Yojowa, LLC is a technology company in Sammamish, Washington. We ship small, focused software: a companion that talks to you while you drive, a stock model that publishes its own misses, a vocabulary trainer that knows when you are about to forget a word, and a tool that reads century-old handwriting from a photograph. Four products, all live, each on the web and in the app stores, and a game: Blockability 3d, our 3D block puzzle.
Your driving companion
A voice-first AI companion for the drive: live traffic, honest arrival times and the best places to stop on the way. Ask what is slowing the road ahead, when you will really get there, or where to stop for coffee, and hear the answer without looking at the screen. Withby talks, so your eyes stay on the road.
AI stock predictions, tracked
AI insight scores and two-week price predictions for thousands of stocks, with the hit rate published in the open, misses included. See the whole market at a glance on the live map, compare sectors and rankings, and follow the stocks you care about on a watchlist. Every prediction is graded when its window closes, so you judge the model by its record, not its promises.
Smart Chinese vocabulary
Master Chinese vocabulary with spaced repetition, interactive flashcards and a study path that adapts to you, from beginner to advanced. LexiTrail shows each word right before you would forget it, so review time goes to the words you actually need. Practise and test by HSK level and topic, and watch your progress day by day.
Read old handwriting
FamilyLore reads the handwriting your family left behind. Scan a page of an old letter, diary or record, and it reads the page line by line in its own language, then translates it into English. Every word is linked back to the handwriting, so you can check and correct it. Russian, Ukrainian, German Kurrent and Sütterlin, Yiddish and more.
A 3D block puzzle
Look down into a well twelve layers deep, turn each falling piece three ways and fill whole layers to clear them. Our puzzle game from 2012, rebuilt from the ground up: free to play with no ads, touch, keyboard and gamepad controls, colour-blind palettes, and it plays offline. Descent, its story mode, is one optional purchase after a free first level. Play it in the browser, on iPhone and iPad, Android or Windows, in 19 languages.
Yojowa is deliberately small. We build narrow products, put them in front of real users early, and keep the ones that earn their place. Most of our engineering, testing and operations run through a fleet of autonomous software agents, which is how a company this size ships and maintains four live products at once.
We publish what we measure, including when the numbers are unflattering. StockMap's public accuracy ledger includes every miss, by design. It is the same principle everywhere else: a claim we cannot check is a claim we do not make.
