Kaiwaflow is a personal AI tutor for conversational fluency. Built around one principle: flow first, perfection later. It already knows the people in your life, the places you've been, and the grammar you've been chewing on — because it reads your own learning notes from Drive.
If you're already past the basics — already fluent in another language or two, already comfortable with how learning works — the textbook lesson plan is the wrong shape. You don't need streaks, leaderboards, or another quiz on past-tense conjugation.
You need a partner who'll meet you mid-conversation, model the natural form when you stumble, and know who Mac is the next time you mention him. A partner who speaks the dialect you are working on — the slang from your last trip, the grammar from your most recent log entry.
That's the only thing Kaiwaflow tries to be.
Hold space, speak, release. Sensei replies in your ears, not just your eyes. Optional fullscreen mode for hands-free practice with subtitles you can toggle off. High Fidelity Voice available with Pro.
browser STT primary · Whisper fallbackPoint Kaiwaflow at your Google Drive learning notes — sheets, docs, prose, whatever — and it extracts context and vocabulary in one pass. Sensei knows about the Hokkaido trip, the dog you lost, the grammar from last Tuesday's log entry.
soft cap 20 docs · LLM-driven extractionSensei never interrupts to correct. Instead, she models the natural form back in her reply. For the curious, a small chip below each message lets you see exactly what was tacitly fixed.
a different kind of language appPoint Kaiwaflow at the docs and sheets where your Japanese learning notes already live. Sign in with Google once.
An AI extraction pass pulls vocab + context from every doc. Skim, correct, skip what isn't vocab — same UI handles structured sheets and freeform prose.
Sensei opens with a greeting that mentions someone or somewhere from your notes. Speak or type — whichever fits the moment.
Save anything Sensei says as an Anki card. Your library lives alongside the chat, browsable and exportable. One card at a time.
Pro is one flat $15 per month. No usage meters, no overage fees, no per-message charges. You always know what you'll pay.
We cap High Fidelity Voice at ~3,000 generations per month so a handful of power users don't break the math for everyone. Hit the cap and your browser's built-in voice takes over — Sensei keeps talking, just at lower fidelity until the cap resets on the first of the month.
