RetentionCheck is AI churn analysis built for solo SaaS founders without a retention team.

Cancel feedback piles up in three places: Stripe cancellation events, email replies from churned customers, and CSVs you keep meaning to read. Nobody on the team has time. You are the founder, the customer success lead, the engineer, and Friday afternoon is already gone. Reading 200 raw cancel reasons feels worse than not reading them, so the pile grows and your retention work never starts.

RetentionCheck reads the pile for you. Paste cancellation feedback, upload a CSV, forward exit-survey emails, or connect Stripe directly. Get back four things in under 30 seconds: a Churn Health Score from 0 to 100 with a letter grade from A to F, the top 5 to 8 churn drivers ranked by severity and confidence, direct customer quotes backing every insight (no fabricated quotes, no AI hallucination), and a one-paragraph priority action for the week ahead.

The Churn Health Score is the headline feature. Every analysis starts at 100. Each insight deducts points based on severity: critical drivers cost 20 points, high cost 12, medium cost 6, low cost 2. Grades land at A+ above 90, A above 80, B above 65, C above 50, D above 35, and F below 35. The math is published. Re-run on next month's feedback and the score moves. That is the loop. Fix the priority action, watch the grade improve, prove retention work mattered.

What makes RetentionCheck different from prompting Claude or ChatGPT directly. Two things. First, every driver pulls real customer quotes back into the output, so you are reading what customers said, not arguing with an AI summary. Second, drivers are ranked by confidence based on how many responses cluster around each theme. A complaint mentioned twice in 100 responses will not outrank one mentioned 40 times.

Inputs supported: plain text, CSV with any schema, forwarded emails, Stripe Connect (encrypted token storage, OAuth, automatic weekly refresh), Intercom conversations tagged churn, and Typeform exit-survey responses.

Free tier runs at retentioncheck.com/try with no signup, IP-rate-limited. Authenticated free tier gets three full analyses per month. Founder plan is $99 per month or $950 per year for 100 analyses, weekly Stripe digest, and Connect support. Pro plan is $249 per month or $2,390 per year for unlimited analyses, PDF and shareable links, trend tracking across runs, Investigate (cross-analysis Q and A), and Slack alerts.

RetentionCheck also ships as @retentioncheck/mcp-server on npm. Install once, run churn analysis from inside Claude Code, Claude Desktop, Cursor, or Zed. Five tools, bring your own Anthropic API key.
