Clean up AI-written text.

Q: What's the difference between Cleanup and Humanize?

Cleanup strips the machine formatting without touching your words. Humanize is a deeper detector-guided rewrite that softens the writing patterns that read AI.

Q: Will Cleanup make AI text undetectable?

No. It removes formatting tells, not the writing patterns a detector weighs.

Cleanup strips the tell-tale machine formatting that AI tools leave behind — long dashes, curly quotes, the ellipsis glyph, invisible paste characters — and normalizes everything to plain text. It's a quick tidy before you publish or hand something in.

It does not rewrite. Cleanup never changes your words, phrasing, or meaning — it only fixes formatting, and it shows you exactly what it changed. It won't make AI writing read human on its own; a full rewrite is a different tool (Humanize, coming soon).

What it does

Formatting fixes — never a rewrite.

Strips machine formatting

Em/en dashes, smart quotes, the ellipsis glyph, decorative bullets, invisible paste artifacts — and the rare glyphs models love (×, →, ½, ≈, curly primes) that people rarely type. Gone.

Never rewrites

Your words and meaning are untouched. It's deterministic normalization, not paraphrasing.

Shows what changed

A simple honest count — how many fixes and the before/after character sizes. The dashboard adds cleaned-file downloads and history.

Before & after

The tells you can't see — until they're gone.

Paste from ChatGPT or Claude and hidden formatting rides along: curly quotes, em-dashes, an ellipsis glyph, non-breaking spaces, zero-width characters. Cleanup normalizes all of it to plain text — same words, no machine fingerprint.

Pasted from a chatbot “The results—as we’ll see—speak for themselves…” ·—curly quotes, em-dashes, ellipsis glyph, a zero-width space

After Cleanup "The results - as we'll see - speak for themselves..." · plain quotes, hyphens, three dots, nothing hidden

FAQ

Common questions.

Does Cleanup change my writing?

No — it's deterministic normalization, not paraphrasing. Every word and its meaning stay exactly as you wrote them. It only fixes formatting characters.

What's the difference between Cleanup and Humanize?

Cleanup strips the machine formatting without touching your words — free, instant. Humanize is a deeper, detector-guided rewrite that softens the writing patterns that read AI. Cleanup is the first, safe step.

Will Cleanup make AI text undetectable?

No, and it doesn't try to. It removes formatting tells, not the writing patterns a detector actually weighs. If your text reads machine-written, the words are what matter — that's what the scanner (and Humanize) work on.

Is it free?

Yes — Cleanup is free with a signed-in account, and it keeps a history of your clean-ups.

Why does AI text have so many em dashes?

Models learned from heavily-edited published writing, where em dashes are common — so they reproduce them at far above typical rates, along with curly quotes and the single-character ellipsis. The cluster of typography together is the paste fingerprint; Cleanup normalizes all of it in one pass.
