How SpellClimb works

Each word carries a predicted difficulty built from grapheme structure, sound, morphology, root pattern and lexical load. That prediction is labelled predicted (unfitted) until responses prove it. Your answers update your ability estimate instantly and, in a nightly batch, can move a word’s published band — only with enough evidence, past a clear margin. No accounts: you are an anonymous device token, deletable at any time via the API.
