Google AI Studio
Google's free playground for prototyping with the Gemini API before writing real app code.
What is Google AI Studio?
Google AI Studio is a free, browser-based IDE for experimenting with Gemini models — a prompt playground, structured output and function-calling setup, and a "get code" button that exports a working starting point in your language of choice. It's aimed at developers prototyping before they commit to a real integration.
Unlike a general chat interface, AI Studio exposes the actual API parameters developers need: system instructions, temperature, safety settings, JSON schema for structured output, and tool/function-calling configuration, all with live previews. The tool itself is free; you only pay once you move to production Gemini API usage, billed separately through Google Cloud.
Key features
- Prompt playground for every current Gemini model
- Structured output (JSON schema) testing
- Function-calling and tool-use configuration
- One-click "get code" export to Python, Node, or curl
- Multimodal testing — images, audio, video, and PDF input
- Free API key generation for developers
Pros
- Genuinely free to prototype in, no credit card required to start
- Exposes real API parameters instead of hiding them behind a chatbot
- Fastest path from idea to working Gemini API code
Cons
- Interface is utilitarian and clearly built for developers, not casual users
- Production API usage still costs money once you scale past the free quota
- Less useful if you're not planning to build something with the API
