Done Ping

Reasoning models and deep research can take minutes. Done Ping tells you the moment ChatGPT, Claude, Gemini or Perplexity finishes, so you can work somewhere else instead of watching the dots.

Free for one site. Pro is $4.99, paid once.

Questions

Is this made by OpenAI, Anthropic, Google or Perplexity?
No. Done Ping is an independent extension by Otter Potter and is not affiliated with any of them.
What does it read?
Only whether each site is still writing (its Stop button), plus the tab’s title and address for the notification. It doesn’t read your conversations.
What leaves my computer?
Nothing, unless you turn on phone alerts. Then the site name and how long it took go to your own private ntfy topic; the chat’s title never leaves your computer. See the privacy policy.
