AI detection that shows the passages, the evidence and the misses
Beginner
What is OmniDetect?
OmniDetect is an AI checker tool. An AI content detector that returns passage level verdicts, the method behind them and published accuracy figures, with optional evidence guided rewrites and a free no signup preview of the first 2,000 characters.
OmniDetect is an AI content detector built around a simple premise: a percentage on its own is not useful. The tool scans submitted writing and returns a verdict alongside the specific passages that drove that verdict, the method used to reach it, and the known limits of the analysis. Scores run on a 0 to 100 scale grouped into three bands (0 to 30 likely human, 31 to 70 uncertain, 71 to 100 likely AI), and the site publishes measured accuracy figures including its own misses rather than presenting the detector as infallible. The intended users are writers and students who need to know what to fix before submitting, plus editors and reviewers who want an inspectable basis for a decision. Users can paste text directly, upload a PDF, DOCX or TXT file, scan a URL, or load the built in AI and human sample passages. Writers can tag a detected profile (ESL, non-native, native speaker, professional, grammar-edited) and a text type such as academic essay, SEO copy, creative writing or business email, so the reading accounts for context that commonly confuses detectors. In practice the workflow runs check, understand, improve, re-check. Guests get a real analysis of the first 2,000 characters without signing up; a free account extends coverage to the whole document, and the scanner accepts up to 50,000 characters. Where the result confidently flags specific passages and the analysis is complete, OmniDetect can propose focused rewrites that the user reviews before re-checking the revised text. Among AI detectors, OmniDetect positions itself as the transparent option rather than the harshest one. It publishes head to head comparisons against GPTZero, Turnitin, Originality, Copyleaks, Pangram, Winston, ZeroGPT, QuillBot and Grammarly, maintains an accuracy and benchmarks page, and documents why detectors disagree. Submitted text is stored in a history the user can delete at any time, and the only outside parties that see it are the detection engines doing the analysis.
