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 that runs in any modern browser, 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 — TypeScript on Three.js for 3D games and Phaser for 2D — which you fully own and can publish, share, and sell. You can read and edit the code in the built-in editor and export standalone builds or the full source project.

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, or start from an image in Explore.
2

Build

The AI agent builds the game — writing code, making the visuals and sound, and testing as it goes. You watch it happen live. Want to review the approach first? Switch to Plan and approve a plan before anything is built.
3

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.
4

Publish

Share a play link, list the game on the marketplace, sell it, or export it.

Key concepts

  • Games — every project is a full game: 2D pixel art, 2D modern, or 3D; top-down, side-on, first-person; desktop or mobile. 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 assets, animations, visual effects, add-ons, a code editor, version history, and game settings. See The Studio.
  • Run modes — Build (the default), Plan (review before building), and Loop (let the AI keep improving your game against a credit budget).
  • Credits — AI work is metered in credits, billed for actual usage after the work happens. Tesana picks the right AI model for every run — there’s nothing to configure. 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.
