FAQ

About Prompt Generator

What makes a good AI prompt?

Three things: a clear role for the model, a specific task, and the exact output format you want. The generator wraps your input in that structure automatically.

Will these prompts work with Claude and Gemini?

Yes — the role/task/format pattern is model-agnostic. You may need to tweak system-vs-user wording for chat APIs, but the prompt body itself is portable.

Should prompts be long or short?

Short enough to be specific, long enough to be unambiguous. Most production prompts land between 80 and 250 words. The generator targets that range.
