The tools give you the arithmetic. For a decision — buying a numeric domain, choosing a business phone number, setting a launch price — book a strategy call.

Every calculation runs in JavaScript on your device. The decoder uses exact big-integer arithmetic, tests primality by trial division up to one trillion, and factors numbers in the same range. Numerology tools use the Pythagorean letter table (A=1 … I=9, J=1 …) and keep master numbers 11, 22 and 33. The memorability score is a transparent heuristic: shorter strings, fewer distinct digits, repeated runs and culturally favoured digits score higher; the digit 4 scores lower because many East Asian buyers avoid it. It is not a valuation.
