ZeroGPT review
A free, API-oriented detector with detailed text analysis and broad file support.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ZeroGPT is an AI content detection platform for educators, students, content creators, publishers, SEO professionals, marketers, researchers, and businesses. It analyzes pasted text and uploaded documents to estimate whether content was generated by AI models including ChatGPT, GPT-5, Claude, Gemini, and DeepSeek. Its free plan and API access make it particularly relevant for teams that need detection in a workflow rather than only in a browser. Sentence-level analysis adds probability scores that help users inspect specific passages instead of relying only on a document-wide result.
The product’s strongest fit is its combination of document support and developer features. Users can upload TXT, DOCX, PDF, and ODT files, while the REST API supports automated detection. Webhooks can provide detection events and usage alerts, which suits applications that need status updates or usage monitoring. Premium users also receive batch file processing. Alongside detection, ZeroGPT includes plagiarism checking, AI text humanization, and image detection, giving it a wider content-review scope than a narrowly focused text detector. The tradeoff is that its listed integration is Google Docs, so organizations looking for a broader connected ecosystem may find the platform less suitable.
ZeroGPT is a practical choice for users who want a free starting point, sentence-level results, multiple document formats, and an API for automated checks. It can serve both individual content review and application-based workflows, with premium processing features available for larger batches. Buyers should choose an alternative if they need extensive integrations or a product focused only on detection without adjacent tools such as plagiarism checking and AI text humanization. For API-oriented detection with flexible file handling, ZeroGPT offers a clear feature mix.
