Session replay an AI agent can interrogate

Load a session, then ask what went wrong — at the exact millisecond it happened. When the agent cannot see, it asks you to look.

This Panel is DOM

Replaying a recording rebuilds the page as a live document. Every node is really there, and queryable, at whichever millisecond the playhead is on. That is why the tools register in this browser tab rather than behind an API: nothing on a server holds this DOM.

Load a recording

Three samples, one click each — or a recording of your own.

Getting WebMCP

WebMCP is how an agent finds the seventeen tools on this page. Turn it on in ChatGPT Desktop or Chrome, then the header pill should read live. Replay still works without it — only the agent needs the tools.

  • ChatGPT Desktop

    Open this page in the in-app browser, then turn site tools on:

    Settings → Browser → Permissions → Enable site tools

  • Chrome 149+

    Turn on , then reload.
