# Lematter

> Lematter is an open source, self-hostable AI platform for life science research. It delivers grounded, citation-backed answers for biotech, pharma, and healthcare research — the trustworthy alternative to generic AI, with semantic search, a biology knowledge graph, data sovereignty, and compliance controls.

Lematter is built specifically for research and lab use. Every answer is grounded in real sources with verifiable citations, so researchers can trust and check the results. The platform is open source with no vendor lock-in, and can be self-hosted so sensitive data stays within your own infrastructure.

## What is Lematter?

Lematter is an open source life science AI platform — an AI for biotech research that gives grounded, citation-backed answers instead of generic AI responses. It combines semantic search over scientific literature with a knowledge graph for biology research, and is designed for data sovereignty and compliance in regulated research settings.

## Key features

- Knowledge Graph: a knowledge graph for biology research that relates scientific concepts and connects ideas across studies.
- Semantic Search: semantic search for scientific literature that finds relevant research by meaning, not exact wording.
- Citation-backed answers: an AI research tool with citations you can verify, for trustworthy scientific literature review and synthesis.
- Data Sovereignty: a data-sovereign AI platform that keeps data within your own environment; nothing sensitive has to leave your control.
- Open Source: open source AI with no vendor lock-in; everything about how the platform works is open and inspectable.
- Compliance Controls: compliant AI for healthcare research, built to meet standards required in regulated settings.
- Self-hosting: self-hosted AI for research labs, so your infrastructure stays under your control.
- Lab Integration: fits into the tools and workflows bioinformatics teams already use.
