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.
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.
FOR TEACHERS & CREATORS
Build a world from your own curriculum: upload readings and slides, paste your learning standards or certification outcomes, and Claude raises a world whose buildings teach them in order — then hand-edit every lesson before sharing it. Learners load a world file and play.
YOUR SECOND BRAIN
Turn your own notes into a city you can walk. Import markdown or text notes — each becomes a building, its key lines become memory anchors on pedestals inside, and your Archivist guide + Adam quiz you on what you already captured, so it stays remembered instead of archived. Works offline; your notes stay in this browser.
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.
Time’s up!
Building Repository
Your study materials live here, like a project folder — notes, PDFs, PowerPoint/Word/Excel, code, and images. Your guide reads their content (and sees your images) while teaching.
Also mirrored to Documents/LociWorld/<World>/<Building>/ with a README and lesson notes.
Stored in this browser, and your guide reads these notes/PDFs while teaching. Save Lessons to Computer writes LociWorld.zip — an Open Knowledge Format bundle of .md files (lessons, your files, flashcards, teacher chat) any AI can read; each save overwrites the same file.

🧠 Second Brain City
Import your own notes. Each note becomes a building, its key lines become memory anchors, and the city becomes a map of what you know.
1 · Your notes
Markdown (.md) and text (.txt). A folder's subfolders become city districts. Up to 24 notes per city.
2 · Raise the city
Walk your knowledge like a memory palace: every building is one of your notes, every pedestal inside holds one of its key points. Your Archivist coaches recall from your own words, and Adam tests whether you still know what you wrote. Spaced repetition keeps the city bright.
🏗 Creator Studio
Design a standards-aligned world: add your source material, state the standards, generate, then edit every lesson by hand.
1 · The curriculum
2 · The world
The world file is what you share — learners load it from the home screen with “⬆ Load a world file.”
