How to Use a Free AI Detector and Interpret the Result

A free AI detector can help you review text for patterns associated with generated writing. It cannot certify authorship, guarantee an outcome in another tool, or replace checking facts and sources. This guide explains a practical first scan using AI Detect; the free AI detector page provides the tool and current product details.

What is included in the free plan?

AI Detect's free plan currently allows five detection scans per day, with up to 750 words per scan. The service applies usage controls, so availability depends on your remaining allowance. Paid plans and their limits are listed on the pricing page.

Free detection checks use pasted text. Document uploads and humanization require a paid plan. Follow the allowance and sign-in messages shown in the tool.

Prepare a useful passage

Use a coherent passage rather than unrelated sentence fragments. Preserve the exact text if you need to compare the result later. Avoid uploading confidential material unless you have permission and have reviewed the privacy policy.

If a document exceeds your word allowance, a scan of one excerpt is a result for that excerpt. It does not automatically describe the untested remainder. Do not add or remove content solely to manufacture a preferred classification.

Run the check

Open the AI detector, paste eligible text into its input, and choose Detect AI. Wait for the service to return a result. If it reports an error, the scan has not produced a reliable score; retry when the service is available.

Read the score explanation together with the text. AI Detect also displays readability and grade-level information. These reading-difficulty measures are not evidence of whether AI was used.

Interpret the result cautiously

A detection score is a model signal rather than proof of the writing process. It should not be read as the exact percentage of words written by a machine. Tools may use different definitions, so their numbers are not directly interchangeable.

Both false positives and false negatives are possible. A high-risk result should lead to a closer review of sources, drafts, and context. A low-risk result does not establish that claims are correct or citations are genuine. Read the methodology and our guide to detector accuracy for more detail.

A simple review worksheet

• Record the tool, scan date, and exact passage.
• Note the score without turning it into an authorship verdict.
• Check important facts and references independently.
• Review drafts or source notes when authorship matters.
• Decide on a proportionate next step, such as an editorial check or a conversation with the writer.

For example, an editor who sees an unexpected score might ask for source notes and inspect unsupported claims. The same score would not, by itself, justify accusing a freelancer of violating a contract.

When should you consider a paid plan?

Consider a paid plan if the documented word limits, daily usage, or included features fit a recurring workflow. Check the normal renewal price and billing interval, not only the introductory offer. A paid allowance does not turn an uncertain detector result into proof.

If you only need a small number of eligible scans, start with the free tool and judge whether the workflow helps you review writing more carefully.
