It translates your Twitch chat, reads it aloud in the right voice for each language, and answers your viewers' language questions — all on your own machine.
Real chat is short, mixes languages mid-sentence, and is full of noise. Most bots quietly drop exactly those messages.
Read as an English question quoting a Japanese term, so it travels outward to your audience instead of being translated back into English. Four kanji don't outvote a whole English sentence.
Stays Japanese. One borrowed English word doesn't flip the direction.
Five letters is enough. Short greetings are the most common message in chat, and the one most bots fail on.
Recognised as shorthand and skipped. No API call, no nonsense translation.
When local detection can't name a language, the engine's own detection decides — and can correct the route afterwards.
Repeats come from a local cache. Engines are tried in order, so one provider going down doesn't stop your stream.
One message is often bilingual. Reading it with a single voice mangles half of it.
Split into a Japanese run and an English run, each spoken by its own voice.
Answered briefly enough to read while you're live.
^a“Ichigo ichie means every encounter is unique and will never happen again.”
^g“I have a pen. The subject ‘I’ takes ‘have’, not ‘has’.”
^n“Yabai is versatile casual slang — terrible or amazing, depending on tone.”
^aiShort and direct, and says so when it doesn't know.
Every AI call is triggered by a viewer and costs money. A per-viewer cooldown, a channel-wide ceiling, and a concurrency cap are part of the design — not options you must remember to switch on.
If a request never reaches a provider, the viewer gets their cooldown back instead of being charged for a failure that wasn't theirs.
A second window with just chat and translations. Adjustable reading size and background transparency, optional always-on-top, hideable title bar.
Authorize Twitch once, pick two languages, choose private or public translations. Everything else has a sensible default.
The app and its guide are written in English, Japanese, and Traditional Chinese.
Kaomoji, mood detection, and translation style presets, so the bot sounds like part of your channel.
Credentials are encrypted by the operating system, never left in plain config files. Local voices mean chat audio never leaves your PC.
Paid providers are upgrades, never requirements.
