# ChatoAI backend

Search + RAG proxy for the oAI / ChatoAI mobile app (DuckDuckGo web search +
PDF/DOCX text extraction + MiniLM embeddings). The on-device model still writes
every answer; this service only supplies grounding context.

Endpoints: `GET /health`, `POST /search`, `POST /ingest`, `POST /retrieve`.

> When hosting on a Hugging Face **Docker Space**, this file must be named
> `README.md` at the root of the Space repo, next to the `Dockerfile`,
> `server.js`, `package.json`, and the `src/` folder. `app_port: 8787` tells
> the Space to route traffic to the port the server listens on.
