Looking for a free AI detector for your homework? Most AI detection tools like GPTZero, Originality.ai and Turnitin charge per scan or require a monthly subscription. This one reads the first 1,500 words of any document free, with no sign-up and no credit card, and checks a full document of up to 30,000 words for €4.99 once rather than every month. Teachers and professors increasingly use AI detection tools to check homework submissions. Whether it is a weekly assignment, a book report, or a longer project, our free AI detector helps you verify your work before handing it in. The tool analyzes your homework across 16 key dimensions to identify patterns associated with AI-generated text. Even shorter assignments of 300-500 words can be checked, though longer texts provide more reliable results. Running a quick check before submission takes just seconds and can save you from uncomfortable conversations about academic integrity.

Why Check Your Homework for AI?

Teacher Tools

Many teachers now use AI detection as a routine part of grading. Your homework may be scanned before it is even read.

Quick Check

It takes just seconds to upload and check. The peace of mind is worth the minimal effort.

Learning Opportunity

Understanding how AI detection works helps you become a more aware and effective writer.

Academic Standing

Even minor assignments can trigger academic integrity reviews if AI is detected.

How We Detect AI in Homework

  • Sentence Length Uniformity: AI homework answers have suspiciously consistent sentence lengths.
  • Vocabulary Diversity: Your natural vocabulary should shine through in your assignments.
  • Burstiness: Human writing varies in complexity. AI stays flat.
  • AI-Characteristic Phrases: We check for 60+ known AI-favored expressions.
  • Transition Word Frequency: AI overuses transitions even in shorter texts.
  • Paragraph Uniformity: Even in shorter assignments, AI produces uniform paragraph lengths.
  • Passive Voice Usage: AI uses more passive voice than typical student writing.

Tips for Your Homework

  1. Write in your own words, even if the answer seems simple.
  2. Include examples from class discussions or personal experience.
  3. Do not over-formalize short assignments. Write naturally.
  4. If you used any AI tools for help, disclose it per your school's policy.
  5. Read your answer aloud - if it sounds like a robot, revise it.

Frequently Asked Questions

The first 1,500 words are free, with no sign-up, no credit card and no cap on how often you run it. Unlike GPTZero, Originality.ai or Turnitin, checking a full homework is a single €4.99 payment rather than a subscription - and it includes 14 days of unlimited re-checks.
The free tier covers your first 1,500 words, which is enough to check an abstract or a chapter and not enough to check a thesis - that is the paid check, at €4.99 once. We keep the free tier genuinely useful because it is how people find us, and because a student who cannot pay should still be able to see what a detector sees.
Our tool uses similar statistical analysis methods as paid tools. While paid services may offer additional features like plagiarism checking or API access, our core AI detection analysis is comprehensive and effective for individual document checks.
Many do, especially for writing assignments. AI detection tools are becoming standard in both K-12 and university settings.
Yes. Our tool works on any length, though texts under 300 words provide less statistical data for analysis.
Policies vary, but generally: generating full answers with AI is not allowed, while using AI for grammar checking or brainstorming may be acceptable. Check your school's specific policy.
