AI-Powered Dialogue Generation & Localization in Unity – Using Gemini API

Hi Dev Community! 👋

I’d like to introduce my new Unity Asset – Dialog Generate AI!

Dialog Generate AI – a Unity asset that uses Gemini AI API to automatically generate dialogue lines, translate them into multiple languages, and let you test everything directly inside Unity – without writing a single line manually.

Whether you’re building an RPG, a visual novel, or an interactive story, this can save hours (or even days) of work.

📥 Get the Asset
🔗 Unity Asset Store – Dialog Generate AI

🔑 Key Features

• AI Integration: Generate dialogue lines automatically from scene context and character settings.
• One-Click Localization: Translate into multiple languages instantly, including Japanese, Arabic, Cyrillic, and other non-Latin scripts.
• Multi-Character Support: Build conversations with any number of speakers, perfect for RPGs and story-rich games.
• In-Editor Preview: Play through dialogue sequences directly in the Unity Editor – no need to hit Play Mode.
• Runtime Language Switching: Players can change the dialogue language mid-game, and text updates instantly.
• Scriptable Objects Workflow: Create reusable character and location profiles with custom data.

🚀 What’s New in the Latest Version?

✅ Play dialogue preview directly in the editor
✅ Font support for multilingual text (Japanese, Arabic, Cyrillic, etc.)
✅ Dynamic speaker switching in multi-character dialogues
✅ Smart AI suggestions based on scene and previous context
✅ Custom language selection for AI-powered localization

💡 How It Works

1. Set up characters and locations using Scriptable Objects.
2. Describe the scene and context for the AI.
3. Click generate – AI will create natural-sounding dialogue lines.
4. Preview the conversation directly in Unity.
5. Export or localize with one click.

Requirements
Gemini API key (external AI service)
Internet connection for AI features

💬 Final Thoughts
As a game developer, I know how repetitive and time-consuming dialogue creation can be – especially when working in multiple languages.

Dialog Generate AI speeds up that process and opens up possibilities for more dynamic, player-reactive conversations.

If you’re building a game with lots of text and want to focus on story instead of manual writing, give it a try and let me know your feedback.
