Timers
Start, pause, resume and stop the live timer, and name the task you are on.

Off until you allow it. Manage clients, draft invoices, and send one after you confirm.

Careful by default
Confirm before it counts
Deleting an entry and sending an invoice always show a preview first, and need your yes.
Client data stays off
Client and invoice tools only work after you allow assistants to handle that data, in Settings.
Your sign-in, your scope
Assistants sign in through Temporal.ist like any app. API keys can be limited to reading.
Revoke at any time
Each connected assistant is listed under Devices and connections. Revoking signs it out at once.
Using another assistant? Claude, Codex, Gemini, Copilot, Kimi and OpenCode.
