Knowledge Stack gives you a complete backend for knowledge management. You ingest documents, Knowledge Stack processes and chunks them, and you query that knowledge with semantic search or AI-powered conversations — all through a clean REST API.

​
What you can do

Ingest documents

Upload files or raw content via POST /v1/documents/ingest. Knowledge Stack processes, chunks, and indexes them automatically. Ingesting a new version of an existing document is equally straightforward.

Semantic search

Run natural-language queries against your knowledge base with POST /v1/chunks/search. Results are ranked by semantic relevance, not just keyword overlap.

AI threads

Create a thread and send user messages. Knowledge Stack retrieves relevant context from your documents and streams an AI-generated response — no RAG plumbing required on your end.

Multi-tenant workspaces

Every resource belongs to a tenant. You can create and manage multiple tenants, keeping each customer’s knowledge completely isolated.

Permissions & groups

Control who can read or write specific parts of your knowledge base using path-level permissions. Group users together and assign permissions to the group.

Custom workflows

Define ingestion workflows and invoke them on demand. Monitor runs, inspect status, and rerun failed jobs through the Workflows API.

​
Base URL

All API requests go to: 
https://api-staging.knowledgestack.ai
All endpoints are versioned under /v1. A full request path looks like:

​
API version

The current API version is v1. The version is part of every endpoint path, not a header.
