MindSpace transforms your notes, photos, memories, and knowledge into a living 3D world you can literally walk through.
Today's productivity tools organize our lives into folders, lists, and databases.
But that's not how humans naturally remember things.
We remember:
- 📍 Places
- 🤝 Relationships
- 🚶 Walking through spaces
- 🔗 Connections between ideas
For thousands of years, people have used the Memory Palace (Method of Loci) to dramatically improve recall by placing information inside imagined physical spaces.
Yet modern note-taking and productivity apps still expect us to search through flat folders and endless documents.
MindSpace turns your personal knowledge into a living, interactive 3D environment.
Instead of searching for information, you walk through it.

MindSpace uses AI to generate a personalized world whose layout reflects how you think and remember.
Every room, object, and pathway becomes a meaningful representation of your knowledge and memories.
The idea starts with a question: how can we locate information in our minds, build association, and interact with our own thinking process? Eileen Gu (Gu Ailing) was once asked, "Do you think before you speak? You're so articulate about everything, from geopolitics to aerodynamics to your sport, can you take us to your mind?" That's foundational thinking, and we are building this: something here to take you to your mind.
Sherlock Holmes is also famous for recalling memories through a mind palace, an association method that made him a brilliant investigator and a man of composed mind. Seeing the short gif below, that's how we imagine the 3D space we're creating would be: you're able to pull objects, find slots of memory, and engage with your own thinking process and awareness.
Pics/Screenshots of Demo
Here is a quick look at MindSpace in action. The first picture shows the upload dialogue, where you drop in your photos and notes to start building your world.
The second picture shows the dialogue for adding an object, where a single memory becomes a small item you can place inside a room.
The remaining pictures show real examples of what MindSpace generated, the rooms it built and the memories placed inside them, ready to walk through and explore.
Under the hood, MindSpace isn't a chatbot, it's a small pipeline. When you upload photos or notes, an LLM agent reads through everything and decides how it should be organized: does this belong in a room that already exists, or is it something new? The same way you'd naturally group a trip, a person, or an event in your head, rather than a folder of files. For every new room, the agent writes a short text description of the space, and World Labs' Marble model turns that description into a real, walkable 3D environment, a Gaussian splat, which is essentially a cloud of millions of colored points instead of a traditional 3D mesh, so it can look photorealistic without anyone modeling it by hand. Your actual memories then become small 3D objects placed inside that room at eye level, so you can walk up to one and click it to read what it means. Everything renders in the browser over WebXR, so the same world works on a laptop with a mouse or in a VR headset, no extra software needed.
