Humanize text. Check for AI-style writing. Make it sound more like you. AI Humanizer brings natural rewriting, an AI Content Detector, and personal Writing Style learning into one simple workflow. Paste your text, check how AI-like it appears, humanize the wording, and recheck the result. Then teach the app your writing preferences to help future rewrites sound more like you. HUMANIZE TEXT, KEEP YOUR MEANING Turn stiff or robotic drafts into clearer, smoother writing. Refine wording, flow, and sentence structure while keeping your original meaning in focus. Use Humanizer for: • Essays and academic drafts • Professional emails and cover letters • Reports and documents • Articles and blog posts • Messages and everyday writing Humanizer aims to preserve names, numbers, facts, citations, and key terminology. Always review the result before using or sharing it. CHECK WITH AI CONTENT DETECTOR Check pasted text before rewriting, or use Recheck AI after humanizing. See an estimated AI-style score with results such as: • Likely AI-written • Mixed • Likely human-written Move directly from checking to Humanize This Text, then recheck your revised wording without switching apps. AI detection is an estimate and can be wrong. Scores are not proof of authorship or a probability that AI wrote the text. Rewriting does not guarantee a particular detector result. CHOOSE FROM SIX WRITING MODES • Natural — conversational and smooth • Academic — polished for essays and academic work • Formal — professional and structured • Clear — simpler and easier to read • Concise — shorter and more direct • Friendly — warm and approachable TEACH IT YOUR WRITING STYLE Your edits help make Humanizer personal. After rewriting, open Teach My Writing Style and edit the result the way you would naturally write it. The app can learn preferences in your tone, word choice, phrasing, and sentence style. For example, you might change “Participants should bring a notebook” to “Bring a notebook!” Your learned preferences can help guide future results. CHECK. HUMANIZE. RECHECK. 1. Paste or type your text. 2. Tap Check AI for an estimated assessment. 3. Choose a writing mode and tap Humanize Text. 4. Tap Recheck AI to check the rewritten result. 5.
