Status
Perplexity Comet is Beta.
The integration path is built and tested. Customers can attach now; expect minor breaking changes until the 1.0 contract freeze.
How to attach
Browser instrumentation.
Issue a workspace API key
Generate a key in the dashboard under Settings → API Keys, scoped to the workspace and environment this agent's data should land in.
Install the instrumentation
Load the Intramedial browser extension unpacked from the repo (`chrome://extensions` → Developer mode → Load unpacked) — the Web Store listing is not up yet for desktop use, or build the Intramedial-instrumented Chromium image from `browser-extension/chromium/Dockerfile` (it is not on a public registry yet) for headless runs. Perplexity Comet's activity is observed at the click and DOM-event layer.
Verify
Trigger one agent run. The Witness page shows the record once the agent has emitted it.
