Yotai gives your Cowork skill files a save history. See exactly what changed, who changed it, and when — roll back to any version, and branch off to experiment — whether you're working solo or with a team.
You are a research assistant helping the user find relevant information.
Be concise. Answer in 2–3 sentences max.
Be thorough. Provide context, nuance, and follow-up questions to deepen understanding.
Always cite your sources and explain your reasoning.
Sub-agents are the same. You edit the prompt, it starts behaving differently, and you can't remember what it said before. Or you try a new version and it's worse — but you already overwrote the old one. Or you have two ideas and no good way to try both.
01
Every save is kept. Browse the complete timeline and see exactly who changed what, and when.
02
Try a different approach on a branch without touching the working version. Merge it when it works. Delete it if it doesn't.
03
One click restores any previous version to disk. No manual copy-pasting. No lost work.
The mental model
Without Yotai, editing a skill file is like editing a document with no undo history beyond the current session. You can see where you are, but not where you've been — or why the old version worked better.
With Yotai, every change is tracked. You can see the exact lines that changed between any two versions, who changed them, and why. Two ideas for the same agent? Branch off and try both.
