Enterprise Edition

The knowledge base requires Aicser Enterprise Edition.

Knowledge Base

The knowledge base lets you upload documents that the AI references when answering questions. Use it to provide business context — metric definitions, data dictionaries, terminology — that helps the AI generate more accurate queries.

Supported formats​

  • PDF
  • DOCX (Microsoft Word)

How it works​

When you upload a document:

  1. Aicser extracts the text
  2. The text is split into chunks and converted to vector embeddings
  3. Embeddings are stored in PostgreSQL using pgvector (or JSONB cosine similarity as a fallback)

When you ask a question, Aicser retrieves the most relevant chunks and includes them as context in the AI prompt. This is Retrieval-Augmented Generation (RAG).

Uploading documents​

  1. Go to Knowledge Base in the sidebar
