How it works
Study once. Remember for good.
Link ChatGPT or Claude
Connect the Cortu connector and just say “save these to Cortu” while you study. Concepts flow straight in — the raw chat never touches our servers.
Daily spaced repetition
A calm, Duolingo-style revision queue in the mobile app resurfaces each concept right before you would forget it.
Printable study packs
Export any subject as a clean US-Letter PDF — a single concept card or a consolidated pack — ready to print and revise offline.
