Translate Telegram Web Messages in Both Directions

Telegram can translate messages you read, but it does nothing for the replies you write. To handle Telegram Web in both directions you add a browser extension that renders translations inline: incoming messages and group chats show up in your language in place, and you reply by typing in your own language and sending it in the recipient's, without leaving the chat.

Telegram is where a lot of cross-language communities live, crypto groups, trading channels, fan communities, cross-border deal chats. The reading side is half solved; the writing side, sending a natural reply in another language, is the half that still breaks the flow.

Why the built-in translation is only half the job

Telegram's own translation helps you understand an incoming message. It does not help you answer in the sender's language. So the moment you want to reply, you are back to copy-pasting your draft into a separate translator, then pasting the result into the message box, one message at a time.

What removes that friction is inline rendering plus input translation: the incoming message is translated where it sits, and your reply is translated in the input box before you send it. Reading and writing, both inside Telegram Web.

Reading incoming chats and groups

Swiftin translates any webpage in your Chromium browser, including web.telegram.org. Two reading modes are available:

• Bilingual (side-by-side), the original message stays visible with the translation under it, handy for busy groups where you want to verify a term.
• Translation-only (replace in-place), the original is swapped for the translation, cleaner for scrolling a fast-moving channel.

Auto-translate keeps a busy group readable without clicking each message. Both reading modes are on the Free plan.

Replying in the recipient's language

Reading is the easy half. Swiftin ships Input Translation for the hard half: type your reply in your own language in Telegram's input box, trigger the translation, and the message updates in place with the translated version. Review, edit if you want, send.

Pro and Team plans add three tone styles (Normal / Slang / Business) with intensity control, so a casual group chat and a business negotiation read differently.

Privacy on Telegram Web

Once a message is visible in your browser, translating it sends that text to the translator. Swiftin does not store translations on the server by default, opt-in server-side history is available to Team owners only, while Free and Pro keep any history on-device. For private groups and deal chats, the no-history default keeps the workflow clean. See the full privacy explainer for what "not stored" means in detail.
