Chat Translation

Translation

This feature is free to use under the fair use policy

This feature shipped on Mar 27, 2025

Features

  • Real-time translation backed by large AI models — on typos, wrong characters, homophone puns, and internet memes in particular, the quality beats nearly every machine translation service on the market
  • Low latency: danmaku of 40 characters or fewer are translated and returned within 1 second (p95)
  • A dual-layer cache 1, developed entirely in-house and miles ahead™ of the field, avoids re-translating the same content, cutting translation cost and your bandwidth cost without giving up quality

Usage

Open the dashboard, turn the feature on from the settings panel in the sidebar, then pick a target language under Translate to…. Besides common languages like English and Japanese, Chinese is available too, so you can follow danmaku from viewers writing in other languages

On-Demand Translation

This feature shipped on Jul 24, 2026

Even with real-time translation off, you can translate a single event on demand: click the username in an event to open the event menu and choose Translate, and the translation appears below that event

  • Danmaku (emote danmaku excluded) and Super Chats only
  • Requires a configured Login Sync Token
  • On-demand results share one cache with real-time translation, so identical content is never translated twice

Footnotes

  1. The dual-layer cache:

    • Local cache: translation results are cached in the browser via IndexedDB, so the same event is never translated twice
    • Remote cache: translation results are cached server-side via the Cache API, so the same content is never translated twice

    To clear the local translation cache, use the settings panel in the dashboard
