01 PRODUCTS Products
Phrasy
AI English conversation
Designed so you can actually say it.
Not an app for reciting phrases. Each day's phrase is a foothold for solving a different conversation problem. Goal-driven role-play with AI, so that your own words come out even in a first conversation.
Moshimon
もしもんCall logging app
Turn phone work into a game.
Calls, conversations, appointments. Every time you log the day's numbers you earn experience points and the stage advances. A logging app that turns a job chased by targets into a game where progress is visible.
Berserker
Strength training and running app
AI decides. You finish.
The menu your AI coach builds becomes the set sheet, the rest timer and the run-walk voice guide, as it is. No time spent wondering, only moving. When you're done, only what you actually did remains.
tsumini
Block-stacking game
Just stack. Somehow you can't stop.
A block-stacking game that runs right in the browser. Nothing to install. Add it to your home screen and it plays like an app.
Mermaid Viewer
Developer tool
Write it, and it's a diagram.
A viewer that draws the diagram the moment you write Mermaid code. No build step, and it works offline.
The world is more interesting than you think.
Beyond every language you don't know lies a world you don't know. A language is a world.
That's why we want to build language learning that truly helps. Not for a score, not for a streak, but for the experience of a world that genuinely opens up.
A dull job, a few spare minutes: look at them differently and they become more interesting. Craftbase builds products for exactly that.
P.S.We also take on contract development.
Web and mobile apps, from design to implementation. A small team working fast, the same way we build our own products. Tell us about your project in the form below.
