What Merlin is
Merlin is built around invoking AI from any tab to summarize, rewrite, research, and chat with source material. Its broad marketing claims call for careful distinction between publisher descriptions and independently verified behavior.

Permissions and privacy
Page access
Its ability to read pages and files should be matched with cautious site-access settings and school data rules.
Data notes
The Chrome Web Store lists personally identifiable information and location among handled data categories.
Pricing
Free limited access; paid plans and in-app purchases. Pricing and plan limits change more often than store metadata, so use the linked developer page as the final check before subscribing.
