AI DevKit – Free AI Tools for Unity

AI DevKit - AI Tools for Unity

Getting AI into your Unity project takes longer than it should.

AI DevKit gives you a fluent runtime API and a full set of Editor tools — so you can call AI from your game code and generate assets without leaving Unity.

No server. No backend. Just paste your API key and start generating.

What Is AI DevKit?

AI DevKit is a Unity package for integrating AI into your game. This is the free version, with two layers: Runtime API and Editor Playgrounds

Runtime API

A fluent C# API for calling AI from your game code at runtime.

Use extension methods like directly on strings, Texture2Ds, or AudioClips — no boilerplate, no manual HTTP setup.

Call AI generation from anywhere in your game code with a simple fluent pattern:

Text & Chat

• "Hello".GENCompletion() — Chat/text generation
• "Write a quest".GENResponse() — Responses API (most capable)
• "Parse this".GENStruct<T>() — Structured JSON output mapped to a C# type
• "C# quicksort".GENCode() — Code generation

Image

• "Neon fox".GENImage() — Text-to-image
• texture.GENInpaint("add glow") — Image editing / inpainting

Audio

• "Hello world".GENSpeech() — Text-to-speech
• audioClip.GENTranscription() — Speech-to-text
• audioClip.GENTranslation() — Speech-to-English translation
