Is Coursera Summary with ChatGPT and Take Notes safe?

Low risk

Coursera Summary with ChatGPT and Take Notes signs NoteGPT API requests from bundled extension credentials.

The extension includes NoteGPT/ExtensionDock signing material in its content script and uses it to request model configuration from notegpt.io. The same flow can send page transcript text to ExtensionDock summary services for AI-generated summaries.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.

Shared hosts - 1 hostname

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
