Every AI product now runs work on a timer: a brief built before you sit down, a check-in drafted an hour before the meeting. The vendors' pages differ on what a run can reach, how often it runs, and what happens when a run needs a yes and nobody is there. Spec Sheet 04 puts the five pages side by side, in plain words traced to each vendor's own page. The descriptions are ours; the two short quotes are the vendors'. The desk jobs and the human lock are ours, and the header on each page says which voice you're reading.
The rule to keep is on page 3. ChatGPT's page says a task that needs approval pauses until you review it. Google's says Gemini is designed to ask before it sends, changes your data, purchases, submits a form, or signs in with Google, and that a schedule running while you're offline may complete an action you can't stop. Claude's Cowork pages describe three modes and an approval mode field on the scheduled task, and say nothing about a run that pauses with nobody there; the Claude Code Desktop page says a local task in Manual mode "stalls until you approve it." Grok's and Copilot's pages say nothing about approvals. Under the table sits the human lock: a scheduled run reads and drafts, and nothing it makes leaves your desk until you've read it.
Page 4 is the routing. The morning brief and the Thursday check-in draft run without you, from a calendar and inbox the run can only read. A Friday run that lists the week's open questions with their dates thinks with you. A monthly board update drafted from the program tracker is built from what you describe. Every run reads, then saves a draft; before the first run, allow its reads and set anything that writes to ask first.

Checked against the sources Oct 21, 2026. Two Google pages disagree on whether a task schedule runs with the device off; both are cited. Caps and plan names are as printed on the day. If a row on this sheet stops matching its source, this post gets a RETIRED line at the top.
