Message navigation

Use AI-MarkDone to move through long ChatGPT threads and return to your reading position after sending a new prompt.

Use this when

You often read older answers inside a long ChatGPT thread. Once the thread gets long, scrolling becomes expensive. If you send a new prompt while reading, it is also easy to lose the exact spot you were using.

Where to open it

These features work directly on the ChatGPT page. To adjust them, open the AI-MarkDone extension panel, go to Settings, then find ChatGPT page behavior.

How to use it

  1. Open a long ChatGPT conversation.
  2. Use the lower-right Previous / Next buttons to move between nearby messages.
  3. If you prefer the keyboard, keep Use arrow keys to move between messages enabled in Settings.
  4. When reading an older message, send a new prompt when needed.
  5. With Restore position after sending enabled, AI-MarkDone tries to bring you back to the spot you were reading.

Worth knowing

  • Restore position after sending tries to return quickly, but the page may briefly move while ChatGPT is rendering.
  • If you want the quietest page possible, you can hide the lower-right buttons and keep keyboard navigation.
