Find what you are still paying for. Then stop.

SubKiller works inside your AI assistant. Your assistant looks through your email receipts, and SubKiller turns them into a clean list: what you pay for, what each costs a year, and how each one is really cancelled. Your list builds up month after month. Free.

How it works

1. Your assistant searches your inbox, with your permission. Receipts, renewal notices, trials about to convert, price increases. SubKiller never sees your email.
2. You get the list, with the yearly cost of each. Most people find a few they forgot. You decide what stays.
3. It shows how to cancel each one, and how hard that will be. Some take a few clicks. Some are a maze of offers. Some only cancel by phone, in person or by letter, and SubKiller says so plainly. When it has to be a message, it drafts one and your assistant sends it from your own email after you approve it.
4. It checks the charge actually stopped. A cancellation counts when the charge stops showing up, not when the company says so. Next month your assistant looks again.

Add SubKiller to your assistant

It works with Meta's Muse and any assistant that supports connectors (MCP servers) and has access to your Gmail or Outlook. No account and no key. Add a custom connector with this address:

Then say: Find the subscriptions I am paying for and help me cancel the ones I do not use.

What it does not do

SubKiller finds, explains and drafts. It does not log in to your accounts or cancel anything by itself. It is not connected to Apple or Google: it finds the subscriptions they bill from the receipts they email you, and the complete list is always in Settings on your own phone. Anything that never sends a receipt to your inbox, such as a gym draft from your bank account, will not show up until you add it.

Honest about what it knows

SubKiller knows 646 of the most common services so far, and the list grows as people use it. For 292 of them it links the company's own cancellation page, because a machine check found that page live on 2026-09-21. For the rest it gives the steps in words and says the link was not checked. It never presents a guess as the cancel page.

What it stores

Your saved list holds merchant names, amounts, dates and a status for each. It is kept under a random key that only you and your assistant have. There is no name, email address, card number or email content in it, and you can delete it any time. The list opens from a private link, and anyone who has that link can see it, so keep it to yourself. A list that goes 12 months without an update deletes itself. Details are in the privacy policy and the terms.
