Why is my writing flagged as AI?

Your writing can receive a high AI score even if you wrote it yourself. AI detectors look for patterns in text. They do not watch you write, so a flag cannot prove how your work was made.

If you are checking a draft, start by reading what the result actually says. “This resembles AI writing to this model” is a different claim from knowing who wrote it.

Why a flag can happen

Human and AI writing can share patterns. Polished or formal writing is not automatically AI writing. A detector may find a pattern it associates with AI, but it cannot establish the cause from the text alone.

Short passages also offer less context. Nota requires at least 50 words, and its published human-text test information does not cover passages under 250 words. Between those limits, you can receive a result without a measured false-positive rate for that length.

The text sent to the checker matters, too. A PDF with broken extraction, a passage full of quoted material, or a large reference list may differ from the prose you meant to check. Review the input and the result’s coverage note.

Read the number carefully

An AI-likeness score is not a percentage of words written by AI. A score of 80, for example, does not mean “80% of this essay was generated.” It describes how the checked text reads to that model.

A false-positive rate describes errors on a particular set of human writing in a test. It is not the chance that your own result is wrong. The test sample and the model version matter; results on one sample do not promise the same performance on every writer or subject.

What to do next

1. Review your actual text. Make sure the checker received the passage you intended, with enough words and without extraction errors.
2. Read the explanation and limits. Note whether the result is uncertain and whether only part of a long document was checked.
3. Keep your drafts and sources. Outlines, notes, references and available document history can help you explain your process.
4. Follow the rules for the assignment or publication. If you used AI assistance, describe it as required. A low detector score does not replace those requirements.

If someone questions your work, ask which passages concern them and explain your process using the material you have. A detector score is one piece of context, and sometimes an unreliable one.

Should I keep editing until the score goes down?

Edit when it improves your argument, clarity or use of sources. Repeatedly changing wording to lower a detector score gives you no guarantee about another checker or a later result.

Nota does not promise to make writing pass another detector. It helps you check a draft and understand its result. A high score does not establish misconduct, and a low score does not certify human authorship.

Can a writing history report help?

It may add context. Nota can summarize available document information in a separate writing history report. Browser-supplied history is not independently verified, and uploaded document metadata has limits. A signed report protects the report from unnoticed changes; it does not prove that its source history is authentic or complete.
