Step-by-step guide
Copy the text you want to check
Grab the essay, article, message, or paragraph you're unsure about. For the most reliable score, use at least 100 characters (roughly 15+ words).
Paste it into the detector
Open the AI detector and paste your text into the box. No account, sign-up, or payment is required.
Click “Detect AI”
The detector analyzes your text sentence by sentence. Most checks finish in a few seconds; longer text can take a little more time.
Read your 0–100 score
You'll get an overall AI score with a clear label — Likely human, Mixed signals, or Likely AI — so you can interpret the result at a glance.
Review the highlighted sentences
Sentences with the strongest AI signals are highlighted on your text, so you can see exactly which passages to reread or revise.
Usage tips
- Submit at least 100 characters — short snippets are unreliable and get pulled toward the middle.
- Check a longer, connected passage rather than a single sentence for a steadier result.
- Remember the score is a probability, not proof. Detectors can flag human writing as AI.
- If you're revising, treat highlighted sentences as cues to add specific detail and vary your sentence length.
Who it's for
Students
Sanity-check your own writing before you submit, and understand why a passage might look AI-generated.
Educators
Use a score to start a conversation and a closer look — never as automatic proof of misconduct.
Writers & editors
Audit drafts, ghostwritten copy, or AI-assisted content before publishing.
