The workflow is deliberately short: copy AI-generated text from ChatGPT, Claude, Gemini, Grok, DeepSeek or another assistant, paste it into the humanizer, and click Write Human. Within seconds the tool returns a rewrite that varies sentence length, swaps rigid phrasing for everyday word choices and restructures prose, while keeping the original facts and claims intact. The product is more than a single rewriter. A built-in detector scores drafts sentence by sentence with an AI probability, flagging anything above roughly 60% as likely machine-written and anything under 40% as reading human, so you can see exactly which lines need another pass. There is also an AI image detector, a word counter, a Chrome extension that works in any tab, mobile apps, and an MCP server so AI agents can call the humanizer directly. This makes WriteHuman usable for long-form articles, marketing copy, client deliverables, business communications and newsletters rather than just short snippets. WriteHuman operates a freemium model. The free tier gives 3 humanization requests a month at up to 250 words each with basic quality, while Basic, Pro and Ultra plans raise request limits, word caps, output variations and detector checks, and add priority support. A separate API tier is priced per word for teams building on top of the engine. WriteHuman describes itself as an independent tool and is not affiliated with the detectors it is compared against; results depend on how those third-party detectors score text at any given moment. **Pricing & Plans:** Freemium. The free plan allows 3 humanizer requests/month up to 250 words with basic quality and 10 detector checks. Paid plans bill annually at $12/mo (Basic, 80 requests), $19/mo (Pro, 200 requests, MCP access) and $39/mo (Ultra, unlimited requests, 1,000 MCP calls/mo); monthly prices are $20/$29/$59. A word-priced REST API is sold separately. Cancel anytime and switch plans freely. - **AI humanizer:** Paste text from any AI writing tool and get back a rewrite with more natural rhythm, varied sentence lengths and less formulaic word choices, while keeping the original meaning intact. - **Built-in AI detector:** Score your draft sentence by sentence so you can see which lines read as human, which are borderline, and which still read as machine-written before you publish. - **AI image detector and word counter:** Check whether an image looks AI-generated, alongside a word and character counter for quick draft checks. - **Chrome extension, mobile apps and MCP:** Humanize and fix writing in any browser tab with the Chrome extension, and use mobile apps plus MCP access to reach the same engine from your phone or your AI agents. - **Developer API:** A REST endpoint with word-based pricing, 40+ language support and code examples in JavaScript, Python and cURL for automated pipelines. **Strengths:** Very short workflow: paste text, click once, get a publishable rewrite; Sentence-level AI probability scores make it easy to spot problem lines; Broad integration surface as a Chrome extension, mobile app, API and MCP server; Covers 40+ languages for multilingual content teams **Limitations:** AI-detector outcomes are never guaranteed, since detectors keep updating their models; Free tier is only 3 requests per month with a 250-word cap and basic quality; Output quality varies by language and by how formulaic the source text is; Unlimited plans still cap the words per single request [Profile (Markdown)](https://openaitools.app/tool/writehuman.md) ## ZeroGPT ZeroGPT is best known as an AI content detector, but the site has expanded into a full writing and verification toolkit. The core AI/GPT detector lets you paste text or upload a file and returns a highlighted analysis showing which sentences look machine-written, with a percentage gauge and an automatically generated PDF report you can use as documentation. Around that core sit several companion detectors and writers. The AI image detector and AI video detector extend checking beyond text; the plagiarism checker scans against billions of sources; and the AI humanizer and paraphraser rewrite text into a more natural style. A grammar checker, summarizer, translator, dictionary, word counter, citation generator, and AI email helper round out day-to-day writing tasks. The company says its multi-stage DeepAnalyse model is trained on internet text, educational datasets, and proprietary synthetic AI datasets, covers over 35 LLM families, and reports 98.4% detection accuracy with a false positive rate under 1%. Access is freemium: the main tools work free in the browser, with MAX and EXPERT subscriptions for heavier use and premium features, and a separate API for organizations that need large-scale integration. ZeroGPT also runs on WhatsApp and Telegram through a bot, letting you chat, detect AI text, summarize, paraphrase, translate, and check grammar without leaving the messaging app. **Pricing & Plans:** Freemium with paid tiers. Core tools such as the AI detector, summarizer, and grammar checker are usable free in the browser, while MAX and EXPERT subscriptions unlock higher limits and premium features, and API access is sold separately for organizations. - **AI and ChatGPT detection:** Paste up to 15,000 characters or upload a file and get a highlighted breakdown of which sentences appear AI-written, plus an overall percentage score and a downloadable PDF report. - **AI image and video detection:** Beyond text, ZeroGPT offers an AI image detector and an AI video detector that performs frame-level analysis to flag generated or manipulated visuals. - **Plagiarism checking and humanizing:** Compare your text against billions of sources through the plagiarism checker, or rewrite and humanize AI text with the paraphraser and AI humanizer while keeping the original meaning. - **Writing and productivity tools:** A bundled writing suite covers summarization, grammar and spelling correction, translation across many languages, a dictionary, word and character counting, citation generation, and an AI email writer. - **API for organizations:** A documented REST API exposes detection, plagiarism, paraphrasing, summarization, grammar, chatbot, and translation endpoints for organizations that need to embed ZeroGPT at scale. **Strengths:** Free browser access to the core AI detector, summarizer, and grammar checker; Sentence-level highlighting with an overall percentage and exportable PDF reports; Extends beyond text to AI image and video detection, plus plagiarism checking; Broad companion toolkit: humanizer, paraphraser, translator, dictionary, citations, email helper **Limitations:** AI detectors can produce false positives, so results should be treated as a signal rather than proof; The strongest features sit behind MAX/EXPERT paid tiers and API access is a separate purchase; Character limits apply to the free detection box; No detection tool can guarantee correctness across every model and language [Profile (Markdown)](https://openaitools.app/tool/zerogpt.md) ## Frequently Asked Questions ### How do WriteHuman and ZeroGPT compare in monthly traffic?
