Keen — every prompt, sharper.

Turns vague prompts into expert-level instructions before you hit send — on Claude, ChatGPT, Gemini, and Perplexity.

Keen turns a rough idea into the prompt an expert would have written — right before you hit send. Most people don't get mediocre AI responses because the AI is limited. They get mediocre responses because of how the request was worded. Keen closes that gap automatically: click Enhance on Claude, ChatGPT, Gemini, or Perplexity, and your prompt is rewritten with the structure, context, and constraints an expert in that specific task would have included — before you ever send it. What makes Keen different from a generic "make this better" rewriter: • Calibrated, not maximal. A quick question gets a light touch. A resume rewrite or a technical spec gets real structure. Keen reads how much your prompt actually needs instead of padding every request with the same rigid template regardless of what you asked for. • Never invents your details. If something's missing — a budget, a timeline, a name — Keen flags it as an editable placeholder instead of guessing a plausible-sounding number and hoping you notice. You always know exactly what was assumed. • You stay in control. Keen rewrites your prompt in place and lets you review it before sending. Nothing goes out on your behalf without you seeing it first. Works on Claude, ChatGPT, Gemini, and Perplexity. One click, one clear rewrite, every time.
