Is Writeseed - Smart AI Assistant safe?

Low risk

Writeseed - Smart AI Assistant writes the same extension user ID into page storage on every HTTP(S) site.

The content script runs on all HTTP and HTTPS pages, gets or creates a stable user ID, and saves it as joviuuid in the page's localStorage. Because this is page storage rather than extension-only storage, scripts running on each visited site can read the same identifier.

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