AI Prompt Copilotとは
One-click prompt improvement for ChatGPT, Claude, Gemini & Grok. Deep optimization, 9 modes, prompt history. Better answers from AI start with better prompts — but writing a good prompt every time is tedious. AI Prompt Copilot does it for you.
Type your rough request, click the sparkle button, and your prompt is instantly rewritten into a clear, expert-level instruction — right inside ChatGPT, Claude, Gemini, and Grok. No new tabs, no copy-paste, and no API key required.
WHAT IT DOES
Turn "write a cover letter" into a complete, role-assigned, structured prompt that actually gets you a usable draft. Turn "explain this" into a prompt that gets a clear, level-appropriate answer. It applies real prompt-engineering techniques (expert roles, structure, constraints, and self-refinement) automatically — so you don't have to learn any of it.
WHY PEOPLE USE IT
- Save time — stop rewriting and re-asking. Get a great answer on the first try.
- No technical setup — unlike other tools, you don't need an OpenAI/API key on Pro. It just works.
- Works where you already are — ChatGPT, Claude, Gemini, and Grok, with one click.
- Better results on real work — emails, resumes, marketing copy, studying, coding, research, and more.
