Strip the giveaway tells from ChatGPT, Claude, Gemini and other LLM output: em-dashes, smart quotes, opener phrases like "Certainly!" or "Here's…", header overuse, emoji clutter and overly-bulleted lists. Paste, clean, copy — your AI-generated text sounds human in one click. Free, runs in your browser.
Large language models like ChatGPT, Claude and Gemini have unmistakable stylistic fingerprints. They love em-dashes, smart quotes, opener phrases like "Certainly!" or "Here's a…", excessive bullet points, header-heavy formatting and just enough emojis to give it away. These tells are fine for chat, but they make AI-generated content easy to spot when you publish it as a blog post, email, social caption or LinkedIn update — and they trigger most "AI detectors" instantly.
This cleaner runs a series of pattern-based rewrite rules entirely in your browser. Paste in your AI output, choose a preset (Light, Moderate or Aggressive), and the cleaned version appears on the right side. Toggle individual rules to fine-tune the result. Nothing leaves your device — your text is never uploaded.
Step 1 — Paste your AI text. Drop the raw output from ChatGPT, Claude, Gemini, Copilot or any LLM into the left textarea. The cleaned version updates live on the right as you type.
Step 2 — Pick a preset. Light keeps the meaning intact and only strips obvious typographic tells (em-dashes, smart quotes). Moderate also removes opener phrases and transition-word overuse. Aggressive applies everything, including emoji removal and bullet-list flattening.
Step 3 — Fine-tune. Toggle individual rules under the preset to keep the behavior you want. The count next to each rule shows how many times that pattern was found in your text.
Step 4 — Copy or download. Use the "Copy cleaned text" button to paste into your blog, email or CMS. Use "Download .txt" if you prefer a file.
This tool is a starting point, not a magic eraser. A genuinely human-sounding piece needs editing for argument structure, anecdotes and voice — things no regex can fix. But for the vast majority of "this clearly came out of ChatGPT" giveaways, surface-level cleanup gets you 80% of the way to publishable in seconds. Use it for marketing copy, social media posts, drafts you'll polish further, internal docs, anywhere the AI tells are distracting but the content is fine.
Avoid using it for academic submissions or anywhere honesty about AI assistance matters — disguising AI authorship can violate publication or institutional policies. Cleaner output ≠ undetectable; modern AI detectors look at much more than surface tells.
Before: "It's the best approach — by far — for this use case."

After: This approach scales well. …ChatGPT and Claude use em-dashes (—) several times more often than the average human writer. Most people on a regular keyboard type a single hyphen (-) or no dash at all. A paragraph with two or three em-dashes is one of the strongest visual indicators that a text was generated.
Sometimes, sometimes not. Surface cleanup is one signal; AI detectors also look at perplexity, burstiness, sentence rhythm and vocabulary patterns. Cleaning removes the most obvious typographic tells but does not rewrite sentence structure. For undetectability you need to rewrite, paraphrase and add personal voice — which only you can do.
Yes. The patterns covered are common to every major LLM — they all share similar pretraining data and reinforcement-learning behaviors. You'll get the same cleanup quality on output from ChatGPT, Claude, Gemini, Llama, Mistral, Copilot or any local model.
Light: only typographic fixes (em-dashes, smart quotes, invisible whitespace). Safe for any text. Moderate: adds opener-phrase and transition-word cleanup. Good default for marketing copy. Aggressive: also removes emojis, flattens short bullet lists, and strips AI buzzwords (Unleash, Boost, Dive in, etc.). Use when you want maximum "human voice".
The cleaner is regex-based and only modifies text around recognized patterns. Code blocks, URLs, technical terms and proper nouns are left alone. However, if you're cleaning a markdown document with code blocks, double-check the output before publishing — automated cleanup can occasionally affect things you didn't intend.
No. Everything runs entirely in your browser using JavaScript. The cleaning rules execute locally. No text is sent to any server, no signup is required, and no copy of your content is stored anywhere except in your local browser tab.
Yes. Your preset selection and any individual rule toggles are remembered in your browser's local storage. When you return to the tool, your last configuration is restored automatically.
For personal writing, marketing copy, drafts and brainstorming — yes, this is just a formatting helper. For academic submissions, journalism, or any context where AI disclosure is required, cleaning surface tells without disclosing AI assistance is a separate issue. Use the tool to improve readability, not to deceive contexts where honesty matters.
