A context-aware focus system
Pulse listens to your calendar, rhythm, and environment — then quietly reshapes what you see, hear, and notice. No blocklists. No timers. Just presence, when you need it.
The problem
Existing focus tools ask distracted people to predict their own attention.
We asked what a system would look like if it never interrupted to help.

Sensing layer · 01
Calendar density, typing cadence, ambient noise, heart variability, window focus, even the language you're writing in. Pulse fuses them into a single score — focus depth — and acts only when it's certain.
Recognizes open-plan noise, side conversations, and dropped-in messages — dampens what breaks flow.
Pulse learns the hours when your prose flows, when your code compiles cleanly, when your mind drifts. It stops scheduling deep work against biology.
Reads variability to catch stress spikes the moment they appear — before you notice the tightness in your shoulders.
Detects recovery windows after long calls. Delays Slack, mutes email, holds the door.
Faster fingers with fewer backspaces? You're in flow. Pulse protects it — silently.
