Translate Gmail in Your Browser, Both Ways

To translate Gmail both ways, add a browser extension that works inside mail.google.com. Incoming emails are translated in your language in place, and you write the reply in your own language and translate it in the compose box before you send, so a cross-language email thread stays in one window instead of a separate translator.

Why generic translators break on Gmail

Gmail is where business gets decided, and a reply that reads like a machine translated it undercuts the message. Copy-pasting a long email into a translator tab, then pasting your reply back, is slow and error-prone in a rich compose box that reformats pasted text. Email needs the right register, not just the right words.

Reading Gmail in your language

Read incoming emails in your own language, side-by-side with the original or replacing it in place, so a long thread in another language is readable at a glance.

Writing back in theirs

Write the reply in your own language directly in the Gmail compose box and let Input Translation send it in the recipient language, with a Business tone that keeps a client or partner email properly formal.

This writing half is what most translators skip, they only translate what you read, not what you send. It runs across all four core features: page translation, input translation, selection translation, and AI text-to-speech, in 100+ languages.
