Open Prompt Perfector →The Prompt Perfector is a local tool that transforms vague instructions into high-performance structured prompts. It supports four formats: Claude (XML tags), ChatGPT (Markdown), Gemini (persona-first) and a universal framework compatible with any model.
È il fourth project published in AI-LAB: the entire interface — input panel, generation engine and output panel — was generated by conversing with an AI model, without manually writing or editing any code.
How it was built
The project was built with Google Gemini for ideation and Anthropic Claude, starting from a natural-language description of the desired result. The tech stack — HTML, Tailwind CSS and JavaScript for prompt generation logic — was chosen and implemented entirely by the AI in a single standalone file.
What the tool shows
- Four prompt formats: Claude (XML), ChatGPT (Markdown), Gemini (persona-first) and Universal (RTCE framework).
- Tone and style selection: professional, friendly, creative or technical — applied to the generated prompt structure.
- Two detail levels: Standard for concise prompts, Deep for prompts with examples and edge cases.
- Copy, download and reset: the generated prompt can be copied to clipboard or downloaded as a .txt file.
Privacy note
The tool runs entirely in the browser: no data is ever sent over the internet. Prompt generation is performed locally via JavaScript.
