WriteHuman

WriteHuman rewrites AI generated text so that it reads as if a person wrote it. Output from ChatGPT, Claude, Gemini, Grok, DeepSeek or any other assistant is pasted in, and the rewriter varies sentence length, word choice and cadence while keeping the original meaning intact, returning a version without the uniform rhythm of model prose. A built in detector sits alongside it and scores each sentence for AI probability, so a draft can be checked line by line before it is published. It is aimed at writers, students, marketers and anyone publishing longer work produced with model assistance. Articles, blog posts, marketing copy, emails, landing pages, newsletters and reports are all supported, in more than forty languages. A browser extension for Chrome, Edge, Brave and Arc puts a grammar checker and the humanizer into any text box on the web, including Gmail, Outlook, LinkedIn, Notion and Slack, marking spelling, grammar and style issues in place. An image detector and a REST API with word based pricing are also offered, and paid plans include MCP access. A free tier allows three humanizer requests a month at up to 250 words each, with ten detection checks. Basic is $20 per month for 80 requests at up to 600 words each, Pro is $29 per month for 200 requests at up to 1,200 words, and Ultra is $59 per month for unlimited requests at up to 3,000 words. Annual billing lowers those to $12, $19 and $39 per month respectively. Plans can be changed or canceled at any time.
