NoReply vs DoNotPay: which AI actually helps a UK complaint?
DoNotPay made its name in the US as 'the world’s first robot lawyer' - a claim the FTC later fined it over. NoReply takes a narrower, more honest job: write the UK complaint letter, cite the UK law, name the right ombudsman. Here’s the fair comparison.

The short version
DoNotPay is a US product with a broad reach and a regulatory dust-up behind it - fine if you’re American and want a jack-of-all-trades assistant you’ll double-check. But a UK complaint lives or dies on UK law and the right ombudsman, and that’s what NoReply is built for, in pounds, with no pretence about being a lawyer. If you’re complaining to a British company, the home-turf tool wins.
NoReply vs DoNotPay - side by side
Where it’s built for
NoReply
The UK. Every letter is grounded in UK law - Consumer Rights Act 2015, UK261, Section 75, GDPR - and points at the right UK ombudsman or ADR scheme.
DoNotPay
The US. DoNotPay was built around US small claims, US parking tickets and US subscription cancellations. UK consumer law is not its home turf.
Pricing model
NoReply
The letter is free, and you can send it yourself. £9.99 a case (£4.99 on your first) has NoReply send it, bring their replies back onto the case and chase if it stalls. Or £29 a year (£14.50 the first year) for every case.
DoNotPay
A recurring subscription billed in US dollars. You pay to keep access whether or not you have a live complaint.
How the letter is generated
NoReply
AI reads your description and uploaded evidence, identifies the relevant UK law and drafts a personalised letter, free. Send it yourself, or have NoReply send it and track the replies.
DoNotPay
AI generates letters and forms across a broad grab-bag of tasks. Breadth is the pitch, not UK complaint depth.
What it claims to be
NoReply
An AI that writes complaint letters grounded in consumer law. We’re not a law firm and we say so plainly.
DoNotPay
Marketed for years as 'the world’s first robot lawyer' - a claim that landed it in front of the US regulator.
Regulatory record
NoReply
None. New product, launched 2024, no enforcement history.
DoNotPay
The US FTC finalised an order in February 2025 requiring DoNotPay to pay $193,000 and barring it from advertising that its service performs like a real lawyer without evidence to back it up.
Coverage
NoReply
Everyday UK and EU consumer disputes: shopping and deliveries, flights and trains, broadband and mobile, energy and water, subscriptions and services. Not financial services, personal injury, housing disrepair, employment, criminal injury or benefits claims - those are regulated, so we point you to the free route (the Financial Ombudsman, Acas, Shelter, CICA, Citizens Advice) instead. Plus 60+ free tools for tax, refunds and rights.
DoNotPay
Wide but US-centric: fighting parking tickets, cancelling subscriptions, drafting US legal documents and more.
Best for
NoReply
Anyone in the UK who wants the actual letter written, with UK law cited, in under five minutes.
DoNotPay
US users who want a broad AI assistant for everyday admin, and who’ll verify anything law-related themselves.

Built for the UK, not ported from the US
This is the difference that matters. A complaint only works when it names the right law and the right redress route. In the UK that means the Consumer Rights Act 2015, the Consumer Contracts Regulations, UK261 for flights, Section 75 for card purchases, and the specific ombudsman that covers the sector - Financial Ombudsman, Energy Ombudsman, Communications Ombudsman, and so on. DoNotPay’s playbook was written for US courts and US agencies. NoReply’s is written for the UK system it’s actually going to be used in.
What the FTC actually found
In September 2024 the US Federal Trade Commission charged that DoNotPay’s 'robot lawyer' could not deliver on its marketing, and that the company had not tested whether its AI matched a human lawyer or hired attorneys to check its legal outputs. The finalised order, approved in February 2025, requires $193,000 in monetary relief, notice to subscribers from 2021 to 2023, and a ban on unsubstantiated 'AI lawyer' claims. We’re not raising this to dunk on a competitor - it’s the clearest reminder in the industry that a complaint tool should tell you exactly what it is. NoReply writes strong, law-cited letters. It is not a substitute for a solicitor, and we never pretend otherwise.
“A complaint tool’s most important feature is telling you exactly what it is. We write the letter and cite the law. We are not your lawyer, and we’ll never pretend to be.”
