We teach models to reason about biology. CellType CLI puts that in your terminal. celltype-cli orchestrates 100+ research tools into a single CLI. A general-purpose agent doesn't know how to interpret a bioactivity profile or assess target safety liabilities. celltype-cli does. How it works: 1. Plans the research strategy for your question 2. Runs 100+ biology tools (deterministic) 3. Synthesizes a grounded report — every claim cites a tool output Built by CellType (YC W26)
