Deft — Autofill Signup Forms Privately

Deft fills out signup forms for you. Paste your details once. From then on, a button appears on any registration form — click it and Deft writes your name, date of birth, email, phone and address into the right fields, picks the right options in dropdowns, and generates a strong password that matches the site's own rules. YOUR DETAILS STAY ON YOUR DEVICE Most autofill tools send your personal information somewhere to work out what goes where. Deft doesn't. It identifies fields by reading the form's own labels and attributes — never your data. Most forms it recognises instantly, offline, with no network request at all. For unusual forms it can ask a language model for help. Even then it sends only the form's field names — never your name, your date of birth, or anything else about you. WHAT IT WILL NOT DO • Never submits a form for you • Never ticks consent, terms or marketing checkboxes — those are yours to decide • Never fills payment details, CAPTCHAs or one-time codes • Never stores or fills existing passwords • Leaves anything it isn't confident about blank, and tells you it did THE FIDDLY PARTS IT HANDLES • Dates in whatever format the site demands — dd-mm-yyyy, ISO, or three separate dropdowns • "Confirm email" and "confirm password" matched to what they confirm • Dropdowns matched on meaning, so VIC finds "Victoria" • Phone numbers reformatted to suit each field • Passwords built to the site's own stated character rules AFTER EVERY FILL A review panel shows what was filled, what was left for you, and why. Nothing is submitted until you have looked at it. Free, and no account required. The optional model fallback runs on Chrome's built-in on-device AI where available, or on your own OpenRouter API key — Deft does not resell AI access.
