## What Chrobox is

Timeboxing is a time management technique where you assign every task a fixed slot in your calendar — a "time box" — and work on only that task until the box ends. Instead of an open-ended to-do list, your day becomes a sequence of concrete appointments with yourself: 9:00–9:45 write the report, 9:45–10:00 answer email. Because each box has a hard start and end, timeboxing forces you to prioritize what actually fits in a day, prevents single tasks from swallowing whole afternoons (Parkinson's law), and makes procrastination visible the moment a box slips. Research on implementation intentions shows that deciding when and where you will do something dramatically raises the odds you actually do it. Chrobox automates this loop: brainstorm tasks, pick priorities, drop them into hourly boxes, then review your day with an AI-assisted retrospective.
