The brief
Everyone with a desk job knows the ritual: the same name, address, company details and answers typed into web form after web form, with small errors creeping in every time attention drifts. AutoFyl set out to end it — a browser extension that understands any form it meets and fills it accurately from your saved details.
The hard part isn't storing data; it's recognition. Every website builds forms differently, labels fields inconsistently, and breaks conventions freely. A useful form-filler has to read a page it has never seen and work out — reliably — which field wants what.
What we built
- AI field recognition
- A recognition engine that interprets unfamiliar forms — matching fields to the user's saved details by meaning, not by hard-coded rules, so it works on sites it has never seen.
- Manifest V3 extension
- Built natively on Chrome's current extension platform: service-worker background, content scripts hardened against hostile page markup, and minimal permissions to clear store review cleanly.
- Private profile vault
- The user's details stay under the user's control — structured profiles for personal and work contexts, with the extension architected so data goes only where the user points it.
- Store launch & lifecycle
- Chrome Web Store listing, privacy policy, review process and the ongoing update discipline that keeps an installed base working as Chrome's platform evolves.
The stack
Where it landed
AutoFyl is live on the Chrome Web Store and in daily use — and it's our proof, not just our pitch. When we build extensions for clients, the store-review scars, MV3 patterns and update pipeline all come from shipping and running this product ourselves.
