Alphabet
In Broca’s area, where speech is made, live 26 tribes, one per letter, sacrificed daily to give you words. The Renegades crossed the walls to stop it.
Alphabet is Rtility’s own NFT collection: 26 tribes of hand-drawn letter characters on Ethereum, and a word game where holders spell words with the letters they own. Claude, Anthropic’s AI model, turns every word into a new chapter of the story.
Pre-launch. The mint contract, art generator and whitelist service are built; the Claude word game is in design. Nothing is live yet.
Where Claude fits
- InA word a holder spells from letters they own, plus the Alphabet canon and style guide.
- ClaudeChecks that the word is real, judges how hard it was to simulate, and writes a short chapter in the voice of the tribes that spelled it.
- OutA new chapter in the public Chronicle, credited to the holder, with those letters marked as saved from the sacrifice.
