Automatic time tracking
for Codex.
OpenAI’s coding agent for the terminal and IDE. Connect it to Temporal.ist over MCP and Codex becomes your time tracker: start timers, log hours, fix entries, pull reports and send invoices — by saying so. Underneath, automatic time tracking keeps capturing your work from file changes and URLs. No screenshots, ever.

Codex time tracking, in plain language
- “Create a project called Dunder Mifflin and start a timer.”
- “Add 3 hours to Dunder Mifflin yesterday — researching deployment.”
- “How much time did I spend on client work this week?”
- “Move this morning's entry to the right project.”
- “Stop the timer — actually, I stopped at 17:00.”
Nineteen tools cover the whole workflow — timers, backdated time logging, corrections, typo-tolerant project lookup, pause-aware reports in your timezone. Every session Codex creates is labeled in your dashboard, so you always see which hours came from AI time logging and which from automatic tracking.

Codex invoicing: from tracked hours to a sent invoice
“Invoice Dunder Mifflin for July.” Temporalist gathers the unbilled sessions, builds a draft with line items per project — pause-aware hours times your rates, rounded up per your billing defaults — and hands Codex a link for you to review. Only after you explicitly confirm does the invoice get emailed to your client. Billing and customer data are extra secured behind their own off-by-default setting, so nothing sensitive moves until you allow it.

FAQ
How does time tracking using Codex work?
Temporal.ist runs a remote MCP server at https://temporal.ist/mcp. You connect OpenAI Codex once, sign in, and from then on you talk: “start a timer for Dunder Mifflin”, “add 3 hours yesterday”, “how much time did I spend this week?”. Codex calls the right tool and the result lands in your Temporalist ledger — the same one the automatic tracker fills from file changes and URLs.
Is this automatic time tracking for Codex, or manual?
Both halves are covered. The Temporalist desktop app and browser extension track automatically — file saves and URLs become sessions without timers or screenshots. Codex adds the conversational half: backdated time logging, corrections, questions and invoicing for everything automation can't see.
Can I do Codex invoicing — turn tracked hours into an invoice?
Yes. Ask Codex to invoice a client and Temporalist builds a draft from your unbilled sessions — line items per project, pause-aware hours times your rates, with your round-up rules applied. Nothing is emailed until you explicitly confirm, and invoicing requires the sensitive-data opt-in in your settings.
Can Codex log the time I spend coding automatically?
Two layers work together: the Temporalist desktop app tracks file changes automatically while you code, and Codex — connected over MCP — handles everything else in plain language: backdated entries, corrections, reports, and invoicing, without leaving the terminal.
What does Codex time tracking cost?
Temporal.ist is free to start — automatic tracking included. The MCP connection for Codex (and every other assistant) is part of Temporalist Pro; one subscription covers all your connected clients.
