Fill All: Generating E2E Tests and Automating Forms with Gemini Nano & TF.js

The Community Fill All was built for developers and QA engineers who spend their days filling out forms with locally valid data during testing and development. Every timezone, every locale, every country has its own data formats — CPF, CNPJ, RG, ID numbers, postal codes, phone numbers with regional codes — and most form-fillers don't understand them. Standard auto-fill tools generate random strings or default to a single region's formats. Developers and QA engineers end up manually calculating valid check digits, hunting for correct postal code ranges, or switching between multiple generator websites. This happens dozens of times per sprint, across different environments and locales. Fill All gives you a single, privacy-first tool that understands data validation natively — whatever your region — and goes further by using on-device AI to intelligently classify form fields without ever sending data to external servers. The project is fully open source (MIT) and welcomes contributions fr
