Deep work for developers
Built for the hours the standup never sees.
Team work is tracked, shared, kept in sync — the board, the tickets, the standup. Your own deep hours have no such room. Nothing in the stack records that the four real hours happened, or protects the next four. Particle is your desk, not the dashboard.

Where the deep hours go
Context is expensive
Loading a system into your head takes ten to fifteen minutes. One ping drops it. Research calls the leftover attention residue — you carry fragments of the interruption back into the code, and the rebuild starts over.
The day fragments around the calendar
Standup, review, one quick sync — and the morning is three slivers of forty minutes. Shallow hours and deep hours look identical in the calendar. Your compiler knows the difference.
The deep work is invisible
The ticket says done, the diff says +400. Nowhere does anything say: this took three hours of unbroken thought, and that is what made it good. Work that isn’t seen is work that doesn’t get protected.
What Particle gives you
Keyboard-first, all the way down
Command palette, single-key navigation, chord shortcuts. Every action is reachable from the keyboard — start a session, name the task, switch rhythms without touching the mouse.
A timer that counts up
No countdown pressure. The timer grows with the session, and overflow mode keeps holding the space when flow outlasts the plan. Stop at minute forty — those forty minutes still count.
Sound below the alarm range
Generative soundscapes engineered to disappear: nothing above 1,200 Hz on melodic content, no loops for your pattern-matching brain to latch onto. Or silence — if silence is working for you, use silence.
The deep hours, finally on record
Every session becomes a particle. Focus heatmaps and weekly reviews show where the real hours went — a quiet record of the work the tracker never sees.
Questions
Does Particle integrate with Linear, Jira, or GitHub?
No, deliberately. Your team tools track the work; Particle is where you do it. It sits beside the tracker, not inside it — no sync to configure, no second board to maintain.
Does it block Slack or other apps?
No. Particle never locks you out of anything. We think the discipline that lasts is the one you build, not the one software enforces.
Do I need an account?
No. Particle runs in your browser, free, without signup. An account only becomes useful when you want your focus history to follow you across devices.
