What Momentum OS actually does
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.
- Automatic session boundaries
- Topic-based tab clustering
- Zero setup required
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.
- Five semantic lanes
- Drag tabs between lanes
- Stale and duplicate tab detection
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.
- One-click session snapshots
- Full restore including lane state
- Automatic periodic checkpoints
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.
- Session summaries at a glance
- Unresolved-tab surfacing
- Calm, focused command center
No history permission, period
Momentum works from open tabs only — it never requests your browsing history. Everything it knows lives in chrome.storage.local.
- No history permission requested
- All data in chrome.storage.local
- No account, no cloud
The details that make Momentum OS feel like Momentum OS
Auto detection
Sessions form themselves from behavior.
Lanes
Researching → Comparing → Drafting → Done.
Checkpoints
Snapshot and restore entire sessions.
Resume briefs
Context back in one glance.
Tab hygiene
Duplicates and stale tabs, surfaced.
Momentum OS, up close
Not a policy summary. The actual behaviour.
No history permission — Momentum only sees open tabs.
Everything is stored in chrome.storage.local on your machine.
No account, no telemetry, no cloud sync.
Asked, answered
No — and it never asks for the permission. Sessions are built from your open tabs only.
