Users appreciate Annotate for its ease of use on webpages, helpfulness in teaching, and cross-browser compatibility. However, major drawbacks include mandatory intrusive registration, limited free features forcing premium upgrades, and bugs causing freezing during exports. Additionally, recent updates have damaged pen responsiveness, the interface feels outdated, and toolbar usability suffers under zooming. Many reviews request improvements like better shortcut customization, more colors for free users, and fixing loading issues.

Requires way too much personal info in order to sign up for the Annotate.net account (mandatory to use the extension)! Why do you need to know my salutation, first name, last name, and birth date? For that reason, I AM OUT!!!

12 annotations on a free plan with a lackluster 1990s interface.
