Discord Translator translates a whole channel into your language — including the messages already above you, not just new ones — from one toggle in the chat view.
Turn it on per server. Messages appear translated in place, and you can switch between replacing the original and showing both languages together. Double-click a word or triple-click a sentence to translate just that selection, and click again to see the original.
15 target languages. Mentions, custom emoji, code blocks, spoilers, timestamps and links are protected and come back exactly as they were.
Translation uses Google's public endpoint by default — no account, no key, nothing to sign up for. DeepL is available if you supply your own API key.
