Both vendors now ship first-party schedulers, so the 2025 advice to reach straight for cron is out of date. ChatGPT has scheduled tasks on Plus, Pro, Business and Enterprise, including monitoring tasks that only notify you when something has actually changed. Anthropic has no scheduler in plain Claude chat, but it has four elsewhere: recurring tasks in Claude Cowork on any paid plan, routines in Claude Code that run on Anthropic's infrastructure, local scheduled tasks in Claude Code Desktop, and scheduled posts in Claude Tag for Slack. Almost all of them share an hourly floor, so anything more frequent means an automation platform or your own cron. None of that is the difficult part. Setting up a schedule takes ten minutes; the project is getting the AI to the data the report needs, keeping it from doing arithmetic in its head, putting the output where the team already reads, and noticing when a run quietly stops working. Anthropic documents that last one with unusual candour: for routines, a green status means the session started and exited without an infrastructure error, not that the task in your prompt succeeded.
