AI tools for the parts of a game that eat your weekend: sound, 3D art, animation, code and the trailer. We list the license catch for each one, because the free plan is often the one you can't ship with.
Sound and voice3D models and animationBuild your game with AITrailers and clips
Sound and voice
Silent games feel broken. Get sound effects, music and voice lines in your game before you ship.
3D models and animation
Turn a prompt or a picture into a 3D model, then make it move.
Meshy
Text or image to textured 3D models, with a low-poly mode, auto-rigging and preset animations. Exports to the formats Unity, Unreal and Godot read.
License: Free models need credit to Meshy. Paid plans don't.
Tripo
Text or image to 3D, with retopology and part segmentation, so the mesh you get is one you can edit.
License: Commercial use needs a paid plan. Free models are public.
Cascadeur
Desktop animation software with AI posing and physics. Set a few key poses and it fills in the motion between them.
License: Exporting needs the Indie plan or higher.
Build your game with AI
Describe the game and these tools write the code with you.

Rosebud AI
Make a web game in your browser by chatting. It writes the code, makes the art and hosts the game for you.

Trailers and clips
Players decide in seconds. Cut a trailer from real gameplay, then chop it into clips for socials.

Edit video by editing the transcript. Good for devlogs, narrated trailers and captions.
License: Free exports are 720p with a watermark.
OpusClip
Feed it a devlog or a stream and it cuts captioned vertical clips for Shorts, TikTok and Reels.

Runway
AI video generation and editing, for teasers, animated key art and shots you can't capture in-game.
License: Check your plan's terms before you publish.
Before you ship
Plans and licenses change. Read a tool's terms before you sell anything it made. If AI made art, sound or code in your game, say so where the store asks: Steam asks about AI content players see or hear.
