Synonym swaps do not
Detectors read structure and rhythm. Turnitin says it flags AI text even after AI paraphrasing, and swaps leave that structure in place.

How AI detectors
decide.
Detectors do not know who wrote a text. They estimate how likely its patterns are to come from a model, and they all make mistakes in both directions.
They score sentences
Turnitin scores each sentence and reports the share above its threshold. It shows no number for scores between 1% and 19% because false positives are more common there.
They misread real writers
A 2023 study in Patterns found seven detectors flagged non-native English essays as AI 61% of the time on average.
They look for humanizers
Turnitin added detection of AI bypasser tools in English in August 2025; GPTZero reports detecting some bypassing tools too.
How to avoid AI detection in your writing
Three steps that change what detectors measure.
Rewrite the structure
Use Balanced mode to rework phrasing and rhythm across the whole text, not just single words.
Add what only you know
Specific examples, checked numbers and your own opinions change a text in ways a model would not.
Check & keep your drafts
Run the AI Detector, and keep outlines and drafts in case you ever need to show your process.
What lowers an AI score, and what does not
Based on what detector makers publish and what we measured.
Reworking how it is written does
In our test, one Balanced rewrite moved 60 of 60 AI-written texts to a human-written verdict on ZeroGPT.
Your own substance matters most
Writing that carries your examples and reasoning reads as yours, to detectors and to the people who read your work.
Rewrite and check

The humanizer and the AI Detector side by side, with every setting visible.
Three rewrite strengths
Choose a light polish or a deeper rewrite. Aggressive is intended for English drafts.
A tone that fits
Set the voice for your reader, from a careful academic register to a friendly message.
Made for your kind of writing
Choose the purpose of your text to give the revision a clearer direction.
Write across languages
Choose your output language. Light and Balanced support multilingual drafts.
Keep your important words
Add names, technical terms, or phrases you want the rewrite to preserve.
Quotes & formatting controls
Guide how quotes and formatting are handled, then review the finished result.
Bring your own document
Paste a draft or import a supported file. Check the extracted text before you start.
Review, edit & export
Keep the source and revision side by side. Make your final edits, then take your text with you.
Pick up where you left off
Signed-in history keeps requests and results together so you can revisit an earlier draft.
Open your historyWhat raises and lowers AI detection
Signals from detector documentation and our own test.
| Writing feature | Effect on detection | Source |
|---|---|---|
| Uniform sentences and stock phrases | Raises the AI score. | Detector documentation |
| Light paraphrasing or word spinning | Often still detected. | Turnitin and GPTZero |
| Short texts | Less reliable results either way. | Turnitin needs 300+ words; GPTZero says accuracy rises with length |
| A full Balanced rewrite | 60 of 60 read as human on ZeroGPT. | Our October 2026 test |

Falsely flagged work.
Detectors can flag genuine writing. Keep drafts, and rewrite AI-assisted parts where allowed.

20,000 words during the three-day trial. It renews as Pro with a fresh 20,000-word monthly allowance after the first monthly charge; unused trial words expire. This paid trial converts to monthly billing even when yearly plans are selected. Cancel before the next billing time shown in checkout and your receipt to prevent renewal.

Try free toolsBilling & usage details
Each processing pass may use words. Humanizing and source matching use the ordinary word allowance; AI detection uses half the input count rounded up. Other workflows have their own usage rules in your account. Beyond the 500-word free trial of the humanizer and AI detector, AI processing requires sign-in and an available allowance; free tools do not include a paid humanizer plan.
Annual plans are charged in one yearly payment; the monthly equivalent is for comparison. Included words reset monthly and do not roll over. “Unlimited” is a plan name with a 100,000-word monthly allowance. Buying an allowance does not guarantee a detector score.
Cancel in your account before the next billing time to stop renewal. Cancellation does not refund an earlier charge; refund requests follow the refund policy. Checkout shows your final total, applicable tax and renewal date.
A few things worth knowing
Avoid AI Detection FAQ
How detectors work, why they make mistakes, and what to do about it.
Can AI detectors be wrong?
Yes. Turnitin says its score should not be the sole basis for action and that false positives are more common below 20%. A 2023 study found detectors flagged non-native English essays as AI 61% of the time on average.
Read: how to read Turnitin and GPTZero reports
Does paraphrasing avoid AI detection?
Not reliably. Turnitin says it detects AI-paraphrased text and, since August 2025, text modified by AI bypasser tools in English. Light rewording leaves the structure detectors read.
What worked in our test?
One Balanced rewrite moved 60 of 60 AI-written texts to a human-written verdict on ZeroGPT, with the average AI score falling from 89% to 12%. We have not measured other detectors.
Read the ZeroGPT test
How do I avoid being falsely flagged?
Write in your own voice, keep outlines and drafts, and use version history. If a score is challenged, your process is the strongest evidence.
Which detector does the built-in checker use?
It sends your text to ZeroGPT’s detection API and shows the score and verdict ZeroGPT returns.
Is it allowed to avoid AI detection?
Follow your institution’s or employer’s rules. Where AI assistance is allowed, disclose it when required; never use a rewrite to misrepresent who did the work.

Is it free to try?
Yes, up to 500 words with no account, including the AI Detector.
