About FlashFill

───────────────────────────────────── WHAT FLASHFILL DOES ───────────────────────────────────── The moment FlashFill detects a signup or registration form on any page, it: Generates a complete burner identity — real-looking name, a working temporary email address, username, password, and phone number Ghost-fills the entire form instantly — you don't touch a thing Watches the inbox in the background while you wait The second the verification email lands, it extracts the OTP and injects it directly into the code field — automatically Start to verified in under 10 seconds. Zero clicks required. ───────────────────────────────────── FEATURES ───────────────────────────────────── ⚡ AUTONOMOUS FORM DETECTION FlashFill monitors every page you visit and recognises signup, registration, and login forms automatically. No button to press, no configuration needed. When it sees a form it can fill — it fills it. 📬 REAL WORKING TEMP EMAIL Every identity comes with a fully functional temporary email address. Verification emails actually arrive. FlashFill reads them so you don't have to. 🔑 AUTOMATIC OTP INJECTION When a verification code email arrives, FlashFill finds the code inside it (even in complex HTML emails full of images and styling), then locates the OTP input field on the page and types it in — no copy-paste, no tab switching. 🔗 MAGIC LINK SUPPORT Some sites send a "click to verify" link instead of a code. FlashFill detects those too and surfaces a one-click VERIFY button right in the popup so you never have to dig through your inbox. 📋 LIVE INBOX IN THE POPUP Open the FlashFill popup at any time to see your burner inbox. Every email is listed with sender, subject, and a COPY button for the code — or a VERIFY button for magic links. One is always shown, never both, so there's no confusion about what to do. 🕵️ COMPLETE BURNER IDENTITY Each generated identity includes: • A temporary email address • First and last name (realistic, not gibberish) • A username • A strong password • A US phone number Everything you need to complete any signup form without using your real details. 📖 IDENTITY HISTORY & NAVIGATOR FlashFill remembers your past burner identities. Switch between them using the ‹ › navigator in the popup. Useful when you've signed up for multiple services and need to revisit a previous email address. 🔔 PENDING OTP BANNER If FlashFill couldn't auto-inject the code (for example, you navigated away before the email arrived), a bright banner appears at the top of the popup the moment the code lands — so you can copy it with one tap and never miss it. ⏸ PAUSE / RESUME Not every form should be auto-filled. Hit the pause button to stop FlashFill from touching anything on the current session. Resume when you're ready. ───────────────────────────────────── WORKS ON ───────────────────────────────────── FlashFill seamlessly automates OTPs and burner emails across your favorite productivity tools, design platforms, SaaS products, and workspace environments. It works on virtually any website that uses a standard email + OTP or email + magic link verification flow — which covers the vast majority of modern signup forms. ───────────────────────────────────── WHO IT'S FOR ───────────────────────────────────── → Developers and designers who trial new SaaS tools constantly and don't want their real inbox spammed forever → Researchers and testers who need to create accounts repeatedly without revealing personal information → Anyone who's tired of the signup-verify loop eating 2 minutes of their life every single time → Privacy-conscious users who don't want every app they try knowing their real email address ───────────────────────────────────── PRIVACY FIRST ───────────────────────────────────── FlashFill never reads, stores, or transmits the content of the real pages you visit. It only activates on signup forms you're already filling out. Your real identity, browsing history, and personal data are never touched. The burner email addresses and identities it generates are completely disposable — there is no connection to you whatsoever. ───────────────────────────────────── FREE TIER ───────────────────────────────────── Get started with 2 free burner identities — no credit card, no account required. A paid tier with unlimited identities is coming soon. ───────────────────────────────────── Stop filling out signup forms. Let FlashFill do it.
