Assessment

Browser assistant: low

Reasoning: The Brave browser's built-in assistant. No storage, no training and local history are stated plainly, and the page-summary mode is explicit that page content is sent. Region is not named, and page content still leaves the browser for whichever model is selected.

Flags: Page content and tab titles sent to the backend on request · Region not stated · Assessed 2026-09-16. The assessment is Unseen's; the terms above are the vendor's.
