The demo is a scaled-down desktop window, so it's small on a phone. Turn your phone sideways, or use a computer.
The only staged parts here are the verdict and the pitch curve: judging your pronunciation needs the model on your computer, so the results are pre-set to match the real app.

Does it need the internet? Do my sentences get uploaded?
Look-ups, speaking practice and your word list are all offline. Only AI chat goes online, and it needs your own key. Phone sync is off by default; when on, it syncs only your saved words, their sentences and your progress, and one button wipes it all, cloud copy included.
Which systems does it run on?
Windows and macOS (Apple silicon) are available now; Linux comes next (double-Ctrl capture doesn't work under Wayland).
How much does it download the first time?
About 460 MB (speech scoring, speech synthesis, dictionaries), downloaded on first launch, then everything is offline. The transcription model is about 130 MB and only downloads when you use it.
How is this different from Yomitan + Anki?
They've perfected “look up + remember”; manabiu does the second half: pushing what you remember until you can say it.
Can I use it on my phone?
There's a phone web app for reviews that works offline. Speaking practice is on the computer — scoring runs a local model.
Why doesn't it mark pitch right or wrong?
A verdict we can't make reliably is worse than none. For now it shows the high/low of each beat as a reference.
