— HOW IT WORKS —

Three steps. Ninety seconds.

You forward a document. ShieldEngine™ reads it. You send the response. That’s the whole thing — and most of what happens after is automatic too.

01

Forward your document.

Email any bill, contract, collection letter, or suspicious notice to your personal [email protected] address. Or drag and drop it in the dashboard.

What works: PDFs, photos of paper bills, forwarded emails, screenshots. If you can read it, we can read it.
02

ShieldEngine™ reads every line.

Sunny routes your document to the right specialist — medical, debt, contracts, travel, scams, or home & auto. That specialist reads it line by line against the relevant benchmarks and laws.

How long: About 90 seconds for most documents. You can watch it happen live.
03

Send your response.

If something’s wrong, a dispute letter is already drafted for you — citing the specific line, the benchmark it fails, and the law that backs you up. Review, sign, send.

Then what: When they reply, ReplyShield™ reads it and drafts your next letter automatically.
+ Live

You’ll watch it happen in real time.

No spinner that says “please wait.” You see the specialist working, see findings appear as they’re caught, and see exactly what your dispute letter will say before you send it.
