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.
