Product guide
An AI detector tool that fits your review.
AI Detect combines a text check with readability and grade-level estimates. Paste a draft, or upload a supported document on a paid plan, review the result, and decide what needs closer attention. This guide explains the workflow and the limits you will see in the tool.
- Text input; paid file uploads
- Readability alongside detection
- Free and paid scan allowances

Detection Score
Higher means a stronger AI writing signal. This is an estimate, not proof of authorship.
Readability
Rates how easy the text is to read on a scale from 0 to 100 — higher scores mean easier reading.
Grade Level
Indicates the U.S. school grade level needed to understand the text — higher education levels mean more complex reading.
A practical workflow
From document to review
- 01
Prepare the text
Use the passage you want to review, without unrelated boilerplate. When uploading a document, inspect the extracted text before scanning.
- 02
Run the detector
The tool displays your word count and allowance. The free scan limit is 750 words; paid tiers increase that limit to 1,000 or 1,500 words.
- 03
Use the right result
Read the detection score as an estimate of writing patterns. Use readability and grade level to discuss clarity, not authorship.
Which features are available?
The tool supports direct text entry. Document upload is available on paid plans. It returns a detection score and separate reading-ease and grade-level estimates. Signed-in users can access recent history. Paid plans also include a humanizer with its own daily allowance. Check the pricing page for the current limits and billing options.
Choose capacity for your actual documents
Beginner supports up to 750 words per scan and 100 daily scans. Pro supports 1,000 words and 150 daily scans; Ultimate supports 1,500 words and 500 daily scans. These are limits, not unlimited plans. Split longer documents at logical section boundaries and review each result in context.
Frequently asked questions
Does AI Detect highlight each AI-written sentence?
The current tool provides a score for the submitted passage. It does not provide a verified authorship determination for individual sentences.
Do I need to install software?
No. AI Detect runs in your browser. You can open the detector and use the available free allowance without installing a browser extension.
Can a paid plan guarantee a more accurate verdict?
No. Paid plans increase capacity and provide additional features. A paid subscription does not turn a probabilistic detection result into proof.
