Features

Builds prompts with role, context, format and rules. Works for ChatGPT, Claude and Gemini. Gives a completeness score.

Use Cases

Draft a clear prompt before you paste it into a chatbot. Reuse one structure across AI models. Spot missing details in a weak prompt.

Comments

Structuring prompts around role, context, format and rules is a practical approach, and the completeness score is a helpful check before pasting into a model. One idea that could strengthen it further is showing a before-and-after example for the same task, so users can see how adding context or constraints changes the output. Do the generated prompts stay portable across ChatGPT, Claude and Gemini, or do some fields need adjusting for each model?

Nice idea to score how complete a prompt is. Most people don't know what they're missing until the answer comes back weak. Could it suggest the missing piece too? E.g. "add who the audience is" when the context is empty. I'd also love saved templates for prompts I reuse every week.

What makes this AI prompt generator different from ChatGPT? Most people already use ChatGPT to create prompts, so it would be helpful to highlight the unique features and benefits of this tool. Adding ready-made templates, better prompt optimization, and examples could make it more useful.
