## GPTZero

GPTZero is an AI detection platform for identifying machine-generated text. It combines a text detector with a Chrome extension, a plagiarism checker, writing-process verification, and educator-focused classroom tools.

**Preços e planos:** Freemium plus paid plans. A free tier provides core detection with character limits per scan, while paid individual and institutional plans unlock advanced scan modes, higher limits, writing reports, and classroom integrations. Enterprise and API access are quoted separately.

- **Sentence-level AI detection:** Paste text or upload a document and get an overall AI probability score plus a sentence-by-sentence breakdown of which parts look machine-written.
- **Multi-model coverage:** Flags AI text from major model families including ChatGPT, Gemini, Claude, Llama, and others, rather than training for a single model.
- **Browser and docs extensions:** A Chrome extension and Google Docs add-on bring scanning into Gmail, Docs, Classroom, and other surfaces you already work in.
- **Plagiarism checking:** Checks content for copied passages from outside sources so you can separate AI-generation questions from originality questions.
- **Writing process verification:** Writing replay and advanced reports offer evidence about how a document was produced, useful for academic integrity workflows.

**Pontos fortes:** Sentence-level highlighting shows why a passage was flagged instead of only giving a score; Covers text from many different AI model families, not just one chatbot; Integrations with Chrome, Google Docs, Canvas, and Google Classroom fit existing school workflows; Publishes concrete compliance claims (SOC 2 Type II, FERPA, GDPR, CCPA) that institutions can review

**Limitações:** Detection is probabilistic and can flag polished human writing or miss lightly edited AI text; Free scans are capped by character count, and useful reporting features require payment; Lean heavily on a single score without human judgment can lead to unfair accusations

## WriteHuman

WriteHuman is an AI humanizer and detection suite. It rewrites text produced by ChatGPT, Claude, Gemini, Grok, DeepSeek and similar tools into natural, human-sounding prose, and includes an AI detector, an AI image detector, a word counter, a Chrome extension and a REST API for developers.

**Preços e planos:** 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.

**Pontos fortes:** 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

**Limitações:** 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
