What is Tesana?

Tesana is an AI game-building platform. You describe the game you want in plain language, and Tesana’s AI agent builds it — a real, playable game running on the open-source Godot engine, with genuine source code behind it. That last part matters: Tesana doesn’t generate a video that looks like a game or lock you into a proprietary runtime. It writes real code in a real game engine, which you fully own and can monetize, publish and share. You can read and edit the code in the built-in editor, export standalone builds, and open the full project in the Tesana Desktop App.

The core loop

1

Describe

Type your game idea into the prompt box — genre, art style, mechanics, setting, win/lose conditions. Attach reference images if you have a look in mind.
2

Plan

The AI proposes a build plan you can review, adjust, and approve — so you know what you’re getting before the heavy work starts.
3

Build

Approve the plan and the AI agent builds the game — writing code, generating assets, and testing as it goes. You watch it happen live.
4

Play & iterate

Play the result right in the browser, then keep prompting: add features, fix bugs, change the art, tune the difficulty. Every game is built through iteration.

Key concepts

  • Games — every project is a full game: 2D pixel art, 3d games, top-down, first-person; desktop or mobile-oriented. Play in the browser, publish to the marketplace, or export.
  • The Studio — your workspace: chat with the AI on the left, live game preview on the right, plus an asset library, a code editor, add-ons, version history, and game settings.
  • Models — pick the AI that builds for you: Muranyi 3.5 (balanced default), Atomos (most capable model with significantly better results), or Muranyi Fast (cheap, quick edits on existing games). See Models.
  • Credits — AI work is metered in credits, billed for actual usage after the work happens. See How credits work.

​
Who owns what you make?

On any paid plan, you do — gameplay, logic, generated source, and full commercial rights, and those rights survive cancellation. Details in Ownership & IP.
