The product answers that with a detector that returns an overall AI likelihood score and highlights individual sentences it considers machine-written, so a reader can see where the suspicion comes from rather than just receiving a single verdict. Over time the platform widened from a single text box into a suite aimed at institutions. Detector results are paired with a plagiarism checker, grammar and writing feedback, and optional process verification such as a writing replay that records how a document was typed. A Chrome extension and Google Docs add-on push detection into the tools students and staff already use, and the company offers classroom integrations plus an API for bulk or programmatic checks. Because the buyers are largely schools, districts, and universities, GPTZero leans heavily on privacy and compliance claims: it states SOC 2 Type II compliance and alignment with FERPA, GDPR, and CCPA, and says student writing is not used to train models. The practical takeaway is that it is positioned as an academic-integrity and editorial-review tool rather than a novelty checker, which also means its more powerful features sit in paid tiers. **Pricing & Plans:** 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. **Strengths:** 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 **Limitations:** 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 [Profile (Markdown)](https://openaitools.app/tool/gptzero-me.md) ## Rewrait Rewrait is a desktop writing assistant built for people who think in one language but need to write in English. Instead of opening a separate document or web page, you work in the app you already use, select the text, and press a keyboard shortcut. A panel appears above your text with a native-sounding rewrite that preserves your original meaning; nothing changes until you accept it.\n\nThe app is available for macOS (14.6 and later) and Windows (10 and later, from the Microsoft Store) and works in Slack, Gmail, Outlook, Teams, Notion, and standard browser fields. Beyond rewriting, it can dictate a message in your own language and return English text, draft replies from the conversation on screen (with anything it added underlined), and give quick tone adjustments like Shorter, More Casual or More Formal. A personalized rules system remembers corrections you make and reapplies them next time.\n\nRewrait emphasizes privacy: it says it does not train models on your writing, and the macOS app is notarized by Apple. Accounts start with 14 days of every feature, and a free plan is available without a credit card to try it out. **Pricing & Plans:** Freemium. A free plan is available with no credit card, and every account starts with 14 days of access to all features. Detailed paid tier pricing is listed on Rewrait's pricing page. - **Rewrite in any app:** Press a shortcut, and Rewrait shows a native-sounding version of your text that you can preview, edit and accept before anything changes. - **Voice input and dictation:** Speak in your own language and Rewrait turns it into English text in the field you're writing in. - **Draft replies from context:** In an empty reply box, Rewrait drafts a reply from the conversation on screen, with added dates and answers underlined for review. - **Style and tone controls:** Adjust the tone with one-key options like Shorter, More Casual, More Formal or Closer to Mine, or describe a change in plain words. - **Personalized correction rules:** Save corrections you make so Rewrait applies your personal rules to future rewrites, scoped to specific apps like Slack. **Strengths:** Works inside the apps you already use, with a single shortcut; Fixes drafts so they read like native English without changing meaning; Includes voice input, reply drafting and tone, not just rewrites; Native Mac and Windows apps with Apple notarization and no training on your writing **Limitations:** Desktop app only (Mac and Windows), no in-browser version; Optimized for English output, less useful if you need to write in other languages; Free plan is limited; full feature access runs for 14 days before requiring a paid plan [Profile (Markdown)](https://openaitools.app/tool/rewrait.md) ## Frequently Asked Questions ### How do GPTZero and Rewrait compare in monthly traffic?
