Fill A Form AI
Fill A Form AI is a Chrome extension and API platform that auto-fills online forms with one click. The Sidekick extension detects form fields on any website and populates them using data from your past submissions, so you spend less time on repetitive data entry.
The tool learns from previously filled forms and can pull answers from your stored data rather than simple copy-paste. It supports Google Sheets integration for syncing form data, shared form libraries for teams, and dynamic content suggestions as you fill fields.
Fill A Form AI is built by Daybook Labs Inc. and also offers API access for developers who want to automate form filling in their own workflows. Over 1,000 users have joined, and the product launched on Product Hunt.
