Is Cluing - AI Knowledge Base safe?

Low risk

Cluing reports page URLs, titles, and reading engagement metrics for visible text blocks to account.cluing.io.

When you visit pages, Cluing's highlighter content script creates a document record with the page URL and title. It tracks visible text blocks and sends engagement data such as dwell time, focus clicks, copy counts, and text hashes to Cluing's servers every few seconds.

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

Shared hosts - 12 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.
