Permissions and privacy
Page access
Browser AI assistants may read the active page and selected text to generate a response. Check the current host permissions and avoid submitting private course, client, or account data.
Data notes
AI features may send prompts and page context to remote models. Treat the developer policy, model-provider terms, retention settings, and school or workplace rules as part of the product decision.
Pricing
Free Basic tier with paid Professional plans. Pricing and plan limits change more often than store metadata, so use the linked developer page as the final check before subscribing.
