Fillsnap

AI-powered form filling assistant with local-first profile privacy.

Fillsnap is an AI-powered form filling assistant that fills any web form in seconds using your saved profile data. Whether it's a contact form, checkout, signup page, job application, or government form — just right-click and let Fillsnap handle it. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHY FILLSNAP ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Typing the same information into every form is a waste of your time. Built-in browser autofill works on obvious fields but fails the moment a form has custom dropdowns, split phone inputs, foreign languages, or anything non-standard. Fillsnap uses AI to understand the meaning of every field on a page — not just its HTML name — so it can fill forms that traditional autofill can't touch. Create a profile once. Fill anywhere. That's it. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ HOW IT WORKS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 1. Set up your profile with your name, email, phone, address, work info, and anything else you want Fillsnap to fill in. 2. Visit any page with a form you want to fill. 3. Right-click the page and choose "Fill with Fillsnap ⚡", press Alt+F, or click the extension icon and hit Fill. The form fills in a couple of seconds. Review the values before you submit — you're always in control. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ SMART FORM UNDERSTANDING ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Fillsnap doesn't just match field names. It reads each form's structure and figures out what goes where using six intelligent strategies: • Direct — one profile field maps to one form field (your name goes into the "Name" box) • Select — picks the right option from dropdowns, even custom comboboxes and searchable selects • Split — breaks one value into multiple fields when needed (extracts "+90" from your phone number into a country code field; splits "Jane Doe" into first and last name) • Combine — merges multiple profile fields into one (joins street, city, and zip into a single address box) • Derive — computes values from your data (pulls your domain from your email) • Skip — intelligently refuses to fill sensitive fields (more on that below) This means Fillsnap handles text inputs, emails, phone numbers, dates, dropdowns, custom comboboxes, radio buttons, checkboxes, textareas, address fields, country selectors — even forms built with React, Vue, or custom web components using Shadow DOM. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ MULTI-LANGUAGE SUPPORT ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Traveling, moving, or dealing with a foreign signup? Fillsnap auto-detects the form's language and translates your profile data to match. Your English profile fills Spanish registration forms, German checkouts, Turkish government applications, French contact forms — without you manually translating anything. Currently works across most major European and Asian languages. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ SAFETY — WHAT FILLSNAP WILL NEVER DO ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ You stay in charge. Fillsnap automatically refuses to: • Fill password fields (always skipped — passwords are not Fillsnap's job) • Auto-check consent, terms of service, or privacy policy checkboxes (you must read and agree yourself) • Fill CAPTCHAs or human-verification challenges • Fill file upload inputs • Submit forms for you — you always review and click submit After a fill, you can undo it with one click and restore the page to exactly how it was before. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PROFILES BUILT FOR REAL LIFE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Keep multiple profiles for different contexts — personal, work, a family member, a side business — and switch between them with one click. Each profile includes 50+ built-in fields organized into logical groups (basic info, contact, address, work, education, documents, social, emergency contact). Add unlimited custom fields on paid plans. Give each profile a color, an icon, and optional notes/memories so Fillsnap can make smarter context-aware fills based on your specific situation. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PRIVACY — HOW YOUR DATA IS HANDLED ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Let's be clear and honest about this — it matters. Your profile data is stored locally in your browser. Nothing is uploaded anywhere until you try to fill a form. When you fill a form, Fillsnap sends two things to our AI: the form's structure (the field labels and types) and your profile values. This lets the AI make precise decisions — picking the right country from a dropdown, formatting your phone number correctly, selecting your birth date in whatever format the form expects. Your data is used only for that single fill request and is never stored, logged, or sold. We don't build a profile of you on our servers. Prefer to be more cautious? Switch on Enhanced Privacy Mode in settings. In that mode, only field names (like "first_name" or "email") are sent to the AI — never your actual values. Matching happens locally on your device. You trade a bit of accuracy on tricky dropdowns and custom formats for extra privacy. Cloud sync across devices is optional, off by default, and available on paid plans. When enabled, every field is encrypted with AES-GCM on your device using a key that only you hold — we can't read your synced data even if we wanted to. You decide what sites Fillsnap works on. Use the built-in blocklist to exclude specific sites (or entire subdomains), or switch to allowlist mode to restrict Fillsnap to only the sites you approve. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ THREE WAYS TO FILL ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Right-click anywhere on a page → "Fill with Fillsnap ⚡" • Press Alt+F on any page with a form • Click the Fillsnap icon in your toolbar, pick a profile, hit Fill No intrusive floating buttons.
