What is usePrompt?

usePrompt is a focused tool for testing and perfecting single "one-shot" generative AI prompts. It's designed for developers, designers, and prompt engineers who need to iterate quickly without the overhead of a conversational interface.

It's a Lab, Not a Chatbot

The primary purpose of this tool is to perfect a single set of inputs (system instruction + user prompt) to get a desired output. It is not designed for multi-turn, back-and-forth conversations. Think of it as a laboratory for your prompts, where you control the variables and examine the result.

Every time you click "Run Prompt," the model processes only the current input, without remembering previous interactions. This ensures you are testing the prompt in isolation, which is crucial for reliable and reproducible results.

Your Privacy is Our Priority

We believe in complete data privacy. usePrompt acts simply as a bridge between your browser and the generative AI provider. We don't have a backend server, which means:

• We never save, track, or see your API keys. Your key is only used in your browser for the API request.
• We never save, track, or analyze your prompt history. Your history is stored exclusively on your machine in your browser's local storage.

You are in complete control of your data, always.

Key Features:

• One-Shot Testing: Focus on perfecting a single prompt and its output.
• Multi-Modal Support: Test prompts that generate text, code, or images.
• Shareable Prompts: Compress your entire setup into a single shareable URL.
• Private History: Your past experiments are saved only in your browser. We never see it.
• Ephemeral API Keys: Your key is never saved on any server. It's gone when you close the tab.
• Responsive Design: Works seamlessly on both desktop and mobile devices.
