FR: inline message translation via Google Translate

[wux4an]

Is your feature request related to a problem?

Live chat is only useful if you can understand it. When users speak different languages, the conversation becomes confused for not english-speakers.

What solution would you like?

An inline "translate" option on chat messages that fetches a translation via the Google Translate unofficial API (translate.googleapis.com/translate_a/single) — no API key required. Similar to how Twitter/X and Telegram handle it: a keybinding (e.g. shift+t) on a selected message triggers translation inline, replacing or appending the translated text below the original.

Auto-detect the source language and translate to the viewer's configured locale.

What alternatives have you considered?

• DeepL — better quality but requires an API key and has usage limits.
• LibreTranslate — self-hostable and open source, but quality is noticeably lower for less common languages.

Google Translate's unofficial endpoint is the most practical starting point: free, no auth, fast, and widely supported.

Additional context

This would be opt-in per message to avoid cluttering the UI. Could also be configurable globally (auto-translate all foreign messages) for users who prefer it.

Example:

curl 'https://translate.googleapis.com/translate_a/single?client=gtx&sl=auto&tl=es&dt=t&q=hello'

Output:

[[["Hola","hello",null,null,10]],null,"en",null,null,null,1,[],[["en"],null,[1],["en"]]]
