AI Detector for Blog Posts

Updated

An AI detector for blog posts gives editors and site owners a quick signal on long-form web content. Paste an article of 300 words or more, up to 150,000 characters, to see a probability that it reads as AI-generated and which sentences drive the score.

Limitations: Every result is a probability that can be wrong, not proof of how something was written. How results can be wrong →

When to Use an AI Detector for Blog Posts

  • Freelance submissions: if your brief says no AI-written drafts, a score is one way to start a conversation with a writer.
  • Guest posts: unsolicited guest posts are a common place for mass-produced text.
  • Your own drafts: flagged sentences often point to filler paragraphs that add nothing for readers.
  • Content audits: spot-check older articles before updating them.

What Google Says About AI Content

Google's public guidance focuses on whether content is helpful and made for people, not on how it was produced, while its spam policies target content mass-produced mainly to rank. A detector score doesn't tell you either of those things.

So use the score as an editorial prompt. A post that scores low but says nothing new can still be thin; a post that scores high but is accurate, original and useful may be fine.

Editing Tips for Flagged Posts

Flagged passages are often the generic introduction, the listicle middle and the summary conclusion. Replace them with first-hand detail: what you tested, the numbers you saw, the screenshot you took, the mistake you made.

Check facts in any AI-assisted section. Invented statistics and sources are a bigger risk to your site than a detector score.

Checking Older Posts Before an Update

Content teams refreshing old articles sometimes find posts from past contractors that read as generic. Checking them before an update shows which sections need the most rewriting, so editors can spend time where it adds the most value for readers.
