Questions.

Does Fillr work on React / Vue / Angular apps? +
Yes. Fillr uses the native input value setter (bypassing React's synthetic event system) and fires focus → input → change → blur events. This triggers reactivity in all major frameworks. Shadow DOM and dynamically injected modals are supported too.
What counts as an AI fill? +
Only fills that make a Groq API call (the "Fill with AI" button or Alt+Shift+F). Template fills, random fills, and edge-case fills are fully local - they don't count against your weekly limit, ever, even on the free plan.
Can I use Fillr on sensitive internal tools? +
Fill data is generated server-side and sent directly to your browser - never stored on Fillr's servers. You can block Fillr on specific pages or domains using the "Hide on this site" option in the panel. Password fields are filled but never logged anywhere.
