Yes, AI can write a clear complaint or refund request from the facts you give it — but it works best as an editor, not an author. Write down the facts first, share only what is needed, check every date and amount, and never let it quote laws it cannot name.
A good complaint is short, calm and specific. That is also what most people find hardest to write when they are annoyed. AI is useful here — not because it knows more than you, but because it can turn your jumbled facts into clear paragraphs in seconds.
There is one rule behind everything below: you supply the facts, the AI supplies the wording. If you reverse that, you risk a letter that sounds confident and is wrong.
Does it actually help?
There is some evidence. Researchers at Yale studied more than 1.1 million consumer complaints sent to the US Consumer Financial Protection Bureau between 2015 and 2024. Complaints that appeared to be written with AI ended with some form of relief (money or another remedy) about half the time, compared with about 40% of the human-written ones. The researchers detected AI use with a tool that is not perfect, so treat this as a hint, not a promise.
At the same time, organisations that receive complaints are cautious. The City of Bradford Council in the UK and the Ombudsman of Western Australia both say they prefer complaints in your own words, Bradford warns that AI can add mistakes, exaggerate, or get laws wrong; the Western Australia ombudsman warns that it can introduce inaccuracies or make a complaint unclear. The Western Australia ombudsman also says it may ask you to rewrite a complaint in your own words if the AI use makes it unclear. So use AI to organise and polish, not to invent.
Write down the facts first, in plain notes
Before you open any AI tool, make a list on paper or in a note:
- what you bought or booked, and from whom
- the date, the amount and the order or booking number
- what went wrong and when you noticed it
- what you have already done (called, emailed, got a reply)
- what you want: a refund, a replacement, a repair, an apology
Five minutes spent on this is the most useful part of the whole process. The AI can only be as accurate as these notes.
Give the AI only what it needs
Chat tools may keep what you type. Paste the facts from your notes, but leave out:
- bank account and card numbers
- your national ID or passport number
- health information
- passwords and security codes
Use placeholders such as [ORDER NUMBER] and [MY NAME], and fill them in after the draft is ready. For more on what is safe to share, see our guide on using AI for legal documents safely.
Ask it to use only your facts
Here is a prompt you can copy and fill in:
Write a short, polite but firm complaint to [company]. Use ONLY the facts below — do not add details, dates, amounts or legal references that I did not give you.
Facts:
- I bought [product] on [date] for [amount], order number [number].
- The problem: [what went wrong].
- What I have already done: [contacted them on date, what they said].
- What I want: [refund / replacement / repair] within [14 days].
Keep it under 200 words, in plain language, and put what I want in the last paragraph.
The sentence "do not add details" matters. Without it, AI tools sometimes fill gaps with plausible-sounding facts.
Check every date, amount and claim
Read the draft slowly against your notes. Look for:
- Numbers and dates that changed or appeared from nowhere
- Exaggeration: "months of problems" when it was two weeks
- Legal references: "under Section X of the Consumer Act". If you did not provide it, delete it, or look it up yourself on an official site first
- A tone you would not use face to face
Then change a few sentences into your own words. A letter that sounds like you is easier for the person reading it to believe.
Send it in a way you can prove, and set a deadline
Use the company's official complaint email or form, keep a copy, and note the date. Say what you want and by when (14 days is common). Do not threaten things you will not do. Keep screenshots of order confirmations and earlier replies.
If the company does not answer
After your deadline, send one short reminder that mentions the date of your first message. If you still get nothing, most countries have a free route that does not need a lawyer:
- United States: for banks, cards, loans and similar financial products you can submit a complaint to the Consumer Financial Protection Bureau (consumerfinance.gov). The CFPB forwards it to the company, which is expected to respond within 15 calendar days.
- Elsewhere: look for your national consumer authority, a consumer ombudsman or an out-of-court dispute-resolution body. Many of them require that you first complained to the company in writing, which is one more reason to keep your letter and its date.
These bodies usually cannot force a company to pay, and procedures can be voluntary for the company. Even so, a clear paper trail makes your case easier to judge. If an AI-written letter contains something you are unsure of, our guide on why AI makes things up explains why it happens.
