What syncs across computers?
The data Kortex uses to organize your work syncs to your Kortex account. It appears on your other computers. The extension’s own docs list it as prompts, tags, notes, templates and similar organizing data. Workflow definitions and source tags sync as well.
What does not sync
Some things stay on one computer on purpose:
- prompt versions and Recently deleted
- your prompt use history
- automation run history
- whether an automation is switched on or off
If you turn a rule off on your laptop, it still runs on your desktop.
Not a backup of your notebooks
Your notebooks, sources and Studio outputs live in Gemini Notebook, in your Google account. Kortex syncs the organizing layer on top: the tags, prompts, notes and templates. It is not a copy of your sources, and it does not restore a deleted notebook.
Signing in
Kortex needs you signed in to sync prompts and views across devices. Kortex talks to Gemini Notebook with your own Google session, from your browser. Its servers never see your Google sign-in.
