Features

  • Trap-score per subscription rating how predatory the renewal flow is under the new rule
  • One-tap cancel generating a valid cancellation request citing NYC rule and applicable state laws

Field is crowded: Rocket Money (formerly Truebill), Trim, Bobby, Emma, Subbly, Billed, and Revolut already do subscription detection/cancellation; Rocket Money specifically rated 'best-in-class' for subscription detection — pure-play incumbents are well-funded.Best subscription trackers 2026: Rocket Money, Trim, Bobby, Emma, RevolutTrim vs Rocket Money (formerly Truebill): Which Is Better?

NYC rule is finalized and locked to Oct 1, 2026, but federal Click-to-Cancel (FTC) was blocked and never took effect — a precedent that political/regulatory reversal is possible; copycat state bills search returned no concrete results yet, so expansion optionality is unproven.NYC Subscription Cancellation Rights 2026: Click-to-Cancel TruthClick-to-Cancel Rule (NYC DCWP PDF)

Feasibility
6/10

Gmail API + Plaid bank linking + NLP subscription detection is the proven Rocket Money/Trim stack and is buildable as an MVP; the differentiation (regulator-grade cancellation notices citing NYC Admin Code) requires vetted legal templates and jurisdiction-aware logic, adding non-trivial complexity but no hard blockers.Cancellation of Subscriptions - NYC RulesTop 10 Best Subscription Tracking Software | Ranked for 2026
