Is Definio AI: Multi-Modal AI Sidebar safe?

Medium risk

Definio AI can send selected page text, screenshots, and account identifiers to Definio and analytics endpoints.

When you use its sidebar chat, the extension can include selected text from the page along with the page URL and title in requests to ai.definio.org. If you trigger screenshot capture, it uploads active-tab images to ai.definio.org; authenticated users are also identified to api.analytics.dterm.ai with account and install identifiers plus browser/device context.
