I built a privacy-first couples compatibility quiz with AI coaching

After trying Mojo Upgrade with my partner and finding it outdated and unhelpful, I built kinkSyncAI. Both partners fill out a structured questionnaire independently — neither sees the other’s raw answers. The app scores compatibility and generates personalized AI advice powered by Claude.

Tech stack: Express 5, Vue 3, MongoDB, Anthropic Claude. 880+ tests. Solo dev, launched this week.

One-time €9.99 — no subscriptions, no ads.

Would love feedback from other founders, especially on pricing and positioning.
