A simulation engine for the worlds in your head. Describe an environment in natural language and explore it in your browser — with materials, physics, and behaviour grounded in how things actually work.
Realis generates spatially consistent, physically grounded environments you can step into, change, manipulate, interact with and share across the settings that matter for the work you do.
Describe a place in plain language. Future inputs will include reference images, sketches, and videos or anything that conveys the content, layout, and style of a scene.
Every object has mass, material, and behaviour. Gravity, fluids, heat, and reactions follow real rules, different in every setting.
Walk through your world. Pick things up, pour, mix, drop, heat, combine. No installation, no account, nothing to learn first.
Make changes that stick. Save worlds, branch them, share a link. Pick up where someone else left off.
Kitchens, classrooms, forests, deep ocean, orbital stations, volcanic terrain. Each setting brings its own rules of what is possible.
Use the world as an interactive demo, an embedded widget, training data for an agent, or a starting point for a real production.
Move from an idea to a naturally adherent, interactive and walkable environment.
Write a prompt, pick a setting, or refine an example. The system understands the context and handles the rest: proposing a structured scene and simulating physics and adheres to real-world rules.
Behind the scenes, the system first plans what the scene should look like, then checks that everything makes sense, and finally applies real-world physics so everything behaves correctly.
Walk, look around, manipulate. Every interaction resolves through a real model of how materials and forces behave in real life. Save what works, share a link, iterate.
One engine, distinct workflows. Whether you're prototyping a film scene, training an autonomous system, teaching a class, or shipping an interactive experience — the foundation is the same.
Concept, narrative, and visual development. From a line of dialogue to a fully walkable set, before anything is built or filmed.
Interactive, embeddable experiences for games, XR, and immersive media. A real-time environment your players or readers can step inside.
Train and validate against environments that follow real-world rules. Robotics, design review, safety drills, scientific exploration.
Hands-on practice for the things books and videos can only describe. Labs without lab access, field sites without travel, scenarios too rare to recreate.
Three real generations from short prompts. Click through to see the world the engine produces. Every object is ready to interact from the moment the world loads.
