How TimeUno works

Two timelines

TimeUno records two things side by side:

• Your attention. The app or website in front of you, its window title, and when you were idle. The desktop app records this, and the browser extension adds the site you’re on.
• Your AI tools. When Claude Code, Cursor or another AI tool is working, waiting for you, or done, even in a background terminal or tab.

Joining the two shows time no ordinary tracker can see: work your AI did while you were in a meeting, and time you spent waiting on an agent.

How time is classified

Every stretch of time gets:

• a category: coding, design, writing, email, communication, meetings, research, learning, marketing, sales, admin, browsing, social, entertainment or other;
• a verdict: productive or unproductive. There is no third option.

Most time is placed by built-in rules (an editor is coding, a calendar is admin). Apps that can go either way, such as Slack, YouTube or X, are judged from the window title, the site and what you were doing. Time that rules can’t place is sent to an AI classifier that receives only the details listed on the privacy page.

You have the last word

If TimeUno gets something wrong, change it once. It remembers the correction for the next time, and repeated corrections become rules. See Corrections and rules.

Idle time

Time with no keyboard or mouse input is marked idle and kept apart from the time you were working. TimeUno counts how many seconds had any input, never what you typed or where you clicked.
