DetectGPTVerified tool

DetectGPT is a browser-based AI content detector for reviewing a finished draft or a public webpage. It evaluates whether text sounds machine-generated and presents an AI percentage alongside passage-level signals to help users review their writing.

What it does

Checks pasted text of up to 5,000 words per run for AI-like writing patterns.

• Analyzes public URLs, including homepages, articles, and public posts; login-protected pages and PDFs are not supported for URL scans.
• Produces an AI percentage intended to describe the share of prose that appears machine-made, rather than proof of authorship or a misconduct determination.
• Provides a separate plagiarism-checking option for public-web overlap, with matching phrases and source links described in the report.

Key features

• No account or login required for AI checks.
• Supports text from ChatGPT, Claude, Grok, Gemini, and other language models, as well as human-written text.
• Highlights passages in yellow, orange, and red to show lines that may sound AI-generated.
• Lets users hover over a red sentence to see why it scored that way, then revise and rescore the draft.
• Allows users to share a result link.
• Offers unlimited checks with no stated daily cap, while maintaining a 5,000-word limit per run.
• States that checks stay on the device. What makes it different DetectGPT focuses on the completed draft rather than access to a user's AI account or original prompt. Its report is designed to pair an overall percentage with highlighted lines so users can review specific wording instead of relying only on a single score. The service notes that its detection is strongest for English and that its output is about writing style, not proof of authorship.
