Watch how it worksA few practical details about
your new form-filling shortcut.
Founderfill can suggest straightforward details like your startup name, website, and founder information, reuse saved responses, and draft answers to open-ended startup questions with AI. It’s designed for relevant fields in directory listings, applications, profiles, and other regular website forms.
You don’t have to keep finding the same information in your notes, asking an AI chat to rewrite your pitch, or moving answers between tabs. Founderfill prepares a suggestion in the field itself. You review it and click to use it. The extension also shows estimated time saved as you fill; actual savings depend on your workflow.
No. Preparing suggestions never changes the page. A field is filled only when you click Fill or Replace, and you can edit or undo that change. Founderfill never submits forms, accepts terms, makes purchases, or posts messages for you.
Your profile is stored locally in the extension, with account-based cloud sync for regular profile facts and approved memories. Contextual AI requests use relevant profile information. Sensitive facts have separate controls for local use, sync, AI, and filling; sensitive sync and remote AI are off by default. Read about privacy.
Founderfill is built for desktop Google Chrome, version 116 or newer. It works with relevant form fields on regular websites, including many dynamic forms. Some custom editors and protected browser pages may not be supported. You can pause it or block individual sites whenever you like.
Founderfill will be available to install from the Chrome Web Store. The listing is coming soon. In the meantime, explore the interactive demo to see how it works. Watch the demo.
