How to use AI to understand a confusing letter, step by step

You open the envelope, read the letter twice, and still aren’t sure what it means. Maybe it’s your bank describing “changes to your account terms.” Maybe it’s a hospital letter full of medical words. Maybe your landlord has written about a “rent review” and a “notice period.”

An AI assistant can help you work out what a letter says, what it might be asking you to do, and what to ask the people who sent it. It can’t tell you for certain what the letter means for you, and it isn’t a replacement for your bank, your doctor or a housing adviser. Used carefully, though, it can turn a stressful letter into a clear to-do list.

Step 1: Take out your personal details first

Before you copy anything into an AI tool, remove anything that identifies you or your accounts. What you type into an assistant may be stored, and depending on your settings it may be reviewed or used to improve the service. Treat it like a conversation in a public place.

Delete or replace:

• Your name, address, phone number and email
• Account numbers, sort codes, card numbers, policy or reference numbers
• Dates of birth, national insurance or social security numbers
• Patient or hospital numbers, and the names of your doctors
• Your landlord’s or letting agent’s name and the property address

Replace them with simple placeholders, such as [MY NAME], [ACCOUNT NUMBER] or [PROPERTY ADDRESS]. The AI doesn’t need the real details to explain what the letter means.

If the letter is a photo or scan, be extra careful. Many assistants let you upload images, but an image carries everything on the page, including letterheads, barcodes and reference numbers. Photos taken on a phone can also carry hidden details, such as where the photo was taken. Typing the important paragraphs in yourself is usually safer. Or cover the personal parts before you take the photo.

If you do retype the letter, check what you typed against the original before you paste it in, especially numbers, amounts and dates. If you make a mistake while copying, the AI will explain your mistake, and you may not spot it later.

For medical letters, think about whether you need to share the diagnosis wording at all. Even without your name or numbers, a rare condition combined with dates or places can still point to you. Sometimes you only need help with one or two terms, and you can ask about those on their own.

Step 2: Ask for a plain-English explanation

Paste the cleaned-up text and ask for a simple summary. Here’s a prompt you can adapt:

I received this letter from my [bank / doctor's surgery / hospital / landlord].
I've removed my personal details. Please explain it in plain English, as if
to someone with no background in [banking / medicine / housing law].

Tell me:
1. What the letter is about, in two or three sentences
2. Whether it's asking me to do anything, and by when
3. Any words or phrases that might be confusing, with simple explanations

Here's the letter:
[PASTE LETTER TEXT]

If one part is still unclear, ask about just that part:

In the letter, it says "[PASTE THE CONFUSING SENTENCE]".
What does this usually mean? Explain it simply, and tell me if it could
mean more than one thing.

That last line matters. It encourages the AI to admit uncertainty instead of picking one meaning and sounding sure about it.

Step 3: Find the deadlines and actions

Letters often hide the important part: something you have to do, and a date to do it by. Ask the AI to pull those out clearly.

Based on this letter, make a short checklist of:
- Anything I need to do
- Any deadlines or dates mentioned (quote the exact wording)
- Anything that happens automatically if I do nothing

If the letter doesn't say something clearly, tell me that rather than guessing.

Asking it to quote the exact wording means you can check every date against the original letter yourself.

Watch out for dates written as numbers. 03/04 means 3 April in the UK but March 4 in the US, and an AI can easily read it the wrong way round. Read the date in the original letter yourself, and if it could go either way, tell the AI which format your country uses.

Step 4: Get questions to ask the sender

This is often the most useful step. A good list of questions makes a phone call or appointment much less stressful.

I need to contact [my bank / my GP / the hospital / my landlord] about this
letter. Suggest 5–8 clear, polite questions I could ask to make sure I fully
understand what it means for me and what my options are. Put the most
important questions first.

You might get questions like “Does this change affect the interest I pay?”, “Is this test result something I need to act on before my next appointment?” or “What happens if I can’t agree to the new rent?”

You can also ask the AI to help you write a reply:

Help me write a short, polite [email / letter] to [the sender] asking them to
clarify [the specific point]. Keep it under 150 words and friendly in tone.
Leave [brackets] where my personal details should go.

Fill in your real details yourself, in your own email program, after the AI has finished.

Watch out for

AI assistants are good at explaining language, but they make mistakes. Here’s what to look for:

• Confident but wrong answers. An assistant can sound certain even when it has misread something. Check every key point against the original letter.
• Rules that differ by place. Tenancy rules, banking rules and healthcare processes vary a lot between countries, and even between regions. The AI may describe the general picture, or rules from somewhere else. Tell it your country or region (not your address), and still treat its answer as a starting point.
• Missing context. The AI only sees what you paste. It doesn’t know your contract, your medical history or earlier letters, so it can’t know how the letter applies to you.
• Made-up details. Sometimes an assistant fills a gap with something that isn’t in the letter. If it mentions a figure, date or condition, find it in the original. If you can’t, ask: “Where in the letter does it say that?”
• Reassurance it can’t give. If a medical letter worries you, an AI saying “this is usually nothing serious” doesn’t mean it’s nothing serious for you. Only your doctor can tell you that.

Always confirm with a professional

Use the AI to understand the letter and prepare. Then check what matters with someone who knows your situation:

• Bank letters: call your bank on the number printed on your card or official statement. Don’t use a number from the letter itself if you have any doubt it’s genuine. If the letter asks you to share passwords or move money urgently, treat it as a possible scam.
• Medical letters: ask your doctor, nurse or the hospital department that sent it. Bring your list of questions.
• Landlord letters: if the letter is about rent increases, repairs or ending a tenancy, a local housing advice service or tenants’ organisation can tell you your rights where you live.

Some letters can’t wait. If a letter mentions a court, eviction or possession, debt recovery, or a deadline to appeal or respond, get advice quickly. Free legal advice and debt advice services can help. These letters often have short, strict time limits, so don’t wait on the AI’s summary, and don’t let a deadline pass while you work out what the letter means.

A confusing letter doesn’t have to ruin your afternoon. Remove your details, ask for a plain explanation, pull out the deadlines, and walk into the next conversation knowing what to ask.
