AI can’t read this… allegedly
SoulsOnly.tff – A font for humans not AI and keyboard firmware to type in it
This ‘humans-only’ font has commenters cheering, roasting, and side-eyeing the irony
TLDR: SoulsOnly is a font that makes text look normal to people but scrambled to bots unless the special font is used. Commenters loved the anti-AI statement, but the biggest reaction was laughing at the irony that an AI may have helped build it.
A developer dropped SoulsOnly.ttf, a wild little project that turns normal-looking text into machine-confusing nonsense underneath. To human eyes, it reads fine once the special font is applied. To copy-paste tools, scrapers, and bots, it looks like gibberish. It’s less “perfect lock” and more art project with attitude: a statement against the internet’s rush to make everything easy for artificial intelligence to gobble up.
And honestly? The comments are where this story gets juicy. One camp was instantly charmed, calling it a “lovely” conceptual stunt and applauding the rebellious energy of making something “for human eyes only.” Another camp immediately put on the skeptic hat: cool idea, sure, but won’t an AI just figure it out eventually? That tension — clever protest or speed bump at best — became the thread’s main event.
Then came the comedy. Several users pointed out the delicious irony that this anti-AI project appears to have been made with help from Claude, an AI assistant. That sparked the biggest laugh in the room, with commenters basically saying: so the anti-AI font got an AI co-author? Others compared it to old-school anti-scraping tricks from finance sites that swapped numbers around to confuse crawlers, which gave the whole thing a nostalgic “the web is healing, badly” vibe. Bottom line: people aren’t treating SoulsOnly like an unbreakable shield — they’re treating it like a cheeky, stylish act of resistance, with a side of meme fuel.
Key Points
- •SoulsOnly stores text as randomized four-byte ASCII noise per visible character and relies on font rendering to display readable words.
- •The project uses font mechanisms including cmap and GSUB ligatures to convert encoded ASCII carriers into opaque half-glyphs that combine into final characters.
- •Applying the font to ordinary plaintext does not decode readable text; only the intended cipher stream renders correctly.
- •The project ships as static TTF and OTF fonts and as a variable TTF font with a custom REVL axis that controls an illegible-to-legible-to-illegible reveal sequence.
- •SoulsOnly supports the full US-QWERTY printable set, with editing behavior adapted so deletion and cursor movement operate in four-byte units.
