BUILD WORLDS.
LEARN ANYTHING

Type any topic and a 3D world rises around it — every building a memory locus, every lesson anchored to a place. Powered by Claude.

▼ YOUR WORLDS

FEATURED WORLDS

Step into a hand-crafted world instantly — no waiting. Each one shows a different theme Claude can build for any topic you type above.

YOUR WORLDS

Every world you build is saved. Step back in any time — your memory icons, chats, and repositories are kept.

Your Avatar

Make the hero yours. Lessons you conquer mint equippable gear themed to what you learned.

SAVE & BACKUP

Your worlds, notes, files, and flashcards live in this browser. Save Lessons to Computer writes LociWorld.zip — an Open Knowledge Format bundle (LociWorld / Worlds / <world> / <building>) of .md files with YAML frontmatter, both human-studyable and ready for any AI agent. Each save overwrites the same file (on Chrome/Edge it remembers where you put it). The backup file is a single .json just for restoring later or on another device.
