SEED — Form Prefill Buttons

Create manual domain-scoped buttons that prefill multiple fields.

SEED lets you create manual prefill buttons for the websites you use every day. One click fills multiple form fields at once — no typing the same values over and over. HOW IT WORKS 1. Open the SEED side panel on any website. 2. Click "New" and give your button a name. 3. Click "Add Field", then click an input on the page. 4. Set the value you want, and repeat for more fields. 5. Save. Next time you visit, click the button and every field fills instantly. FEATURES • One button fills multiple fields at once • Buttons are scoped per domain — you only see presets for the site you are on • Custom names for every preset • Runs in the Chrome Side Panel, so it stays open while you work with the page • Generate preset variants with on-device AI (Chrome's built-in Prompt API) — no data leaves your browser PRIVACY FIRST • Fills only when you click — nothing runs automatically on page load • All presets are stored locally in your browser (chrome.storage.local). No account, no server, no sync to the cloud • Site access is requested per website, only when you first pick or fill fields • No analytics, no tracking GOOD TO KNOW • SEED does not auto-fill on page load by design • Cross-origin iframes are not supported • If a website redesigns its forms, you may need to re-pick fields • SEED does not bypass CAPTCHAs or anti-automation measures Perfect for testers filling the same forms repeatedly, support agents entering standard responses, developers working with staging environments, or anyone tired of retyping the same data.
