About HumanType
HumanType was born from a simple observation: AI-generated text carries invisible typographic fingerprints that make it detectable. Em dashes, curly quotes, and Unicode ellipses are all tells — subtle signals that a machine, not a human, wrote the text.
Our mission is to give writers control over how their text is perceived by AI detection tools. By normalizing typographic symbols to plain ASCII equivalents, HumanType removes one of the clearest signals that AI detectors rely on — all while preserving the meaning and readability of your content.
Open-source and transparent. HumanType is MIT-licensed and fully open-source. The entire codebase is available on GitHub. We believe that tools for AI text humanization should be transparent, auditable, and free from hidden agendas.
Privacy-first. HumanType runs entirely in your browser. No text is ever sent to a server. No analytics. No tracking. No data collection. What you paste stays on your device.
Built with care. HumanType is maintained by a small team of developers and writers who believe that technology should empower, not expose. We're committed to keeping this tool free, fast, and effective.
What We Do
HumanType is a typographic normalization tool that replaces Unicode characters commonly produced by AI language models with their plain ASCII equivalents. We handle em dashes, curly quotes, ellipsis glyphs, non-breaking spaces, special fractions, legal symbols, and directional arrows — 19 replacement rules across 7 categories.
Why It Matters
AI detectors analyze more than just word choice — they inspect the actual Unicode code points present in text. Em dashes (U+2014), curly quotes (U+201C/201D), and Unicode ellipses (U+2026) are statistically associated with machine-generated content because most humans type hyphens, straight quotes, and three dots.
