Vaak Turns Everyday Words into a Private Cipher

Field notes

Vaak describes Anka Lipi as a substitution cipher where letters become numbers, then wraps practice around two response modes: typing a decoding or selecting it from close alternatives. Its progression starts with short phrases and adds longer, trickier ones, while the stated tracking covers pass/fail results, accuracy, and streaks. The page also says some challenges use the learner's name and that the service avoids ads and trackers.
