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) ## SmartProxy SmartProxy is a proxy and web data infrastructure provider built around a large residential IP pool. The network spans more than 100 million IPs across over 200 countries, with country, state and city-level targeting. Requests are routed through real residential IPs with smart rotation, so data collection jobs keep high success rates on sites that block datacenter traffic. Beyond standard rotating residential proxies, SmartProxy offers unlimited residential traffic, static residential proxies, long-acting ISP proxies and static datacenter proxies. These cover different trade-offs between speed, stability, and cost per gigabyte or per IP. Scraping APIs and prebuilt scrapers extend the platform to teams that would rather buy extracted data than operate their own scraping stack. SmartProxy positions itself as AI-ready infrastructure. Common workloads include feeding clean data into LLM and automation pipelines, ad verification across regions, price monitoring, market research, e-commerce intelligence and social media account management. The platform integrates with Python, Node.js, Java, Go, PHP, C#, Ruby and Rust, and every plan includes a real-time dashboard and 24/7 technical support. The legacy smartproxy.org domain now redirects to the company's official smartproxy.ai site. **Pricing & Plans:** Free trial plus paid, usage-based plans. Traffic-based products (residential, unlimited, ISP) are billed per GB, while static residential and datacenter proxies are billed per IP. The site advertises no hidden fees and predictable costs; confirm current rates on the official site. - **Residential proxy network:** Route requests through real residential IPs with smart rotation and free geolocation for higher scraping success rates. - **Multiple proxy types:** Choose unlimited residential traffic, static residential, long-acting ISP, or static datacenter proxies depending on your workflow. - **Web scraping APIs:** Dedicated scrapers and APIs for web data collection, plus integration guides for AI and automation platforms. - **Global targeting:** Target locations at country, state and city level, with detailed per-country pools such as Brazil, India, the US, Turkey and Mexico. - **Dashboard and support:** Real-time usage monitoring, detailed analytics, 24/7 technical support and an enterprise-grade SLA. **Strengths:** Large residential pool with 100M+ IPs in 200+ locations; Several proxy types to match different cost and speed needs; Scraping APIs and integrations for major programming languages; 24/7 support and real-time usage monitoring [Profile (Markdown)](https://openaitools.app/tool/smartproxyorg.md) ## Frequently Asked Questions ### How do GPTZero and SmartProxy compare in monthly traffic?
