Bill Buster
Feed in a confusing bill — electricity, water, phone, council rates — and get back what it actually means, what you owe, when it is due, and whether anything looks off compared to your last one.
How it works
Bills are full of line items, tariffs, and codes that are not written for a normal reader. Rather than trying to decode it yourself, you describe (or paste in) the numbers on the bill, and Claude reads it back in plain language — what the charges are for, what is due and when, and whether anything jumps out as unusual compared with a previous bill.
How to use it
- Have the bill in front of you, or a photo/PDF of it open.
- Type out the key numbers and line items, or describe what is confusing about it.
- Ask what a specific charge means, or whether the total looks right.
- If something looks off, ask what question to ask the provider, or move to Letter Writer to draft a complaint.
A few prompts to start with
Decode a confusing charge
"Here's my electricity bill: usage charges $142, supply charge $38, a 'peak demand' fee of $27 I haven't seen before, total $207. Last quarter was $164. Can you explain the peak demand fee and tell me if this increase looks normal?"
Check a bill against last time
"My water bill this quarter is $186. Last quarter it was $151 and nothing changed in my household. What are the most likely reasons it went up, and what should I check before calling the provider?"
Understand a phone or internet bill
"My phone bill has a $15 'plan adjustment' fee I don't recognise, on top of my usual $45 plan. Can you explain what this kind of fee usually means and whether I should query it?"
Get ready to call your provider
"I think I've been overcharged on my council rates notice. Can you give me three clear questions to ask when I call, and what information I should have ready?"
Copy whichever fits, swap in your own details, and paste it into Claude to get a plain-English answer written for your exact situation.
