Frequently Asked Questions

Coplay is an AI-powered coding assistant designed specifically for Unity game development. It lives inside your Unity Editor and helps you write code, debug issues, generate assets, and build features faster using natural language.

Coplay can be installed via the Unity Package Manager. Visit our documentation for step-by-step installation instructions. The process takes about 2 minutes.

Coplay supports Unity 2022 and newer versions. We recommend using the latest LTS version for the best experience.

Coplay is designed for all skill levels. Beginners can use natural language to describe what they want, while experienced developers can use it to accelerate their workflow. That said, understanding basic Unity concepts will help you get more out of the tool.

Coplay can help with virtually any Unity development task: writing scripts, creating editor tools, debugging errors, optimizing performance, setting up scenes, configuring physics, creating UI, and much more. If you can describe it, Coplay can help build it.

Coplay can generate 3D models, sprites/textures and audio files simply by prompting with a description of what you want created.

Yes! Coplay changes to your project are just regular Unity changes to gameobjects, scripts and assets. They work perfectly with Git, Unity Version Control, Perforce, or any version control system you use.

Coplay supports multiple AI providers including OpenAI, Anthropic, Google, and more. You can switch between models based on your preferences and use case.

No, with a subscription you can use Coplay without needing your own API keys. However, you can use Anthropic and OpenRouter API keys with Coplay at no additional cost.

AI costs depend on your usage and which model you choose. Coplay aims to be transparent about the price variations of each model so you can make informed decisions. Check out our How Our Pricing Works guide for more details.

There are several ways to minimize your costs: respond within 5 minutes to benefit from KV caching (up to 10x cheaper), keep your context window light (under 30% usage), start fresh threads for new tasks, and only attach the context you need. Check out our full Cost Saving Tips guide for detailed strategies, or see the Prompt Cost Guide in our docs for model-specific pricing.

Model Context Protocol (MCP) is an open protocol that allows AI models to access and manipulate data from external sources. Read more about it here.

Yes! Coplay supports is both an MCP client and MCP server. As an MCP server, you can connect your own AI tools like Claude Code to use Coplay. As an MCP client, you can configure MCP servers to extend Coplay's capabilities.

MCP for Unity is an open source project that Coplay supports and sponsors. It is a separate product from Coplay entirely. Learn more about their differences here.
