Momentum quietly captures what you do — screen, voice, app activity, calendar — and at the end of every day writes you a paragraph about what actually happened. No filling forms. No journals. A journal that writes itself.

You type the goals. You log the work. You write the reflection. The cognitive overhead of using the tool eventually exceeds the productivity it gives back. Momentum flips that — it sees what you actually do, then writes the paragraph.
Three movements running quietly behind your real work.
ScreenCaptureKit grabs a frame every 60s. AVFoundation records voice on a global hotkey. NSWorkspace knows the active app. EventKit reads your calendar. Four signals into one Event log.
Gemini turns screenshots and audio into structured events — app, project, urgency, intent. Text-only prompts route through a small backend proxy for caching and cost tracking; binary stays direct.

Capture, write, focus, look back. Built around how you actually work.
An editorial paragraph for your day. Hourly digests for the right rail. Written in your name, not at you.
