trust it, you build on it — and it turns
out that doc has been lying to your face since a refactor three sprints ago.
Nobody updated it. Nobody even knew it went bad. It just sat there, smiling,
being wrong.

Now hand that same doc to an AI agent. It reads the lie, believes it harder than
you did, and cheerfully re-implements the exact decision you spent a week killing
last quarter. Cool. Love that for us.

So we built Sync, around one stubborn idea: docs that can't quietly rot.

The fun part

You don't write the docs. Your agent does — while it's actually working, not at
2am the night before a review.

And git? Git becomes the snitch. The second a commit moves past a doc, Sync slaps
a big STALE sticker on it and points at the exact commit and files that did
the crime. No audits, no "uhh is this still true," no archaeology. Staleness turns
into a to-do list instead of a jump-scare.

Your job shrinks to the part that needs a human with taste: you skim, you nod, you
go "no, that's wrong" — inline, like leaving comments on a PR. The agent always
starts from stuff it knows is actually fresh.

Three ways in, one source of truth: a desktop app, a git sync CLI, and an MCP
server for Claude Code, Cursor, Zed, OpenCode, Codex — and now Antigravity.
It's all just plain files in your repo. No SaaS, no login, nothing phones home.
Your secrets stay your secrets.

What's new

This update is quietly turning Sync into a mission control for your agents:

Flip between projects in one window (RIP, 14 floating windows)
Run a few agent chats side by side in the same project
Little live badges when an agent is grinding away in another project
The Roadmap now groups your specs by section, like a grown-up
New friend: Antigravity
Fresh onboarding + a small mountain of bug fixes

Go break it

Sync is 100% free, fully private, open source, and gloriously alpha. We're
building the whole thing out in the open:

Clone it, sic your agent on it, watch the docs and roadmap fill themselves in.
Then hit the comments: what's the dumbest thing a lying doc (or an agent that
believed one) ever cost you? Tell us — that's literally how we decide what to
build next. 🫡
