Name Analyzer
Score words, names and brand candidates across multiple dimensions. Today: typability — how ergonomic a name is to type, based on a Carpalx-inspired effort model. Coming soon: pronunciability, sonority and memorability.
How the score works
The total effort for a word is calculated as:
effort = Σ(row_cost + finger_cost) + 3·SFBs − 0.5·hand_alternations
- Row cost: home = 0, upper = 1, lower = 1.5.
- Finger cost: index = 0, middle = 0.5, ring = 1, pinky = 2.
- SFB (same-finger bigram) — two consecutive letters pressed by the same finger. Hurts flow severely; penalty
+3. - Hand alternation — consecutive letters on opposite hands. Bonus
−0.5.
Lower score = easier to type. A perfect 3-letter word scores around 0.5; a mediocre 4-letter word lands around 4. A word with even one SFB jumps up by 3 just from that penalty alone.
This is a simplified client-side model — the real Carpalx paper includes triad (3-letter) penalties, lateral stretch bigrams, and path-length integration. For detailed academic-grade analysis use the Carpalx paper or the Keyboard Layout Analyzer.
