Full description

Know what you’re picking up—and what to do next. Isaac Codex brings your Isaac encyclopedia, item recognition, and AI run help together in one place. LOOK IT UP, EVEN OFFLINE Browse items, trinkets, characters, enemies, and route references. Find effects, unlock requirements, and interactions while you play. Download the catalog to browse without a connection. IDENTIFY AN ITEM Point your camera at the game or choose a screenshot. Recognition runs on your device and takes you straight to the matching entry, so you can see what an item does before you take it. ASK ABOUT YOUR RUN Not sure whether two items work together or which route to take? Ask in your own words. You can type, speak, or attach an image, then follow relevant entries to check the details. The encyclopedia and item recognition are free. Your first AI answer is free. Continued AI use requires a subscription and available credits. Monthly and annual plans each include 2,000 AI credits per month during the subscription; unused monthly credits do not roll over. Additional credits can be purchased separately. Credit use varies with the work performed. Subscriptions renew automatically unless canceled through your store account; current prices and terms appear in the app before purchase. AI answers can be wrong. Check the relevant entry and game version.
