AI Text Humanizer

It measures the statistical fingerprints AI text carries: stock vocabulary ('delve', 'moreover', 'a testament to'), unusually uniform sentence lengths, near-zero contractions, heavy em-dash use, and sentences that open with formal transitions. These are the same classes of signal commercial detectors are built on — the difference is this one runs entirely in your browser and shows you exactly which phrases tripped it instead of hiding behind a single number.

Honest answer: no tool can promise that, and any site guaranteeing '100% undetectable' is selling you marketing. What the rewrite does is remove the measurable tells detectors key on, so scores generally drop substantially — the after-score here is recomputed for real, not hardcoded. Worth knowing the flip side too: detectors regularly flag genuine human writing, which is why their results are treated as a signal, never proof.

No — the rewrite is rule-based and meaning-preserving. It swaps stock words for plain ones (utilize → use), adds contractions, replaces em-dashes with commas, splits marathon sentences, and deletes throat-clearing openers like 'In conclusion'. It never adds ideas, facts, or sentences you didn't write. Every changed word is highlighted in the output so a thirty-second read-through catches anything you'd phrase differently.

No. The scoring and the rewriting both run as JavaScript in your browser tab — there's no server call, no account, and nothing stored after you close the page. That makes it safe for unpublished essays, work documents, and client copy, which is exactly the material people are usually most nervous about pasting into online tools.
