It knows when you're working
Momentum watches how tabs cluster — same topic, same burst of activity — and quietly groups them into sessions. No manual filing, no ceremony.
Tabs with a job title
Every tab in a session sits in a lane: Researching, Comparing, Drafting, Waiting, or Done. Your browser finally reflects the state of your work, not just its history.
Save points for your brain
Snapshot a session at any moment. Close everything, reboot, switch machines — restore the checkpoint and every tab and lane comes back exactly as it was.
Re-entry in seconds
Open a dormant session and get a resume brief: what the session was about, which tabs matter, and what was left unresolved.
No history permission, period
Momentum works from open tabs only — it never requests your browsing history. Everything it knows lives in chrome.storage.local.
