I wrote this myself, but it sounds like AI. What am I doing that reads that way?
Usually it's habits, not you: stock transitions, safe word choices, sentences of the same length and an ending that repeats the opening. Paste a paragraph into HidenGPT's free cliché checker to see which phrases and rhythm patterns it marks, then fix them in your own words. It's an editing check, not an AI detector.

How to do it in HidenGPT
- 01
Paste one paragraph into the free AI cliché checker and note each phrase and pattern it flags.
- 02
Rewrite each flagged phrase the way you'd say it out loud, and swap one general claim for a detail only you know.
- 03
Break up any run of same-length sentences: split a long one, or join two short ones.
- 04
If you only want typos and grammar fixed, paste the text into Rewrite and pick Fix spelling & grammar; it leaves your style, word choice and sentence structure alone.
- 05
Keep your drafts and version history, so you can show how the piece came together if anyone asks.
Rewrite & Edit: Humanize, shorten, simplify or proofread your own draft.
Why human writing can read as generated
Readers and detectors react to the same thing: predictable text. School teaches a fixed structure, stock transitions such as “Furthermore” and “In conclusion”, and topic sentences that restate the prompt. Careful writers in a second language often pick the safest common word. All of that makes writing predictable, and predictable is what generated text looks like.
Research backs this up. In a 2023 Stanford study published in Patterns, seven AI detectors flagged an average of 61% of 91 TOEFL essays by non-native English speakers as AI-generated, while scoring essays by US eighth graders almost perfectly. The essays all seven flagged used more predictable word choices. Turnitin says its own AI writing score can misidentify human writing and shouldn't be the sole basis for action against a student.
What the checker does and doesn't do
The free AI cliché checker runs the same analysis as HidenGPT's red pen, in your browser. It marks about 80 stock phrases in English and Turkish, flat rhythm, very long sentences, em-dash pile-ups and repeated sentence openers, and gives a 0-100 naturalness score. It takes up to 20,000 characters, and nothing you paste is sent or saved.
The score is an editing score: 85 and up reads as written by a person, 65-84 as mostly natural. It can't tell who wrote a text, and it says nothing about what an AI detector will report. Use it to find the sentences worth rewriting, then rewrite them yourself.
What to keep, and what to change
Not every flag needs fixing. A transition you'd actually say out loud is fine; three in a row is the problem. Keep your own words, even plain ones, and your own examples. A plain sentence with a real detail reads more like a person than a polished one with nothing in it.
The changes that help most are small. Cut the sentence that announces what the paragraph will say. Replace “many people” or “various factors” with who and what. End on your strongest point instead of a summary, and put one short sentence after a long one. Then read the paragraph aloud, and anything you wouldn't say to a classmate, say the way you would.
Not the right tool if
- Making AI-written text pass as your own. HidenGPT isn't built for that, makes no promises about any detector, and your school's rules on AI apply.
- Settling an accusation. If a detector has already flagged your work, your drafts and version history matter more than any edit; see the page on what to do when that happens.
- Polishing a finished essay written in your second language. The page on polishing an ESL essay covers that.
Other ways to do it
- Reading it aloud, or having a friend read it to you
- Free, and the fastest way to hear which sentences sound like nobody talking.
- Your school's writing center
- Feedback from a person on writing you did yourself, and the safe choice when AI tools aren't allowed.
- Grammarly or a spell checker
- Typos and grammar in your own text. Check that any rewording it suggests still sounds like you before you accept it.
Questions
Why does my writing sound like AI?
Usually because parts of it are predictable: stock transitions, safe word choices, sentences of the same length and a conclusion that repeats the introduction. Specific details and varied rhythm read as a person.
My natural writing sounds like AI. Is something wrong with it?
No. Clear, formal, carefully structured writing is what school teaches, and it overlaps with how generated text reads. Keep the structure and add what only you know: your examples, your opinion, the words you'd use out loud.
Why do AI detectors flag writing by non-native speakers?
Because they score how predictable the wording is, and writers in a second language often choose common words. In a 2023 Stanford study, seven detectors flagged an average of 61% of TOEFL essays by non-native speakers as AI-generated.
Is the cliché checker an AI detector?
No. It marks writing habits that read as generated and gives a 0-100 editing score; it can't tell who wrote a text and says nothing about what any detector will report.
Will fixing these habits stop a detector flagging me?
Nobody can promise that, and HidenGPT makes no promises about any detector. Detectors are unreliable in both directions; fix the habits because the writing reads better, and keep your drafts as a record of how you worked.
Can HidenGPT fix my grammar without changing my style?
Yes. In Rewrite, Fix spelling & grammar corrects only spelling, punctuation and grammar and skips the red pen, so your word choice and sentence structure stay as you wrote them.
Is the checker free?
Yes. It needs no account, has no daily limit and runs in your browser, so nothing you paste is sent or stored.
