An AI-powered browser extension that stores your information once and intelligently auto-fills forms across any website.
Superfill.ai is a cross-browser memory extension that eliminates repetitive data entry by creating an intelligent memory layer. Using AI-powered categorization and matching, it understands form context and provides accurate, relevant answers across job applications, dating sites, rental forms, surveys, and more.
Current Status: Phase 1 is complete! Core memory management and AI auto-fill features are live but only for input & textarea fields. Phase 2 (in progress) will add advanced features like select/radio/checkbox/date/async selection options support, alternate fill modes, Safari support, and premium cloud sync features one by one.
