AboutGPTZero
GPTZero is a dedicated AI content checker that recognizes machine-generated text in any document. This powerful proprietary model helps you identify exactly which parts of a text originated with a large language model (LLM).
How does it work? It analyzes text for key patterns that distinguish machine writing from human writing. These factors include checking for predictability (perplexity), variation in sentence structure (burstiness), and whether the tone is overly generic or repetitive.
Since its founding in January 2023, GPTZero has quickly become essential. It has served over 10 million users and is used by hundreds of institutions, especially in education. It is truly built for contexts where authentic and quality writing matters most. 💡

Core Purpose & Scope
GPTZero is a specialist detector; Writer is a versatile AI platform.
GPTZero is a dedicated AI content checker and integrity validation tool. Its singular focus is identifying machine-generated text in documents. This specialization is ideal for academic and publishing integrity uses. Writer is a comprehensive AI content platform designed for modern enterprise teams. AI detection is only one key tool, integrated with agent building and content governance. Writer emphasizes scaling AI across the organization quickly. GPTZero is the specialist detection tool, focusing purely on analysis. Writer is a versatile foundational platform offering creation and management features.

Detection Accuracy
GPTZero offers verified 99% accuracy; Writer focuses on quick checks.
Independent studies confirm GPTZero maintains a verified 99% accuracy rate. It features a low 1% false positive rate even for non-native ESL writers. GPTZero performs deep analysis checking perplexity and burstiness. Writer functions as a quick verification and quality check before content publication. Users can check documents up to 5,000 words fast using text or URL input. Writer reliability feedback is currently limited and mixed in existing user reviews. GPTZero offers quantifiable, specialized accuracy required for high-stakes verification.
Pricing Model
GPTZero is word volume-based; Writer is per-user seat cost.
GPTZero pricing scales based strictly on the scanned word volume ($8.33-$24.99/month base cost). This model suits high-volume content operations and prolific reviewers. The Professional plan offers a huge 500k word base limit. Writer charges per user seat, starting at $29/user/month with an annual commitment. This better handles stable teams with predictable headcounts. The Starter plan strictly caps the team size at 20 users. Choose volume limits if you are a solo high-volume writer. Choose Writer if you prefer a static per-user cost for your team.
Custom AI Agents
Writer builds custom agents; GPTZero has zero agent functionality.
GPTZero does not offer any functionality for building custom AI agents. Its feature set is strictly limited to content verification and analysis tools. Writer’s Starter plan includes full AI Studio access and allows building up to five custom agents. Enterprise users can deploy large fleets of custom agents with robust controls. Writer is actively built for AI content generation and workflow structure. GPTZero is purely a reactive analysis tool only.
Feedback Transparency
GPTZero explains the detection; Writer gives a simple score.
GPTZero offers advanced interpretability and transparency for flagged text results. It uses natural language to explain exactly why passages were flagged as AI. Results feature detailed color-coded highlights down to the sentence level. Writer provides a clear verification score for content authenticity. However, detailed, sentence-level analysis insights are not explicitly documented. GPTZero provides superior educational and diagnostic feedback for editing and review.
Customer Support
Writer offers priority support; GPTZero support is widely reported as unresponsive.
GPTZero user reviews frequently report unresponsive and inadequate customer support. There are widespread complaints about confusing cancellation procedures and non-transparent billing. Writer explicitly includes expert onboarding and priority support service in its Enterprise plan. Writer currently boasts a much higher overall user rating (4.3). Writer offers better dedicated support for paying customers, mitigating risk.
Team Scaling
GPTZero handles massive word volume; Writer handles organizational structure.
GPTZero's Professional plan handles huge word volumes (500k base) and batch files. Scaling focuses on content limits, not user count. Writer’s Starter plan is capped at 20 users, forcing growth into the Enterprise plan. Writer is built for organizational governance and includes custom strategy and support. GPTZero is better for solo high-volume writers or institutions. Writer offers clear structural paths for organization growth.
Data Integration
Writer grounds AI in your custom data; GPTZero offers standard security.
GPTZero’s Professional plan includes standard enterprise-grade security features. Specific compliance details or data grounding capabilities are not generally publicized. Writer includes enterprise-grade security across both Starter and Enterprise plans. It allows grounding AI models securely in company data using the Knowledge Graph feature. Writer provides a secure context layer for AI generation, enhancing security and relevance.
