How it works

From the ticket in your hand to a finished letter

Four steps, about a minute. You need the notice itself and nothing else — no account, no payment, and no legal knowledge.

How it works

Step 01

Describe your ticket

Upload a photo or fill in the form.

Step 02

We analyse your case

Cato weighs your grounds against past decisions and your authority's own figures.

Step 03

Get your appeal letter

Confirm what evidence you have, then get a letter written around your case.

Step 04

We follow up with you

Once you have created your account, we remind you when to chase a response, and you track the outcome in My Appeals.

Not just a chatbot

Matched to precedent

Based on legal precedent and the most successful arguments, allowing Cato to significantly outperform generic AI models.

Every citation verified

A separate check confirms every law and case cited is real and correctly applied, so nothing invented reaches your letter.

Jurisdiction-aware

England, Wales and Scotland run different rules, and private car parks a different code again. Cato applies the right one. Northern Ireland isn't covered yet.
