Tesana

Tesana is an AI game engine that lets you build entire games by chatting with the AI. You describe the game you want — a first-person adventure on a desert island, a survival game with crafting, an old-school action RPG — and Tesana generates a playable 3D world with mechanics, characters, and UI built in. No engine setup, no coding, no asset hunting. Just type a prompt and start playing.

The core of Tesana is the Muranyi model series, a set of code-based game models that take text input and produce complete game logic and 3D environments. The latest version, Muranyi-3, is described as the world's most powerful AI model for making games. It handles everything from world generation and physics to NPC behavior, quests, and visual style. You can upload reference images to guide the look, and you can remix existing games made by other users — tweaking mechanics, difficulty, or visuals without starting from scratch.

Tesana is aimed at anyone who wants to make games but doesn't want to learn programming or spend months in a game engine. Game developers can prototype ideas in minutes, indie creators can build polished experiences, and hobbyists can explore what AI-assisted game design feels like. The platform also features a community gallery where you can discover and play games made by others — then remix them into something new.
