Read chat, thank gifts, all on one screen
Danmaku, Super Chats, and gifts each get a column, with your live stats along the top. Double-click an event to mark it read, then turn on Hide Read Events to see only what you still owe.
Put it on stream with a single link
Add a browser source in OBS and paste the link; your whole configuration lives in it. The overlay can also follow your OBS scenes, switching to dark mode or another style automatically.
Endless spam, still readable
Card mode merges duplicate and similar danmaku into one card. Cards never move, and the one under your pointer never gets replaced.
Has this viewer been here before?
Click a username to see their danmaku, Super Chats, and gifts across your rooms, plus what they’ve spent in total, past usernames, and fan medals.
Keep the moments worth keeping
Export any event as a 2× PNG, or copy it straight to the clipboard. Blur usernames and avatars, and it’s ready to share publicly.
Filter events, GitHub style
Combine conditions on type, user, amount, or fan medal, and put a minus sign in front of one to exclude it. Add a date range, and that one message turns up fast.
Chat, read aloud
New danmaku are read aloud automatically, with gifts and Super Chats first. Connect any of several TTS services, or bring your own API.
Any language, translated live
A large language model translates danmaku and Super Chats into your language in real time, typos, puns, and internet slang included.
Works with OBS and VTS
Switch OBS scenes and manage your stream, or change models and trigger expressions in VTS and Persona, all from the dashboard.
