MonkeyPen is an AI text humanizer. You paste text generated by ChatGPT, Claude, Gemini, or any other AI, pick a writing tone, and get back text that sounds like a real person wrote it. No more robotic filler, no more AI slop.
MonkeyPen analyzes your AI-generated text and rewrites it to remove the telltale patterns that make AI writing obvious: em dashes, "delve", "it's worth noting", semicolons, and the formulaic sentence structures that AI detectors look for.
The result reads like a human wrote it from scratch. Same meaning, different voice.
Your text is sent to our API, processed, and returned. That's it. We don't store your text, we don't log your transformations, and we don't use your content for training. Your writing stays yours.
Free users get 5 transforms per day with up to 1,000 characters each. All 6 tones are included.
Pro ($6.99/mo) unlocks unlimited transforms, up to 5,000 characters per transform, and priority processing. Cancel anytime.
