How it works · Tax notice
Redact tax papers, then ask Ai about your taxes
Cover takes your identity out of your tax papers before Ai sees them. The numbers stay, so Ai can still tell you what the IRS wants.

- 1099s
How it works
Stop leaking your identity to Ai
Drag the tax notice into Cover, then drag the redacted copy into your Ai chat. It answers with labels where the private details were.
Animation: IRS letter.pdf is dragged into Cover, which replaces each private detail on the page with a label (ADDR_1, NAME_1, SSN_1). The redacted copy is dragged into an Ai chat with a question, and the Ai answers using the labels.
The tax notice as the Ai receives it, IRS letter-redacted.pdf: Department of the Treasury Internal Revenue Service Notice CP2000 Tax year 2025 [NAME_1] [ADDR_1] Cupertino, CA 95014 Your SSN [SSN_1] We propose changes to your 2025 tax return Refund you claimed $2,525 → Revised refund $2,140 Income you reported $84,210 Income reported to us $85,960 Tax change +$385
Question: Should I have gotten a bigger refund this year?
The Ai's answer: [NAME_1] reported $1,750 less income than the IRS has on file, so the refund drops by $385.
Try it on your own document: drop a PDF into Cover for Web and see what it redacts.
Ask Ai
Tax answers from Ai, without your identity or your client's
Turn on Tokens and each redaction carries a label like [NAME_1] or [SSN_1], the same on every page. The Ai can still tell one person from another and answers with the labels. It works from the labels, not the real details.
Why does the IRS say I owe more?
The notice says the IRS has $1,750 more income on file for [NAME_1] than the return reported, from a 1099 that wasn't included. That raises the tax by $385.
What changed from last year's return?
[NAME_1]'s wages rose about $6,000, but withholding stayed almost flat, so the refund shrank even though the tax rate did not change.

What it removes
What Cover removes from your tax papers
Cover finds these on its own and redacts them:
- Names of the taxpayer and spouse
- Social Security numbers, masked ones too
- ITINs
- Employer and payer EINs
- Addresses
- Phone numbers
- Email addresses
The numbers stay readable, which is what the Ai needs to check the math. You check every page in the editor before you save.

Questions
Can ChatGPT explain an IRS notice without my Social Security number?
Yes. It needs the figures, and those stay. Only what identifies you or your client comes out.
Does Cover remove the SSN or just hide it?
It removes it. The characters come out of the file, so copying or searching the PDF finds nothing.
Is the Ai's answer right?
Not always. It's the Ai's own reading, so check anything you act on with the IRS or a tax professional.
