How our AI builds games

Tesana doesn't generate a picture of a game — it builds a real, playable one. Our research spans the model that writes the game and the way it works: every build runs on our most capable model, and Loop keeps building long after you've walked away.

Every build runs on our most capable model

Describe a game and Tesana builds a real, playable one — smarter, more creative, and with fewer bugs than ever before. There's no model to pick: Tesana chooses the right one for every run. The video above is what a single prompt looks like today.

You don't need any technical setup or engine knowledge. You describe what you want to play; Tesana writes the game behind it.

Smarter, and more creative

Smarter, and more creative

Tesana builds cleaner, more coherent games that are easier to extend over time — and it comes up with mechanics, twists, and ideas you'd never have thought to ask for. The result is games that work the first time more often, and worlds that hold together as they grow.

Better games, across the board

Tesana produces more polished games at every stage of creation: • Smarter — deeper game logic, better characters, bigger worlds that hold together • More creative — fresh mechanics and ideas, not just what you asked for • Fewer bugs — more of your games just work on the first try • One prompt, not ten — big builds that used to take many rounds often land in one Each of these compounds, so the same prompt produces a noticeably better game than it did before.

Loop: a game that builds itself

Loop: a game that builds itself

Loop is our long-horizon build mode. Where a normal build happens once and hands over, Loop keeps going. It splits your game into areas and builds them in parallel, opens the game and looks at what's on screen, finds what's weak, and builds it again — better each time. It runs for hours, unattended, until the work holds up.

Judged by a separate critic

The part that changes everything: when an area is finished, a second AI — one that had no part in building it — reviews it against a real, shipped game in the same genre and scores it. Anything that falls short goes straight back to be rebuilt. That cycle of build, play, judge, and rebuild is what makes a game from Loop feel designed rather than generated.
