Knowledge Base AI

Turn your documents into a searchable AI knowledge base.

Upload PDFs and text files. Lexora chunks, embeds, and serves them as a RAG-backed AI assistant — free to create, cited answers, OpenAI-compatible.

Free knowledge base creation

Create knowledge bases and upload documents without paying a cent. You only pay when the AI answers a question.

Citations, every answer

Every response comes with source citations: file name and page number. Enterprise users expect this — Lexora ships it by default.

Distributed embedding + storage

BGE-M3 embeddings run on Lexora's distributed network. Vectors are stored under your account in pgvector. No infra to manage.

Scale with your data

Free 1 KB / 15 MB. Pro: 10 KBs / 50 MB. Enterprise: dedicated nodes, custom storage limits — your data, your isolation.
