Is OptiSearch safe?

Clean risk

OptiSearch sends search queries to ChatGPT when its assistant is invoked on search results pages.

When you use the OptiSearch assistant, the extension reads the current search term from the results page and uses it as the prompt. It obtains your ChatGPT session and sends that prompt to chatgpt.com/backend-api/conversation with ChatGPT credentials.

Shared hosts - 4 hostnames

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.

What it can do

Permissions this extension asks for, as declared in version 4.2. Asking for a permission is not a finding on its own - it is what the extension can do if it chooses to.

Where it sends data

Destinations our analysis observed OptiSearch contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
