Step-by-step guide to detect ai generated text online free:
Open the AI Content Detector
Click the "Open Tool" button to launch the FixTools AI Content Detector.
Paste your text
Copy and paste the text you want to analyze into the input field. For best results, use at least 200 words.
Run the detection
Click the "Detect" button. The tool will analyze the text and return an AI probability score within seconds.
Review the results
Read the confidence score and any highlighted phrases. Use this alongside your own judgment to decide how to proceed.
Common situations where this approach makes a real difference:
Freelance client review
A content manager receives an article from a contractor and wants to confirm it was written by a human before approving payment.
HR pre-screen
A recruiter scans cover letters and writing samples to identify candidates who submitted AI-generated responses instead of original writing.
Publisher quality gate
A blog editor runs incoming guest post submissions through the detector as part of an editorial checklist before publishing.
Use this when you need to quickly verify whether a document, article, or submission was written by AI. Ideal for a fast, no-friction check before taking further action.
Get better results with these expert suggestions:
Test with longer passages
The detector is more accurate with 200+ words. Short snippets may produce inconclusive results because there is less pattern data to analyze.
Check the highlighted sections
Pay attention to which specific sentences are flagged. AI text often shows uniform sentence rhythm and overly neutral phrasing that stands out.
Use as one signal, not the final verdict
AI detection is probabilistic. Combine the score with your own reading judgment before drawing conclusions about authorship.
