Why Kotone
Mid-teamfight, your teammate pings you to call out. That's the moment.
AFTER
After
Hold a hotkey, say “jungler bot side”. Release, and the words are already sent. Your fingers never left the keyboard.
✅ Received, sent ✨
Kotone is communication that never interrupts — input inside the flow of the game, not outside of it.
Features
Every tool on the streaming desk, sharpened
Six pieces, all crafted around one rule: keep your hands on the keyboard.
Streaming transcription
Default X-ASR bilingual model with punctuation, words appear as you speak; VAD voice-activity detection ships in the app and is ready at launch.
Global hotkeys
Hold-to-talk or tap-to-toggle, bind any key; press again while the hint is showing to start the next line instantly.
Gaming glossary
100 League of Legends terms built in; new entries merge on update, your customizations and deletions never get lost.
Esports overlay
Card or capsule styles, fully draggable with saved position, click-through to the game; streaming engines render text live.
History & replay
Every recognized line can replay its original audio with a waveform; empty transcriptions never send and leave no trace.
Local-first privacy
All models run on your machine, nothing is uploaded; tray resident, auto-update, and one-click admin restart.
Interaction modes
Four modes for every kind of teamfight
From hold-to-talk to one-shot to never-stopping — one of these is your rhythm.
Walkie-talkie
Hold to talk, release to send.
As direct as a radio: hold the hotkey, speak, release — it sends. No hesitation.
Voice recorder
Tap to start, tap to stop.
Tap to start recording, tap again when you're done — the whole take sends in one piece.
One-shot
Auto-stops and auto-sends when you're done.
A natural pause transcribes and sends on its own — no hotkey needed.
Solo mode
Continuous listening — one phrase, one send, tap again to stop.
Tap to start continuous listening. VAD marks each sentence, sends it instantly, never stops. Casting, reading chat, calling shots — one flow. Tap again to stop.
No matter the mode, the signal chain underneath is always the same
