Walkthrough

0. Scar tissue — the $430 confession
I pasted receipts into ChatGPT. It invented renewal March 1, real was Feb 15. Missed cancellation. Cost $430. That's why this workflow forces evidence_quote and null if no date. Every advice here carries that cost.
1. Takeout MBOX (3 min)
Takeout → Mail → MBOX — completely free【1995694494649942736†L18-L22】. Parser pattern: gmailTakeoutParser for bulk history【1995694494649942736†L11-L15】.
2. Local-first classification
Use ScanMySubs private model — processing stays in browser【1995694494649942736†L49-L52】. Or Workers AI Llama. Prompt includes "do NOT guess" + evidence_quote.
Prompt: You are SaaS auditor. Extract JSON only: {service, amount, billing_cycle, renewal_date_iso, cancellation_url, evidence_quote}. If renewal not explicit, null. Evidence_quote verbatim 5 words.
3. Draft cancellations with proof
Include evidence_quote → support cancels in 1 reply. Skip and you get 3 back-and-forths = 15 min each.
What Breaks

Workers AI quota resets midnight UTC — burn at 11pm PT and you wait 1hr not 24hr. Takeout spam receipts inflate count 30% — filter from noreply/billing only or you waste neurons. Llama misreads annual as monthly when amount >$100 — cross-check.
