Perry is a small platypus button next to the chat box in ChatGPT, Claude, Gemini, Perplexity, Microsoft Copilot, Mistral Le Chat and Grok. Type a rough prompt, click Perry, and he rewrites it in place: a clear goal, the right format and length, and a [blank] for any detail only you know, so the AI never has to guess. Undo brings your words back, and "Show changes" explains what he changed.
The extra: tell Perry once who you are, how much detail you like and your style, and every prompt fits you. Private use leaves the profile out.
Free to start, no account needed. Pro (€5.99 a month, or €4.99 a month billed yearly) is unlimited, uses a more thorough model, and adds prompt history, a saved library and sync. Built in Germany for the GDPR; prompts aren't stored unless you switch history on.
