Free planGoogle AI Studio
Google AI Studio is a browser workspace for experimenting with Gemini prompts and building AI prototypes. It exposes model controls and multimodal inputs that are useful when comparing responses or planning an API integration. Free access is rate limited and does not cover every model or capability.
Free planBolt
Bolt builds websites and web apps from natural-language instructions in a browser workspace. You can preview the result, revise the interface and work with project files. Its token allowance makes the free plan useful for testing an idea or making a modest prototype before investing in a larger build.
Free planCursor
Cursor is an AI code editor for working directly with project files, asking questions about a codebase and requesting changes through an agent. Its free Hobby plan suits occasional coding assistance and trying its Composer workflow. This entry requires downloading a desktop editor rather than using a standalone browser chatbot.
