Can I check blog posts that are already published?

Yes. You can paste any text into the detector, including published content. This is useful for auditing existing blog archives for AI-generated posts.

How long should a blog post be for accurate detection?

Posts of 500+ words give the detector enough data to produce reliable results. Shorter posts may show less consistent scores.

Should I disclose if my blog uses AI writing?

Disclosure policies vary. Google does not require disclosure but does value helpful, original content. Many brands proactively disclose AI use as part of their editorial transparency policies.

How to use this tool

💡

Paste the full blog post text. The detector returns a section-by-section AI analysis so you know exactly which parts to send back for revision.

How It Works

Step-by-step guide to detect ai in blog posts:

1
Receive or draft the blog post
Get the final or near-final version of the blog post you want to check.
2
Paste into the AI detector
Open the FixTools AI Content Detector and paste the full blog post text.
3
Review section-level AI scores
Identify which paragraphs have the highest AI probability scores.
4
Request revisions or humanize flagged sections
Send flagged sections back to the writer or run them through the AI Text Humanizer before publishing.

Real-world examples

Common situations where this approach makes a real difference:

Freelancer deliverable review

A content manager receives 10 blog posts from a freelance writer and checks each through the detector before approving payment and publishing.

Guest post editorial review

A tech blog with a "no AI content" policy checks every guest post submission through the detector before sending to editors for topic review.

Agency content audit

A brand manager audits three months of agency-delivered blog content to assess compliance with their human-written content contract requirement.

When to use this guide

Use this before publishing any blog post — particularly those written by freelancers, guest contributors, or content agencies — to ensure the article meets your human-written content standards.

Pro tips

Get better results with these expert suggestions:

Check intros and conclusions separately

Blog writers often use AI most heavily in introductions and conclusions while writing the body manually. Isolate these sections for a targeted check.

Build a content brief before ordering

Detailed briefs with specific examples, data points, and personal anecdotes required make it harder for writers to rely on AI output without customizing heavily.

Set an AI score threshold in your style guide

Define an acceptable AI probability threshold (e.g., below 25%) in your editorial policy so writers know the standard before submitting.
