SubStack Auditor
An automated SaaS that scans a company's subscription stack, identifies unused or duplicate tools, and negotiates cancellations or downgrades via AI.
The problem
Founders on Reddit and Indie Hackers repeatedly complain about 'subscription creep'—paying for overlapping tools like multiple AI writers, analytics dashboards, and design apps they barely use, wasting 15–30% of their monthly budget[1].
Proposed solution
A lightweight dashboard that ingests billing emails or CSV exports, maps subscriptions to usage patterns, flags redundancies, and auto-generates cancellation emails or negotiation scripts using AI.
Target audience
Bootstrapped SaaS founders and small agency owners managing 10+ subscriptions
Key features
- CSV/email ingestion for subscription data
- AI-powered redundancy detection
- Auto-generated cancellation/negotiation emails
- Monthly usage vs. cost dashboard
- One-click cancellation links
Monetization strategy
$9/month for individuals; $49/month for teams with multi-user access and audit reports
Skills to build it
- Email parsing (Python/Node)
- AI text generation (OpenAI/Claude)
- Basic SaaS UI (React + Tailwind)
- CSV processing
- Stripe integration
