Prompt Template Builder for ChatGPT, Claude and Gemini

About the Prompt Template Builder

A good prompt says what you want, who it is for and what the answer should contain. This builder does that structuring for you. Pick a template, fill in the fields, press Build Prompt, and copy the finished text into ChatGPT, Claude, Gemini or any other chat assistant. Nothing is sent to a chatbot from this page and no text is generated by a model here; the prompt is assembled from the template wording and your answers.

There are 23 templates in eight groups: Writing (blog post, email draft, product description, social media post), Coding (code review, function, debugging, API design), Business (SWOT analysis, business plan outline, meeting agenda), Marketing (ad copy, SEO content brief, landing page copy), Education (lesson plan, explain a concept, quiz), Creative (story starter, character profile), Analysis (data interpretation, pros and cons) and Image (a Midjourney-style prompt with an --ar aspect ratio, and an illustration description).

For example, the Email Draft template asks for a subject, recipient, purpose and tone. Fill in "rescheduling Friday's demo", "a client", "propose Tuesday instead" and "polite", and you get a complete instruction that also asks for a subject line, greeting, key points and sign-off. Any field you leave empty stays in the prompt as a bracketed placeholder such as [tone], so you can fill it in later.

If no template fits, switch to Custom Prompt, describe the task and add context; the builder wraps it in a short structured request. Before pasting long input into a prompt, the Word Counter shows how long it is, and the Code Beautifier tidies code you want reviewed.
