Why we built the most reliable AI humanizer on the market.
AI writing tools like ChatGPT and Claude are incredibly powerful, but they all share one problem: they write like robots. Every sentence follows the same predictable patterns, every transition is formulaic, and every paragraph sounds exactly the same.
That's where NoteCleaner comes in.
NoteCleaner uses a combination of rule-based rewriting and advanced AI to break the patterns that AI detectors look for. We vary sentence length aggressively, add natural contractions, replace generic AI phrasing with everyday vocabulary, break passive voice, and inject subtle rhythm beats that only human writers use.
Unlike other AI humanizers, we never store your text, never train on your data, and never share anything with third parties. In Local mode, all rewriting happens in your browser - your text never leaves your device. Even in AI mode, text is sent directly to our API endpoint without logging or storage.
Whether you're a student who needs to turn in an essay, a professional drafting an email, or a content creator publishing online, NoteCleaner helps you use AI as a tool without being penalized for it. We believe AI should assist your writing, not replace your voice.
Every feature is designed to lower scores on Turnitin, GPTZero, Originality.ai, and ZeroGPT.
We never alter facts, numbers, citations, or your core message. Only the writing style changes.
Local mode rewrites happen in milliseconds. AI mode processes chunks in seconds.

Everything you need to know about NoteCleaner.
Yes. NoteCleaner uses a combination of aggressive sentence length variation, contraction injection, synonym replacement, filler word stripping, and passive voice conversion to significantly lower AI detection scores. Most users see detection rates drop from 90%+ to under 30% after a single pass. Deep mode can get scores even lower. Results vary by input text, but we consistently outperform other tools on the market.
No, never. In Local mode, all rewriting happens 100% in your browser - your text never leaves your device. In AI mode, we send your text to our Cloudflare Worker endpoint for processing, but we don't store logs, don't save inputs, and never use your text for training or any other purpose. Privacy is our #1 feature, and we've built the entire product with that principle in mind.
English works best for both Local and AI modes. Spanish, French, German, and other European languages work well in AI mode. Chinese, Japanese, and Korean support is experimental in AI mode and currently unavailable in Local mode. We're actively working on better multilingual support - join our newsletter to get updates.
No. NoteCleaner is specifically tuned to preserve every fact, number, name, quote, and citation exactly as it appeared in your source text. The rewrite only affects phrasing, sentence structure, and writing tone - never your actual content. We recommend always double-checking output for high-stakes work, but our design principle is "first, do no harm."
No account is required for the Free tier. You can start using NoteCleaner immediately without signing up or providing any personal information. Pro and Ultra tiers require an account for subscription management and word quota tracking, but you can try everything in Free mode first before deciding to upgrade.
You can upload .txt plain text files, .md Markdown files, and .pdf documents. PDFs are parsed client-side in your browser using PDF.js. Images and scanned PDFs (which contain images of text rather than actual text) are not supported. The word limit is approximately 10,000 words per run for Free tier.
NoteCleaner is built specifically for structured text like essays, notes, reports, and academic writing - not generic content spinning. We preserve your headings, bullet points, citations, and document structure instead of flattening everything into a single uniform paragraph. We also don't mark up prices 10x for "school mode" or similar gimmicks. NoteCleaner is transparent, fairly priced, and built by people who actually use the product themselves.
Local mode uses our rule-based rewriting engine that runs entirely in your browser. It's fast, free, private, and works offline. AI mode uses DeepSeek's advanced language model for more natural, context-aware rewriting. AI mode produces better results for complex text and is required for Deep strength level. Both modes produce output that significantly lowers AI detection scores.
