Desktop app · early access
Momentum, running quietly on your machine.
The desktop app is what turns Momentum from a browser demo into a real agent — it sees the window you're actually working in and feeds that straight into the same focus sessions you tried on the homepage.

Active window detection
Knows whether you're in your editor, docs, or somewhere else — no browser tab required.
Idle detection
Notices real inactivity, not just tab switches, and folds it into your session analytics.
Local-first
Raw activity stays on your machine — only the summarized context is sent to the agent.
