Is ReWrite safe?

Clean risk

ReWrite sends Gmail subjects and popup writing prompts to Cohere's generation API when the user clicks Generate.

In Gmail, ReWrite adds a Generate button beside subject fields and uses the subject text to build an email-writing prompt for Cohere. The popup also combines user-entered context and instructions into a prompt sent to Cohere, then displays the generated response.

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.

Where it sends data

Destinations our analysis observed ReWrite 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.

  • api.cohere.ai

    ReWrite sends data to api.cohere.ai. One other extension we have analysed sends data here.
