About Us

GXL is an applied research lab for biomedical AI.

We build what agents need to accelerate the next generation of scientific discovery. Our focus is the foundational work: the knowledge, tools, and systems that let AI operate reliably at the frontier of science and medicine.

Current research and development areas

Scientific Literature

Sy for biomedical papers

Large-scale, multimodal synthesis of biomedical and scientific preprints.

Our AI agent for biomedical pre-prints indexes complete paper contents, including figures, tables, supplementary material, and data files. It processes hundreds of documents in parallel in an efficient and scalable way. Read about it in our blog post about Sy.

Regulatory Literature

Coming soon Sy for FDA documents

This agent ingests clinical reviews, statistical analyses, advisory committee transcripts, approval letters, and Complete Response Letters from the FDA. It compares regulatory decisions across products, extracts FDA reviewer positions, queries structured databases (Drugs@FDA, devices, Purple Book biologics), and analyzes post-marketing requirements.
