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) ## TopicMojo TopicMojo describes itself as a topic and question research tool combined with a search listener.
