Google AI Studio

Google AI Studio is Google's free, browser-based workspace for building with the Gemini models. Where the Gemini app is a finished assistant for everyday use, AI Studio is the maker's side: a place to write and refine prompts, adjust model settings, and see exactly how the models respond before wiring them into your own software. It runs at aistudio.google.com, signed in with a Google account.

In it you can experiment with different Gemini models, tune parameters such as temperature, work with text, images, and long documents, and design system instructions. When a prompt behaves the way you want, AI Studio hands you the corresponding code and an API key so you can move the same behaviour into an application.

It fits developers, technical makers, and curious tinkerers who want to prototype AI features and understand the models directly — not people looking for a ready-made chatbot, who are better served by the Gemini app.

To begin, open aistudio.google.com, sign in with a Google account, and start a prompt; the studio itself is free to use, with no credit card to experiment.

The honest limits, stated clearly. AI Studio the workspace is free, and it offers a free tier of the Gemini API for development, but that free API tier has rate and usage limits and its data-handling terms differ from paid usage — for production or higher volume you move to the paid, billed Gemini API in Google Cloud. It is a developer tool, so it assumes some comfort with prompts and code, and models, limits, and terms change often. Read the current terms before sending sensitive data through the free tier.
