Extension Metadata

About this extension
utoFill Forms saves you from retyping the same information into every signup page, form, and application you fill out.

Save your details once — name, email, phone, address, employer, job title — and click Fill this form on any page. The extension scans visible form fields, matches them to your saved profile using label text and common field-naming patterns, and fills them in automatically. Fields it fills get a subtle yellow outline so you can quickly review what changed before submitting.

For unusual or ambiguously-labeled fields the local matcher can't confidently handle, you can optionally connect a Gemini API key to let AI take a second pass — results are cached per website so repeat visits don't re-spend API calls.

What it does:

Detects fillable fields, including labels linked via aria-label, aria-labelledby, or nearby text — not just formal <label> tags
Matches fields to your profile using a synonym dictionary and fuzzy text matching
Fills fields the way real user input does, so the change registers correctly even on modern JavaScript-built forms
Shows a summary after filling: how many fields were filled, how many still need your review
Lets you clear a fill with one click

What it never does:

Never submits a form for you — you always review and submit manually
Never sends your profile data anywhere unless you explicitly enable the optional AI fallback, and even then, only field labels (not your personal values) are sent for matching
Never syncs your data anywhere — everything is stored locally in your browser

Known limitations (v1): doesn't yet support forms inside iframes, multi-step/multi-page forms, or checkbox/radio questions.
