You’ve just finished writing an important essay, and now you’re worried: Will this get flagged as AI-generated? You may need to paraphrase content, but don’t want it detected by AI checkers. If you’re stuck choosing between QuillBot vs ZeroGPT, you’re not alone. These tools serve completely different purposes—one creates and refines content, the other detects AI writing. Understanding which one fits your needs can save you time, money, and potential headaches. Let’s break down everything you need to know.
Before diving into the details, here’s what you need to know about the QuillBot vs ZeroGPT comparison:
QuillBot’s writing assistant features paraphrasing, grammar, and multiple modes.
Quillbot is an AI-powered writing assistant launched in 2017 that helps users paraphrase, improve grammar, and enhance their writing quality. The platform offers multiple paraphrasing modes, including Standard, Fluency, Formal, Academic, Creative, and the newer Humanize mode designed to make AI text sound more natural. With over 80 million users worldwide, QuillBot has become a go-to tool for students, content creators, and professionals seeking to refine their writing efficiently.
ZeroGPT uses DeepAnalyse™ to detect AI text but has accuracy issues.
ZeroGPT is an AI content detection tool that identifies whether text was generated by AI models like ChatGPT, GPT-4, Claude, or Gemini. Using its proprietary DeepAnalyse™ Technology, ZeroGPT analyzes linguistic patterns, sentence structure, and text burstiness to determine authenticity. The platform provides percentage-based detection scores and highlights specific sentences flagged as AI-generated. However, independent testing reveals significant accuracy concerns, with real-world performance ranging between 35% and 65% despite the company’s claimed 98% accuracy rate.
When comparing QuillBot vs ZeroGPT, understanding their core capabilities helps you choose the right tool for your specific needs. Let’s examine how these platforms stack up across seven critical features that matter most to users in 2025.

ZeroGPT positions itself primarily as an AI detector, yet independent testing reveals concerning accuracy gaps. While the company claims 98% detection accuracy, real-world performance shows only 35-65% reliability, with high false positive rates flagging human-written text as AI-generated.
ZeroGPT’s claimed 98% accuracy is low in real tests.
QuillBot’s AI detector, launched in July 2024, achieves approximately 76% accuracy—lower than ZeroGPT’s claims but more consistent in practice. QuillBot detects raw AI content at 96-98% for ChatGPT and 92% for Claude, though accuracy drops to 85-89% for edited content.
Winner: QuillBot
QuillBot AI detector with 76% consistent accuracy, high for raw AI text.
QuillBot dominates the paraphrasing arena with 10+ specialized modes, including Standard, Fluency, Formal, Academic, Creative, Expand, Shorten, and the innovative Humanize mode. Premium users enjoy unlimited word counts per paraphrase, while free users get 125 words. The platform excels at maintaining meaning while varying sentence structure and vocabulary.
QuillBot dominates paraphrasing with 10+ modes and unlimited premium words.
ZeroGPT offers basic paraphrasing capabilities limited to 2,500-5,000 words monthly depending on your plan, with fewer customization options. The quality difference is substantial—QuillBot’s paraphrasing feels natural and context-aware, whereas ZeroGPT’s paraphraser serves as a supplementary feature rather than a core strength.
Winner: QuillBot
ZeroGPT paraphrasing is basic, limited, and lacks QuillBot’s quality.
Both platforms offer text summarization, but they approach it differently. QuillBot provides 2,500 words for free users and unlimited summarization for Premium subscribers, with adjustable summary lengths and bullet point options. The tool excels at condensing long articles, research papers, and documents while preserving key information.
QuillBot offers unlimited text summarization with adjustable length for premium users.
ZeroGPT offers 5,000-10,000 words of summarization monthly based on your subscription tier. However, QuillBot’s summarizer integrates seamlessly with its other writing tools and works across multiple platforms through browser extensions. The unlimited access for Premium users and superior integration make QuillBot more practical for heavy users.
Winner: QuillBot.
ZeroGPT’s summarizer is limited; QuillBot offers unlimited, integrated access.
QuillBot’s grammar checker supports seven language variants, including US English, UK English, German, French, Spanish, and Portuguese, offering comprehensive corrections for grammar, spelling, punctuation, and style. The tool provides real-time suggestions and works wherever you type through browser extensions.
QuillBot’s grammar checker supports seven languages with real-time corrections.
ZeroGPT includes grammar checking with monthly limits of 5,000-10,000 words, depending on subscription level. While functional, ZeroGPT’s grammar checker lacks the depth and language variety of QuillBot’s offering. QuillBot also provides context-aware suggestions that improve writing clarity and professionalism. The integration across 100+ platforms gives QuillBot a significant practical advantage for daily writing tasks.
Winner: QuillBot
ZeroGPT’s limited grammar checker lacks depth, language variety, and integration.
This category shows ZeroGPT’s strength. While QuillBot limits plagiarism checking to 20 pages monthly on Premium plans, ZeroGPT offers 20,000-40,000 words of plagiarism checking depending on your subscription tier. For users who need extensive plagiarism verification—educators reviewing multiple student papers or content creators checking large volumes—ZeroGPT provides better value.
ZeroGPT offers higher plagiarism check limits (20k-40k words) than QuillBot’s 20 pages.
QuillBot’s plagiarism checker integrates with its writing suite and provides clear, detailed reports, but the page limit can feel restrictive for power users. However, QuillBot’s plagiarism detection quality and database coverage receive positive user feedback.
Winner: ZeroGPT
QuillBot plagiarism checker provides quality reports despite the restrictive page limit.
QuillBot supports 45+ languages through its translation feature and offers paraphrasing in 25+ languages, making it ideal for multilingual content creators and ESL learners. The platform’s grammar checker works across seven language variants with proper regional spelling and grammar rules.
ZeroGPT claims to support all major languages for AI detection and its auxiliary tools, but documentation on specific language support remains limited. QuillBot’s extensive language portfolio and proven track record with multilingual users give it a clear advantage. The ability to translate, paraphrase, and check grammar across dozens of languages in one platform is invaluable for global teams.
Winner: QuillBot
QuillBot shines with integrations across 100+ platforms, including Gmail, Google Docs, Microsoft Word, LinkedIn, Slack, Notion, WhatsApp, and Facebook, through browser extensions, desktop apps, and mobile apps. You can access QuillBot wherever you write, making it seamlessly integrated into your workflow.
QuillBot integrates seamlessly across 100+ platforms via extensions and apps.
ZeroGPT takes a different approach with WhatsApp and Telegram integrations, allowing you to use AI detection and other features through messaging apps. However, ZeroGPT lacks browser extensions and widespread platform integration, requiring users to copy-paste content into their web interface.
