Comparison
Untimely vs ChatGPT Scheduled Tasks
ChatGPT scheduled tasks run a prompt on a schedule and notify you by push or email inside ChatGPT. Untimely schedules events that can email you or call any HTTPS endpoint — including your own agent endpoints — with API keys, run history, flexible random windows, and no cap on events for Pro accounts.
Answer first
Choose by the work you are scheduling.
Best when
- The scheduled output must reach a system, not just a chat: Untimely webhook actions call any public HTTPS endpoint, which ChatGPT tasks cannot do.
- You need more concurrent schedules than ChatGPT allows — its active-task caps range from 3 to 15 depending on plan.
- Trigger times should vary inside a window so a recurring prompt does not become ignorable clockwork.
Tradeoff
- ChatGPT tasks are the better pick when the job is having the model research, reason, and summarize for you on a schedule, inside the chat product you already use.
- Untimely is the better pick when the schedule must trigger software — webhooks, agent endpoints, Slack incoming webhooks — or when you need event history and API-driven management.

FAQ
Questions about ChatGPT Scheduled Tasks
Can ChatGPT scheduled tasks call a webhook?
No. OpenAI documents notifications by push and email only. Untimely webhook actions call any public HTTPS endpoint with your chosen method, headers, and body.
How many scheduled tasks can each product run?
As of July 2026, ChatGPT caps active tasks by plan — roughly 3 to 15 depending on tier. Untimely's free tier is limited to 3 events, and the Pro plan removes the event cap.
Can Untimely still use GPT to write the message?
Yes. Email actions support GPT-generated content, so a recurring prompt can vary its wording on every run instead of repeating a static reminder.
