Give your tabs some room 
01 / The idea
Tabs that float.
Memory with a source.
Your work doesn’t move in straight lines. Give each train of thought its own group. Keep a quotation with the page it came from. Return to a workspace without starting over.
02 / Room to move
A little less bar.
A little more sky.
Pull a group away from the top edge. Let it float. Bring it back when you want it docked. The connection follows your movement.

03 / In the browser today
A place for the things you return to.
Browsing, saved knowledge and recorded viewing, in one native Mac application.
Groups with freedom.
Float tab groups, dock them along the window edges and rearrange your tabs.
Pick up the thread.
Persistent sessions and explicit workspace checkpoints keep your tabs and arrangement available.
Keep the source.
Browser Brain saves selected quotations with sources. Retrieve by keyword or optional local semantic search. Export as JSON or Markdown.
Links, in order.
Search and edit bookmarks. Give them categories and an order that fits your work.
Watch for a change.
Public-page watchers record observations from supported public sources while the app is active.
04 / Privacy & permission
On your Mac.
On your terms.
Browser data stays local. The controls make the boundaries explicit.
A separate private session
Private browsing uses a nonpersistent web session and excludes normal persistent history, Brain, media and learning records.
Optional models, explicit consent
Model downloads require your permission. Files must pass integrity verification before they are used.
Cloud research has its own permission
Provider-backed research needs separate configuration and cloud permission. Ordinary browsing does not require an AI model.
05 / In motion
Still finding its shape.
Next: broader compatibility and acceptance work.
Next: Developer ID signing and notarized distribution.
