Three inventories

Big Five, NEO PI-R, and RIASEC — seeded and ready. Add your own with a YAML file.

Model-agnostic

Swap the LLM by changing two env vars. OpenRouter gives you access to 100+ models.

Developer-first

RESTful API with auto-generated OpenAPI docs, typed SDKs, and predictable error shapes.

  -H "Authorization: Bearer sk_live_..." \
  -H "Content-Type: application/json" \
