AI

Knowledge base

Give the assistant your own documents. Text pasted at /ai/documents is chunked and embedded by a background job, then searched by cosine distance, scoped to the caller's own documents.

What you get

• Fixed-size chunking with overlap
• Embeddings with text-embedding-3-small
• pgvector storage in Postgres
• A searchKnowledgeBase tool for the chat

Turn it on

• OPENAI_API_KEY
• Postgres with the vector extension

Where it lives

• lib/rag/index.ts
• lib/rag/chunk.ts
• lib/rag/embeddings.ts
