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 [Profile (Markdown)](https://openaitools.app/pt/tool/gptzero-me.md) ## SyncStudy SyncStudy is an AI study workspace that turns your own notes, PDFs, slides, videos and Google Drive files into lessons, spaced-repetition flashcards, graded quizzes and timed mock exams, all organised inside study spaces with plans and progress analytics. **Preços e planos:** Freemium. Free forever plan with 3 study spaces and 10 AI credits a month; Basic at $12/month with 150 credits, full lessons, summaries and web research; Pro at $20/month with 350 credits, unlimited spaces and materials, and Exam Mode. Yearly billing available and Basic includes a 7-day free trial. Free plan requires no card. - **Material import from almost anywhere:** Import PDFs, Word docs, PowerPoint, Excel, pasted text, YouTube videos, web links and Google Drive files into a single study space, with OCR for scanned PDFs. - **Learn, review, teach back, test:** Four study modes built from the same material: guided lessons, spaced-repetition flashcards, out-loud teach-back sessions and adaptive practice tests. - **AI grading and adaptive practice:** Written answers get graded by AI and quiz difficulty adjusts to how you are actually performing, so weak topics get repeated more often. - **Exam Mode with timed mocks:** Pro builds question banks and timed mock exams for targets like NCLEX-RN, MCAT, USMLE Step 1, the CPA Exam and CompTIA Security+, then points you at the areas to revisit. - **Study plans, streaks and analytics:** Tracks streaks, study minutes, cards reviewed and per-space mastery so you can see whether a routine is actually sticking. **Pontos fortes:** Turns existing PDFs, slides and lecture videos into study material without retyping; Four distinct study modes cover recall, comprehension and exam pressure; Generous free tier with no credit card needed; Transparent credit pricing — every AI action's cost is published **Limitações:** Free plan's 10 monthly credits are quickly spent on decks, quizzes and guides; Unused credits do not roll over between billing periods; Exam Mode, the strongest feature for serious test prep, is locked to the most expensive plan; File uploads capped at 30-50 MB, so very large textbooks must be split [Profile (Markdown)](https://openaitools.app/pt/tool/syncstudy.md) ## Perguntas frequentes ### Como GPTZero e SyncStudy se comparam em tráfego mensal?
