who uses it, and why
Who lets the AI drive Chrome.
People with many profiles, and more bookmarks than order.
a team lead
A bookmarks bar sorted, sync intact.
whyHand edits come back after the next sync.

a new hire
The team's links, on day one.

what you can ask
Your AI opens the right profile and edits bookmarks so sync keeps them.
Each profile maps to its account in Chrome's Local State. The AI works from that map.
Open a window in a profile
On a Mac, Windows or Linux.
Read a profile's bookmarks
From its Bookmarks file. Its ids are the API's ids.
Change bookmarks, in sync
Through the bookmarks API, so sync records each change.
A copy before a bulk change
The Bookmarks file is saved beside itself first.
Read pages and fill forms
That is Claude in Chrome, the extension paired with Claude Code.
where the credential stays
Your AI drives Chrome with one setting of yours, and no extension of ours.
No account or token involved. Chrome is already signed in as you.
in Chrome
On a Mac, turn on Allow JavaScript from Apple Events, once. Other paths crash Chrome or fight sync. The bookmark manager page does neither.
in your brain
A page names your profiles by account, and your bookmark folders.
what instibrain never touches
Nothing edited by hand or guess.
Chrome stays signed in as you. Our server holds the profiles page.
- A bookmarks file edited by hand.
Sync would restore the old version or duplicate bookmarks.
- A change to an unchecked id.
Each id is checked against its URL first.
- A window you opened.
The AI opens and closes its own helper window.
the limits
Your AI changes bookmarks only on a Mac, and opens profiles everywhere.
One platform boundary, and one setting of yours.
| Limit | What it means |
|---|---|
| The bookmark steps need a Mac | Profiles and windows work everywhere. |
| A setting is yours to turn on | Apple Events JavaScript stays off until you enable it. |
before you connect it
Your AI changes bookmarks, and Chrome sync carries them to your other devices.
Does instibrain install anything in Chrome?
No. The AI drives your own Chrome. Claude in Chrome is yours to install.
Will my other devices see the change?
Yes. Changes go through Chrome's own API, so sync records them.
What if a bulk change goes wrong?
The saved copy of the Bookmarks file restores it.
Your browser, driven its own way.
Name your profiles and folders once. Claude Code and Codex then open the right window as you.
