How PromptAI works
PromptAI takes the rough text you type and rewrites it into a structured, high-quality prompt in seconds. Under the hood it applies techniques like role assignment, chain-of-thought scaffolding, and constraint framing — the same methods prompt engineers use manually — so you get dramatically better responses from ChatGPT, Claude, Gemini, Cursor, and Claude Code without spending 20 minutes crafting the perfect prompt yourself.
Paste anything into the demo: a vague task, a half-formed question, a one-liner idea. PromptAI structures it with a clear role, relevant context, a precise task definition, and explicit constraints, then hands the finished prompt back to you ready to paste into any AI tool. If you love the results, a paid plan gives you unlimited enhancements plus the Chrome extension that works directly inside ChatGPT, Claude, Gemini, and more.

Real model quality. The same GPT-4.1-mini backbone used by paying subscribers powers every demo enhancement — no watered-down version.
Frequently asked questions
The PromptAI 360 demo is a free prompt enhancer you can use in the browser without an account. You type rough text, and PromptAI 360 rewrites it into a structured prompt with a role, context, task, output format, and constraints. It is the same enhancement engine paying subscribers use, not a reduced version.
No. Your first three enhancements on the PromptAI 360 demo require no account, no credit card, and no browser extension. After that, a free 5-day trial gives you ten enhancements per day, and paid plans start at $7.99 per month.
Prompts enhanced by PromptAI 360 work in any tool that accepts text: ChatGPT, Claude, Gemini, Copilot, and Perplexity. The PromptAI 360 Chrome extension adds a button directly inside browser-based AI chats, and the macOS desktop app enhances text anywhere with the ⌘⇧P hotkey, including Claude Code, Cursor, Antigravity, VS Code, and Warp.
Under three seconds. PromptAI 360 runs on a GPT-4.1-mini backbone, so rewriting a prompt is faster than refining it by hand.
No. PromptAI 360 processes your text and returns the enhanced prompt without keeping it, and prompts are never used for model training.
A template library gives you a fixed list of prompts to copy and adapt. PromptAI 360 rewrites whatever you actually typed, so the structure fits your specific task instead of forcing your task into someone else's template.
Take it with you: the AI prompt enhancer works in every AI tool, the ChatGPT prompt enhancer works inside ChatGPT, and the prompt enhancer for Claude Code lives in your terminal.
