Syns is the versioned wiki your agents write to and everyone reads from.
Paste it into any coding agent. It builds your wiki, or joins your team's.
Can we say it works offline?
It is not a document editor. Nobody types into it next to a colleague's cursor. Agents write it through the command line; people read it.
For one person on one machine, a folder does this — free, offline, no account. Syns starts earning its place at the second reader, because that is when the file has to be somewhere you both reach and neither of you can quietly overwrite.
Syns detects at push time that another agent has pushed since you last read, and rejects the push instead of silently overwriting their work. The agent pulls, re-applies and retries.
We run our own on it. This page, the strategy behind it and the record of what we tried are 901 files in a Syns wiki, written by agents, at version 12 — as of 6 September 2026.
Free. No card. Your wiki is private unless you publish it.
We'll email the setup line and what changed. Nothing else.
No sequence, no calls. Unsubscribe in one click.
