Is your home paying too much property tax?
Type your address into your AI assistant. In seconds, see if your bill is fair, what you could save, and how to appeal.
😩 The problem
Your tax bill is a guess about your home
Counties value thousands of homes at once with mass-appraisal models. Some homes end up valued above what they'd actually sell for, and their owners pay for it every year.
2
"Is this even fair?"
Your neighbours might pay less for a similar home. There's no easy way to compare.

Appeals feel like a maze
Forms, deadlines, and "comparable sales". Most people never try, even when they'd win.
What if you could just ask? 💬
✨ The solution
Ask your AI. Get a straight answer.
Property Tax Check plugs into Claude and ChatGPT. It reads public records and Census data, so you don't have to.

In Washington DC and Philadelphia, that's all it needs. Elsewhere, add the yearly tax from your bill.
2. We compare
Your county's value vs. what the home would sell for, and your tax rate vs. your neighbours'.
3. Get your answer
A clear verdict, a rough yearly saving, missed exemptions, and help preparing an appeal if you want it.

⚠ Likely overpaying
The city values your home above your $300k estimate. If you won an appeal down to that value, you'd pay about $680 less a year.

🤔 Questions
Good to know
Is it free?
Yes. The check is free and uses public data: county assessment records and the US Census Bureau's American Community Survey.
Do you keep my address?
No. We count usage to improve the service, but we only keep the ZIP code and county, never the street address. If you ask for appeal help, we keep the name, email, phone and address you choose to share, only to contact you about your appeal. To have them deleted, reply to any email we send you.
How accurate is it?
It's a first check, not a formal appraisal. It works best when you give a realistic sale value for your home: a recent purchase price, an appraisal, or similar nearby sales. Neighbourhood figures come from Census survey data, which is an estimate.
Is this tax or legal advice?
No. It tells you whether an appeal looks worth exploring. Appeal rules and deadlines differ by county, so check with your assessor's office before you file.
What's an exemption?
A discount on your taxable value, for example a homestead exemption for the home you live in. They're easy to miss, and claiming one is often quicker than an appeal.
