Frequently asked questions

Why does a structured prompt give better answers?

AI models answer best when they know who they should act as, exactly what to do, for whom and in what shape. Spelling out the role, task, context, audience, tone, format and constraints removes guesswork, so you get a usable answer on the first try.

Which AI tools does it work with?

Any of them: ChatGPT, Claude, Gemini, Copilot, Mistral, Llama and others. The result is plain text you paste into the chat box.

Should I add examples?

When you need a specific style or structure, yes. One short example of a good answer is often the fastest way to get the format you want. Leave the field empty when it doesn't matter.

Is what I type stored or sent anywhere?

No. The prompt is built in your browser and nothing is sent to a server or to any AI. It's only shared when you paste it somewhere yourself.

Are my files uploaded anywhere?

No. Prompt Builder runs entirely in your browser. Your files are processed on your device and are never sent to a server.

Is there a file size limit?

No fixed limit. The only limit is your device's memory. Very large files work best in a desktop browser.
