OneTap: Checkout Autofill & Form Filler for Any Site

AI-powered checkout autofill & form filler. Save your address, card & contact details once — fill any checkout form in one tap.

Tired of typing the same name, address, and card details on every single checkout page? OneTap fills them all in one click. Save your shipping, billing, and payment profiles once. When you land on a checkout page, tap the bolt — every field fills instantly. Name, email, phone, address, card number, expiry, CVV. Done. OneTap uses AI to detect form fields across any website, even the weird ones where Chrome's built-in autofill breaks. Split card fields, non-standard address layouts, multi-step checkouts — OneTap handles them. Your data stays on your device. Cards and personal details are encrypted with AES-256 and stored locally — nothing is uploaded to a server, nothing is sold, nothing leaves your machine. Unlock with Touch ID or your master password each session. Features: - One-click checkout autofill across any site - AI-powered field detection that works where browser autofill fails - AES-256 encryption, stored locally on your device - Touch ID / biometric unlock - Multiple profiles for different addresses or cards - Locks automatically when you quit Chrome Free to use. No account required. No data collection.
