The best AI tool for your first game depends on where you want the game to end up. Pick your goal below. If you're unsure, take the 5-question matcher.
Goal 1: a link your friends can play tonight
Rosebud AI
Describe a game and play it in the browser. The free plan starts with 8,000 credits. Paid plans: Indie Dev $15/mo, 10x Dev $30/mo (adds commercial rights), Pro $50/mo (adds code download and Windows export). Try Rosebud
Goal 2: a real game on Steam or app stores
GDevelop (no-code engine with an AI agent)
The engine is free and open source (MIT). The free plan includes 40 AI credits a month. Silver is $7.99/mo, Gold $13.99/mo (adds iOS publishing), Pro $39.99/mo. Try GDevelop
Godot + an AI coding tool
Godot is free. Pair it with an AI coding editor like Cursor (free plan, then from $8/mo). You'll learn real code, and you own everything. See our Godot/Unity + AI setup guide.
Goal 3: a Roblox experience
Roblox Assistant
Built into Roblox Studio. It can write scripts, insert Creator Store assets and generate meshes. Roblox's docs don't list a separate price.
You'll also need art and sound
See AI game asset generators and the $0 stack. Before you sell anything, read who owns your AI-made game.
Questions people ask
What is the easiest AI tool to make a game for a total beginner?
If you want a playable browser game with no code and nothing to install, a prompt-to-game builder such as Rosebud AI is the gentlest start. Its free plan begins with 8,000 credits, and Rosebud says they refill weekly in eligible regions.
Can I put an AI-made game on Steam?
Yes, if your tool lets you export it and grants commercial rights. Rosebud includes code download and Windows export from its Pro plan ($50/mo). GDevelop and Godot give you the project files.
Do I need to know how to code?
No. Rosebud, GDevelop's AI agent and Roblox Assistant all work from plain-language prompts. Knowing a little code helps once you move to Godot or Unity.
