Accuracy of Grammarly's AI Detector

Detection Rates

When you use the grammarly ai checker, you want it to find AI content. But the accuracy is not as good as other tools. Many people see that it misses AI-generated text, especially if someone changes or edits it a little. Tests show the grammarly ai checker does not catch as much as top ai content detector tools.

You can look at the table below for the results. These numbers come from new studies and tests by users:

You can also see the detection rates in this chart:

If you compare grammarly ai checker to other ai content detector tools, you will see a big difference. For example, Originality.ai gets an F1 score of 0.918 and an accuracy of 84.84%. Grammarly's ai detection is much lower, with an F1 score of only 0.364 and accuracy of 22.22%. This means you should not use grammarly ai checker for important ai content checks.

You might notice grammarly ai checker gives a high AI score for easy marketing writing. But it has trouble with short or hard texts. The confidence level for 100% AI text is about 37%, which matches what other people say. This low number makes it hard to trust the results.

False Positives and Negatives

You may see grammarly ai checker make both false positives and false negatives. A false positive is when it says human writing is AI. A false negative is when it misses AI writing and calls it human. Both problems are bad for students, teachers, and workers who need good ai content detection.

Here are some common problems you might have:

• Grammarly ai checker has trouble with changed, mixed, or AI-edited writing. It often misses these and gives false negatives.

• Tools like Toolsmart's Undetectable AI Rewriter can make AI writing hard to find, so grammarly's ai detector does not catch it.

• If you rewrite a 300-word AI draft, grammarly ai checker might say it is 0% AI, even if it is still mostly AI.

• Sometimes, the detector marks real human writing as AI, which causes false positives and confusion.

• It is easy to get around grammarly ai checker with rewriting or humanizing tools. This makes it not good for serious school or work use.

Tip: Do not use grammarly ai checker as your only ai content detector. For important work, always check again with a stronger ai content detection tool.

The accuracy of grammarly's ai detector stays low, with about 33% in many user tests. You will see it misses most AI writing, especially if the text is changed or rewritten. This low ai detection accuracy means you should not trust grammarly ai checker for big or important checks.

Limitations

Missed AI Content

Grammarly sometimes does not find some AI writing. Many people say it has trouble with text that sounds like a real person. If you write a short blog post that looks neat and uses a normal style, grammarly might give it a low AI score. In one test, grammarly said a blog post was only 10% AI, but Quetext said it was almost all AI. This means grammarly is not as good for school or hard writing. Other tools like Quetext do better with these kinds of text.

• Grammarly's AI detector often misses:

  • Fancy or tricky AI writing

  • Short blog posts that look professional

  • School or technical writing that looks perfect

You should not use only grammarly to check for AI writing. Special tools can find more hidden AI text. Turnitin is used in many schools and is more accurate in tests. Grammarly helps you write better, but it is not as strong as tools made just for finding AI.

If you need to check important papers for AI, always use more than one tool.

Issues with Older Texts

Grammarly sometimes says old or human writing is AI. Studies show this mistake happens in about 1 out of 100 real papers. People who do not speak English as their first language have more problems. Their writing style can look like AI to the detector. Very formal or well-organized writing can also get flagged, even if it is real.

For example, a paper written before AI tools were made was marked as almost all AI. Formal speeches and technical reports can get the same mistake. These errors can make trouble for students, teachers, and workers. Grammarly and other tools look for patterns, but they do not know what your writing means.

Special tools like Turnitin work better than grammarly for finding AI. Turnitin and Copyleaks have gotten perfect scores in some tests. Grammarly often misses or gets things wrong. But no tool is perfect. You should always check flagged writing yourself and use more than one tool for important work.

Grammarly AI Content Detector Review: Comparison

Grammarly vs. Competitors

Many people compare the grammarly ai content detector to other tools. Turnitin is very popular in schools. It has a big database and strong checking features. Turnitin looks at internet pages, journals, and old papers. It can also find AI writing from many big models. But you need a school account, and it costs more than most tools.

Grammarly gives ai detection as part of its writing tools. You also get grammar checks and plagiarism checks. Grammarly Authorship lets you see how you write and change your work. This helps in school and work. But reviews say grammarly misses about 65% of AI writing. It can also be unfair to people who do not speak English as their first language.

Other tools like ZeroGPT and QuillBot are good in different ways. ZeroGPT says it is very accurate and works in many languages. QuillBot gives quick feedback and can be perfect in some tests. OpenL is free and simple to use, but we do not know how accurate it is.

Here is a quick comparison:

When to Use Grammarly

Grammarly is good for quick checks when you edit. The ai detection gives you one score to help you spot AI writing fast. Many people say it is best to use grammarly first, not last.

For important work, like school papers or books, you need better checking. Tools like Turnitin or Copyleaks give more details and check each sentence.

Grammarly is great if you want easy and all-in-one tools. You get grammar, plagiarism, and ai checks together. Use grammarly for simple checks, drafts, or when you want fast help. For big or serious work, always use grammarly with other tools and check the results yourself.

Tips

Getting Better Results

You can get more accurate results from grammarly’s AI detector by following a few smart strategies. Many users suggest treating AI as a support tool, not a replacement for your own ideas. Start by using AI-generated content as a rough draft. Rewrite it in your own words and add personal stories or examples that only you can provide. This makes your writing sound more human.

Try to mix up your sentence lengths and styles. Use both short and long sentences. Change your tone when needed. Choose words that fit your unique voice, not just what sounds formal or robotic. If you use grammarly’s features like the AI humanizer or Authorship, you can polish your text and show your originality.

Tip: Always have a human editor review your work. Editors can catch awkward phrases or repeated words that AI might miss.

You should also be open about using AI. If you use grammarly or other AI tools, mention it in your work, especially for school or professional projects. This builds trust and shows you value honesty.

Here are some steps to help you get better results:

1. Use AI as a helper, not the main writer.

2. Rewrite and personalize AI drafts.

3. Add your own insights and experiences.

4. Vary your sentence structure and tone.

5. Use grammarly’s features to polish your work.

6. Ask a human editor to review your writing.

7. Be transparent about AI use.

Avoiding Common Pitfalls

You may run into problems if you rely too much on grammarly’s AI detector. Sometimes, small edits can change the results in ways you do not expect. The detector may flag formal or academic writing as AI, even if you wrote it yourself. Overusing industry jargon or repeating phrases can also make your text look like it was written by AI.

To avoid these issues, keep your personal voice in your writing. Add stories or reflections that only you can share. Do not let automated grammar tools remove all your unique quirks. Run your text through more than one AI detector to compare results. Treat the highlights from grammarly’s features as feedback, not a final answer.

• Watch out for these common mistakes:

  • Relying only on one tool for AI detection.

  • Removing all personal touches from your writing.

  • Ignoring the reasons behind grammarly’s suggestions.

  • Not proofreading or fact-checking AI-generated content.

Remember: Use grammarly’s features as a guide, but trust your own judgment. For important work, always double-check with other tools and review your writing yourself.

Most people in 2025 say grammarly is easy to use. It checks grammar well and helps fix mistakes fast. But the AI detector is better as a helper, not the main tool. If you have important writing, think about these things:

Pick the tool that works best for you. Always check your important writing carefully.
