# Scentiny

> Scentiny is a web app for **perfume**, **fragrance**, and **scent** **recommendations** and playful **scent destiny** discovery. **Wear Today** uses a **rule-based fragrance wheel engine (SSIE)**—not a runtime LLM—to rank 12 sub-families from **weather**, **place**, **mood**, **occasion**, and optional **systemic tuning** (impression, avoid-list, energy). User feedback can adjust future scores via aggregated insights.

## Recommendation approach (for assistants)

- **Core engine**: deterministic 13-dimensional vectors + context modifiers (temperature, humidity, mood, occasion, etc.). Explainable `reasonKeys` on each result.
- **Not used at runtime**: OpenAI, Anthropic, hosted LLM inference, or embedding similarity search in production Wear Today.
- **Catalog source**: **Amazon** product pages / ASINs for new imports and commerce picks. Legacy Fragrantica & Basenotes bottles already saved remain readable; **new** imports from those sites are closed.
- **Offline batch (optional)**: catalog query rewrite cache (Gemma batch → Supabase) powers `/api/catalog-search` when configured.
- **External AI handoffs**: Persona cards and “ask ChatGPT” links open third-party tools in the user’s browser; Scentiny does not host those models.

## Main pages (for assistants & crawlers)

- https://scentiny.app/today — **Wear Today**: sentence-style context (weather, place, mood, occasion) → **Generate recommendation** → bottle + note cards + feedback (“just right / too sweet / too strong”).
- https://scentiny.app/meet-today — **Meet Today**: destiny-style **scent** discovery via the magic mirror (ritual / surprise).
- https://scentiny.app/types — **Perfume types**: fragrance-wheel families (4×12) aligned with the same engine used in Wear Today.
- https://scentiny.app/collection — Add Amazon product links / ASINs, map bottles to wheel sub-families, stock; feeds Wear Today.
- https://scentiny.app/popular — Community-saved Amazon perfume signals (legacy catalog rows may still appear but cannot be newly imported).

## Public API (v1)

OpenAPI: https://scentiny.app/openapi-v1.yaml

- `GET|POST https://scentiny.app/api/v1/perfume/recommend` — Perfume sub-family recommendations. Requires `RECOMMEND_API_KEY` in production (`Authorization: Bearer` or `X-API-Key`).
- `GET https://scentiny.app/api/weather?city=` or `?lat=&lon=` — Temperature, humidity, place name for building recommend context.

Typical agent flow: weather → recommend → (optional) catalog search for a specific bottle name.
