Make games with AI.
Make and play games with friends and AI. Generate models, textures, images and audio, shape your game in the engine, and publish it for others to play. Free, in your browser.
How it works
Describe your idea, shape it with AI, and test it with friends.
1. Describe
Tell Gessa the game in plain language, or start from an example prompt.
2. Build
Create the scene, models, textures, images, audio and game rules with AI. Keep refining the project through prompts or direct edits in the engine.
3. Play
Test your game in the browser with a friend, then publish and share its game link. Keep building together as you improve the experience.
Create worlds, maps and everything in them
Build the place, the things players interact with, and the rules that bring it to life—all with Gessa’s AI.
Make a world or game map
Describe an island, a race course or a place to explore with friends. Work with the AI on the layout, scenery and interactions, then playtest and keep shaping your world.
Start building your worldGenerate models and textures
Create a prop, collectible or piece of scenery for your game. Generate textures for its surfaces and inspect the result in your scene. Use Blender workflows for detailed modeling.
Make 3D game assetsGive your game its own sound
Generate audio for the world you are building: a collection sound, an ambient background or music. Test how it sounds during play and refine it alongside your game.
Create models, textures and audioMake multiplayer games with AI and friends
Build together in the same project, then play together in the game you made.
Use live collaboration to shape the game with a friend or your team. Ask the AI for the shared activity you want—collecting, racing or exploring—and test what each player sees. Gessa includes the multiplayer engine, so you can focus on the game’s rules and the experience you want to share.
A real engine
Gessa is built on Three.js, the open-source 3D library of the web, rendering through its WebGPU renderer with WebGL2 fallback. Server-authoritative multiplayer and live collaboration are built in, and a library of 437 generated models is there to browse.
