Omnidetect
OmniDetect analyzes text for AI-generated passages and shows the evidence, uncertainty, and limits behind its verdict. Writers and reviewers can use the results to decide what to revise and re-check before submitting or publishing.
Who it's for
- Students or academic writers checking essays before submission, as supported by the academic essay text type and pre-submission workflow.
- SEO and marketing teams reviewing blog posts or marketing drafts for AI-likelihood signals.
- Professionals reviewing business communications or technical writing, both listed text types in the detector.
Not the right fit if…
- People who need to analyze more than 2,000 characters without signing in: the free guest preview covers only the first 2,000 characters.
- Teams needing to paste more than 50,000 characters in one analysis: the described paste workflow has a 50,000-character limit.
How it fits your workflow
Paste text, upload a PDF, DOCX, or TXT file, or scan a URL. The page describes pasting up to 50,000 characters; guest users receive an analysis of the opening 2,000 characters, while a free account covers the whole document.
OmniDetect selects a detection engine based on the text's language and its own benchmark. The result presents a verdict alongside the passages, method information, evidence, and known limits.
If a complete result confidently flags passages, review the suggested focused rewrites and re-check the revised text. The page says re-checking uses the same Word Token balance.
