Why AI-generated text is detectable

Large language models like ChatGPT, Claude, and Gemini are trained on patterns in human writing, but they consistently over-apply certain conventions. Over time, these statistical habits become recognisable fingerprints.

Em dashes (—)

AI models use em dashes at roughly ten times the rate of typical human writers, often inserting them as parenthetical asides mid-sentence — exactly like this.

Curly / smart quotes

Models trained on formatted text output typographic “curly” quotes and apostrophes. Plain-text pipelines and detectors flag these as non-human formatting.

Invisible characters

Some model outputs embed zero-width spaces (U+200B), soft hyphens, or BOM characters that are invisible but detectable by tools scanning raw Unicode.

Sycophantic openers

Phrases like “Certainly!”, “Absolutely!”, and “Great question!” are near-universal in AI responses and immediately signal machine-generated text.

Filler buzzwords

Words like “leverage”, “delve”, “seamless”, and “notably” appear in AI output at statistically anomalous rates compared to human prose.

Template placeholders

AI-drafted documents often leave {First Name} or [Company] tokens unfilled. Cleaning tools can surface these so nothing slips through to the final copy.

Students & academics

Remove typographic anomalies from AI-assisted drafts before submission to reduce the chance of triggering AI-detection software.

Frequently asked questions

What are AI writing markers?
AI writing markers are characters and phrases that appear disproportionately often in AI-generated text. Common examples include em dashes (—), curly quotes (“”), ellipsis characters (…), filler openers like “Certainly,” and “Great question!”, and buzzwords like “leverage”, “delve”, and “notably”. These patterns can make writing feel mechanical or flag it as AI-generated to readers and detectors.
Why do AI models use so many em dashes?
Em dashes appear frequently in the high-quality writing that language models are trained on — academic papers, long-form journalism, edited books. Models learn to replicate this style and apply it far more liberally than a human editor would, making the em dash one of the strongest statistical signals of AI-generated text.
What are zero-width and invisible characters?
Zero-width characters are Unicode code points that have no visible glyph — they take up no space on screen. Examples include the zero-width space (U+200B), zero-width non-joiner (U+200C), and the byte order mark (U+FEFF). Some AI outputs include these characters, which can interfere with text processing, word counts, and AI-detection tools even though they are completely invisible to readers.
Will this help me pass AI detectors?
Removing typographic markers reduces some signals that detectors look for, but it is not a guarantee. AI detectors analyse many factors including sentence structure, vocabulary distribution, and perplexity. This tool addresses the surface-level character and phrase patterns — think of it as a first pass before you review and rewrite for voice and style.
Does this tool change my meaning?
No. The fixes are purely cosmetic: em dashes are replaced with commas or hyphens, curly quotes become straight quotes, ellipsis characters become three dots, and so on. Buzzwords are flagged for your attention but never auto-removed — you decide whether to rephrase them.
Does this work with ChatGPT, Claude, Gemini, and other AI models?
Yes. The tool cleans raw text regardless of which model produced it. Paste output from ChatGPT, Claude, Gemini, Copilot, or any other AI writing assistant and the same rules apply.
Does my text leave my browser?
Never. All processing runs locally in your browser using JavaScript. Your text is never sent to a server, stored, or logged. This makes the tool safe to use with confidential drafts, client documents, and sensitive business content.
Is this free?
Yes, completely free. No account, no sign-up, no usage limits.
What kind of text should I paste?
Any text you have drafted or refined with AI assistance — emails, blog posts, reports, essays, social media captions, product descriptions. Paste the full text, toggle which fixes to apply, and copy the cleaned output.
Is this site Vibe coded?
Yes this website is vide coded, everyhing but this card right here was made by Claude Code. Iroic right?
