Where this is going

From calculator directory to private decision engine

The free core should remain account-free while becoming deeper, more verifiable, and more connected.

Current priorities

  1. Stabilize trust: public tests, correction history, quality schema, better sources.
  2. Rebuild flagship tools with interpretation, scenarios, reverse solving, and decision next-steps.
  3. Build local scenario workspace with export/import and privacy-preserving sharing.
  4. Explore paid cross-device sync, branded exports, team templates, and white-label embeds only after the free answer is complete.
