Drift Catcher
Gently catch your focus drift.
A quiet macOS menu-bar companion for deep work. Start a focus session, say what you're working on, and an on-device AI quietly notices the moment your attention slips — then tells you why, in your own words.
The two magic moments
A soft nudge mid-session
When you slip onto X, YouTube, or another distracting app for a couple of minutes, the screen edges quietly darken — a gentle reminder, never a nag.
A reflection at the end
"You drifted right after switching from Slack" — a short, on-device reflection with a gentle suggestion for next time.
100% on-device, 100% private
- • All AI runs on your Mac. When Apple Intelligence is available and turned on, Drift Catcher uses it — nothing to download. Otherwise you can choose to download Gemma 3, an open model from Google (about 3 GB, one time); it downloads only when you click Download. Without a model, you still get a simple on-device recap after each session.
- • Screen content never leaves your Mac. Only the name of the app you're using and its window title are read to tell whether you're on task — never message or document contents, and never your keystrokes.
- • No accounts, no tracking, no analytics sent to anyone — ever.

Gentle by design
- • A calm amber dot in the bottom-left corner. Hover and it asks "Still focusing?" — answer Yes (or press ⌃⌥⌘D from any app), or take a short break.
- • Pick 25, 45, or 90-minute sessions.
- • An optional "Session complete" notification when your timer runs out.
- • A tip to switch on a Focus so notifications stay quiet.
- • Reflections in English, 한국어, 日本語, or Español.
Drift Catcher doesn't block apps or shame you with streaks. It just helps you notice — and understand — your own drift, privately.
Insights, for your eyes only
A built-in Insights view shows your focus patterns — sessions, total focus time, what tends to pull you away, your best hours — all computed and stored locally. Export a snapshot as JSON or Markdown whenever you like. It's your data; it stays yours.
Requires a Mac with Apple silicon and macOS 14 or later.
