Best for
NPC voice lines and SFX on a paid plan
Unity users who want AI inside the editor
What it does
Text-to-speech, voices, sound effects and music generation; usable for NPC voice lines and SFX.
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 NPC voice lines and SFX; free-plan output is non-commercial, so a paid plan is required to ship.
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.

Unity's AI Guiding Principles say you own your input and output data, regardless of the partner model used, and that you're responsible for making sure generated assets don't infringe third-party rights. 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
