Can I just use ChatGPT to read my letting-agent statement?

It’s a fair question, and the honest answer is: yes - once. If you paste a single, clearly typed statement into ChatGPT (or any AI chatbot) and ask for the figures in a table, it’ll usually do a decent job. So if you’ve got one statement, once a year, and time to check it, you may not need anything else.

The catch is that reading one statement was never the hard part. The hard part is everything that comes after the first one.

Where doing it yourself with AI starts to hurt

• You get a different answer each time. Ask twice and the columns, the wording, even which lines it includes can change. Across a year of statements you end up with data that doesn’t line up with itself - no good for a spreadsheet or a tax return.
• It doesn’t check its own maths. A chatbot will hand you a tidy-looking table whose totals don’t actually reconcile against the statement. It looks right, which is exactly what makes it dangerous.
• It muddles the tricky lines. Money the landlord paid in gets counted as rent; rent that’s still owed gets treated as cash received; a repair the agent paid on your behalf goes in the wrong place. These are the errors that quietly overstate your income.
• Every agent’s layout is different. The prompt that worked for one agent’s statement won’t behave the same on the next. You’d be learning prompt-wrangling instead of getting on with your records.
• You’re handing a financial document to a chatbot. Depending on your settings, what you paste may be stored or used to train the model.

What a purpose-built tool does differently

This is the gap RentSorter is built to fill. It’s not “AI reads a PDF” - you can already do that yourself. It’s the parts that have to be dependable:

• The same result every time - the same columns and the same categories on every statement, so a year’s worth actually stacks up into one consistent record.
• The maths is checked - it reconciles each statement against its own totals and shows you a green tick, or flags it if something doesn’t balance. (More on that in your statement, explained.)
• Every agent, one format - different agents’ statements all come out looking identical, with no prompting on your part.
• Nothing is stored - the statement is turned into a spreadsheet in the moment and then forgotten.

So which should you use?

For a one-off, ChatGPT is fine if you’ll check it carefully. The moment it’s more than that - monthly statements, several properties, or figures you’ll actually rely on for tax - the thing you need isn’t a cleverer prompt, it’s consistency and a maths check you can trust. That’s the difference between doing it yourself with AI and having it read for you.
