Open-source workplace AI platform that connects company knowledge across business systems and answers questions with citations, respecting each person's permissions.
PipesHub connects AI applications to the knowledge already scattered across a company's business systems, so an answer no longer depends on which tool somebody happened to search first. It links Slack, Google Drive, GitHub, Microsoft 365, Notion and more than fifty other systems into one context layer.
Retrieval runs over a knowledge graph that captures relationships between records, with block level citations pointing back at the original document. Any LLM provider can sit behind it, deployed inside your own VPC so data never leaves your infrastructure.
Several jobs sit on top of that shared context layer.
- Permission-aware search: source level access controls are enforced, so people only see records they are already authorized to read.
- Enterprise connectors: more than fifty connectors arrive with real time and scheduled indexing.
- No-code agents: agents are built visually and can execute actions across connected tools.
- Artifacts and code execution: reports, charts and dashboards are generated inside a sandbox.
- Multimodal input: images, diagrams and scanned files are understood, alongside voice interaction.
The backend is Python with FastAPI, storing documents in MongoDB, vectors in Qdrant, OpenSearch or Redis, and the graph in Neo4j or ArangoDB. Deployment is Docker Compose, driven by an interactive installer that checks prerequisites, generates secrets and writes an environment file for you. A managed cloud edition is announced but not yet available, so self-hosting is the only way to run it today.
