Tool
Leonardo.AiCommercial use allowed

Best for
General concept art and icon ideas
Unity users who want AI inside the editor
What it does
General image and video generation platform with trainable custom models; usable for concept art, item icons and texture ideas.
Unity's AI tools (Unity is retiring the "Unity AI" name): an in-editor assistant for project questions, code and Editor actions, plus generators for images, textures, sounds, 3D models and animations, metered in Unity Credits. The Unity CLI, MCP server and Unity's official agent plugin are free.
Verdict
For general concept art and icon ideas; free-tier output can be used commercially but is public and Leonardo holds rights to it, while paid plans give you ownership.
For Unity 6 users who want AI inside the editor: credits are included on Pro, Enterprise and Industry, while Personal gets a 14-day trial and then a paid subscription. Unity says you own the outputs, but third-party generator terms also apply.

Using the generators is also governed by third-party terms (Layer, Scenario, Uthana). Generated assets carry "UnityAI" metadata. Commercial-use terms for outputs aren't stated separately. source
