Suppose you’re about to publish a blog post. One paragraph sounds familiar, a statistic needs a source, and you’re wondering whether part of the draft was generated by AI. These are three different questions. Originality.ai gives you a separate check for each one.

What Is Originality.ai?

Originality.ai is a web-based tool for reviewing written content. Its best-known feature is its AI detector, but it also offers plagiarism, fact-checking, readability, and grammar tools. If you publish articles or review drafts from several contributors, you can use it to decide which parts of a draft deserve a closer look.

What Can It Check?

• AI detection. The detector looks for patterns associated with AI-generated writing and highlights passages for review.
• Plagiarism. The checker compares your draft with publicly available web content and links to matching sources. A match might be a properly attributed quotation, a common phrase, or a passage that needs a citation. Open the source and check the context.
• Fact-checking. The tool flags claims you may want to verify. If a draft says a program launched in 2019, for example, check the date against the organization’s own announcement or annual report.
• Readability. A readability score gives you a rough sense of how easy a draft is to read. Use it to spot sections worth revisiting, then judge whether the wording suits your audience.

What Does the AI Score Mean?

The score reflects how the detector classifies the writing. Human-written text can be flagged, and AI-generated text can pass a scan. A highlighted sentence is a place to look more closely. If authorship matters, drafts, notes, and revision history can give you more context about how the piece came together. Originality.ai’s guide to reviewing flagged text explains what to look for.

How to Try It

Start with a blog post you’ve already published and know well. Paste it into the scanner and review the highlighted passages. Do they point to anything you would actually investigate or edit? Trying the tool on familiar writing gives you a better feel for what the results mean before you use it on someone else’s draft.
