Is ChatSider AI Copilot : ChatGPT & Claude safe?

Clean risk

ChatSider AI Copilot sends search queries and selected page text to the ChatsNow GPT endpoint.

When you use its search assistant, the extension reads the query from supported search result pages and sends it to ChatsNow's GPT API. It also runs on all sites and can send text you select on a page when you click one of its quick-action assistant buttons.

Shared hosts - 2 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.
