Apodex is a self-evolving AI research tool designed to tackle complex, high-stakes questions that have no readily available answers. It reasons through problems step by step, verifying every conclusion before advancing to the next, rather than generating a simple chat reply. The output is a verified research brief users can trust, covering domains such as macroeconomics, medicine, ML research, and AI policy. Apodex requires no sign-up for initial use, offering five free research queries to get started.
