RabbitLex
Train Like a
Champion Plays.
Four drill modes, nine AI insights per word, and 280,887 tournament words that don't care how confident you feel.
Most word tools are built for people who want to feel smart. RabbitLex is built for people who want to become better. There is a difference, and it shows on the board.
We started with the hardest audience we could find: tournament players who memorise 280,887 words, drill hooks until they are reflex, and lose matches by a single tile they did not quite trust. That audience cannot be flattered into confidence. Facts, depth, and precision — nothing less earns their attention.
A tool that satisfies the most demanding players in the world is a tool that can satisfy anyone who takes language seriously.
We built every training mode around the real structure of competitive play. Valid or invalid — fast, no hints. Hook chains, score calculation, seven-letter racks under a countdown. No gamification layer over shallow mechanics. The drill is the product.
The name says what we believe. A rabbit follows a thread deeper than most would go — not because it must, but because the thread keeps leading somewhere interesting. Curiosity that runs to its conclusion becomes mastery. That is the only training philosophy we have.
Every word. One permanent coaching profile.
One AI call per word, stored forever. Every player gets the same instant coaching — no repeated compute, no hallucinated dictionary definitions. Nine fields: mnemonic, strategy, etymology, pattern, danger traps, hook memory, Scrabble context, related words, and the story behind the word. Generated once by a tournament-specialist AI. Cached permanently.
