How to audit your subscriptions (and negotiate bills) with an AI agent

Not yet tested by us. This is a how-to, not a case study: we haven’t measured results for this workflow yet. When we do, we’ll show the numbers.

Subscriptions are easy to start and easy to forget. An AI assistant is good at the tedious part: reading through months of statements, spotting the charges that repeat, and drafting the “please cancel” or “can you do better on price?” message. You stay in charge of the accounts and the decisions.

Step 1: Gather your statements, with the sensitive parts removed

Download the last few months of bank and credit card statements as CSV or PDF. Before you share anything with an AI tool:

• Remove or mask full account and card numbers.
• Never share passwords or one-time login codes.
• If your AI tool can connect to accounts directly, decide carefully what access you’re comfortable giving it. Read-only beats full access.

Step 2: Ask the AI to find every recurring charge

Try a prompt like this:

Here are my last 3 months of card and bank transactions. List every charge
that looks recurring (monthly, yearly or every few weeks). For each one,
give the merchant, amount, how often it repeats, and the date of the last
charge. Flag anything that changed price, appears twice, or looks like a
free trial that turned into a paid plan. Don't guess what a charge is if
you're not sure; mark it "unknown" so I can check.

Check its list against your statements. AI can misread merchant names or miss yearly charges that only show up once.

Step 3: Sort into keep, cut and negotiate

Go through the list yourself. For each item ask: do I use this? Would I notice if it were gone? Is there a cheaper plan? Do I pay for the same thing twice (two streaming services, two cloud storage plans)?

You can ask the AI to help you think it through, but the decision is yours.

Step 4: Have the AI draft the messages

For things you’re cutting:

Draft a short, polite message canceling my [service] subscription,
account email [your email]. Ask them to confirm the cancellation in
writing and tell me the date my access ends. Don't include any
payment details.

For bills you want to lower (internet, phone, insurance, software):

Help me prepare for a call or chat with [provider] to lower my bill.
I pay [amount] a month for [plan]. Give me a short script: what to
ask for, polite ways to mention I'm comparing options, and what to do
if they say no. Keep it honest; don't make up competitor offers.

Step 5: You send it, or approve it

Send the message, make the call or click cancel yourself. If you use an agent that can act on your behalf, set it to ask before every cancellation or account change. Watch out for:

• Annual plans that don’t refund unused months
• Cancellation deadlines before the next billing date
• Services bundled with something you want to keep

Step 6: Keep a simple savings log

For every change, write down the date, the service, the old price, the new price (or $0) and any confirmation number. That’s how you’ll know your real savings, rather than an estimate. If an AI subscription or app costs you money, subtract that too. Then check next month’s statement to make sure the charge actually stopped.

Honest caveats

• We haven’t tested this yet. We’ll publish real results once we’ve run it. A comparison of cancellation agents is planned, and we’ll publish it once we’ve run the tests.
• AI can be wrong about charges. Always confirm against your statements.
• Negotiating doesn’t always work. Some providers won’t budge. That’s fine; you’ve still learned what you pay.
• Mind the privacy trade-off. The less account access you hand over, the less can go wrong.
