How to know when ChatGPT has finished a long answer without watching it
Updated October 10, 2026 · By Otter Potter, the maker of Done Ping (not neutral; we say where it matters).
The better the model, the longer the wait. A hard question or a research task can run for minutes, and some users have timed single answers at well over an hour. So you switch to another tab, and twenty minutes later remember to check. People have been asking for a notification when the response is complete and for a sound when a reasoning task ends for a long time. Until that exists everywhere, here are the options.
1. Keep it in view (free)
Put the chat in its own narrow window beside your work, so you can see the answer arrive from the corner of your eye. On Windows, drag the window to the screen edge to snap it; on a Mac, hover the green button and choose a side. Simple, and it costs you screen space.
2. Use the phone app for long jobs (free)
The phone apps can send a notification when some long jobs finish, such as a research report. Start the job on your phone, or check whether the one you started on the computer shows up there. Which jobs notify, and when, varies by app and changes with updates, so try it once before relying on it.
3. Ask for the work in stages (free)
A long silent wait is sometimes avoidable. Ask: “Give me the outline first, then wait for me.” You get something to react to in seconds, and you only wait for the long part once you know it’s heading the right way.
4. A notification on your computer
Done Ping (we make this) shows a desktop notification the moment ChatGPT, Claude, Gemini or Perplexity finishes, with a short chime and a check mark in the tab title until you look. Click the notification to jump back to that chat. You choose how long an answer must take before it pings, so quick replies stay quiet. It only checks whether the site is still writing; it doesn’t read your conversations.
What it can’t do: it works in a desktop browser, not the phone apps, and the tab has to stay open. The free plan watches one of the four sites.
Questions
- Will the answer keep going if I switch tabs?
- Yes. The work happens on the AI company’s computers, not in your tab. Closing the tab is different: some jobs carry on and some stop.
- Why not just listen for a sound from the site?
- We haven’t found a setting on any of the four that plays one for an ordinary answer.
- Is Done Ping made by OpenAI, Anthropic, Google or Perplexity?
- No. It’s made by Otter Potter and is not affiliated with any of them.
