zombie-killer 🧟

Find the subscriptions silently draining your bank account — and get the exact letters to cancel them, renegotiate the bill down, or erase your data.

You paste your bank/card statement (or a list of subscriptions). zombie-killer detects the recurring charges, flags the zombies (forgotten, price-crept, free-trials-that-converted, hard-to-cancel), totals your yearly waste, and drafts ready-to-send letters. You send them. It never contacts the company, never impersonates you, never acts on your behalf.

Works for people (web app) and for AI agents (MCP server + x402 pay-per-call).

What it does

Detect — parses raw transaction text (CSV export or free-form lines), groups by merchant via an embedded catalog of ~50 high-frequency subscription services (with real cancellation / privacy contacts), classifies cadence (weekly / monthly / quarterly / yearly), and scores each charge ZOMBIE / REVIEW / ACTIVE. One-off purchases (gas, groceries) are not flagged.
Draft — for each charge, three ready-to-send letters:
- Cancellation — firm request to cancel and stop all future billing (kills continuous payment authority).
- Renegotiation — a retention/loyalty-discount script to lower a recurring bill before you cancel.
- Data deletion — a GDPR Art. 17 (EU/UK) or CCPA/CPRA §1798.105 (California) erasure request.
Send — every letter ships with where/how to send it. You send it yourself from your own account.

Self-help templates, not legal advice. zombie-killer drafts; the human sends.

Web app

Open the site, paste your statement, hit Find my zombie subscriptions. The scan and the verdicts are free. Unlocking the full letter package is a one-time crypto payment (no account, no card).

Tools:

scan_subscriptions — raw data to recurring charges + zombie verdicts + annualized savings.
generate_letter — draft one cancel / renegotiate / data-deletion letter.
build_letter_package — scan + draft the full package in one call.

Or connect over HTTP at POST /mcp.

Pay-per-call (x402)

The /pro/package route is gated by x402. An agent pays in USDC on Base automatically — no sign-up, no API key.

GET /pro/package?data=2026-05-12,NETFLIX.COM,-12.99&jurisdiction=eu

HTTP API

POST	`/mcp`	MCP-over-HTTP (free).
