WhatsApp Web has no translate button
WhatsApp’s own translation lives in the phone apps. On a computer, the usual workaround is copying each message into a translator tab and pasting the reply back, and no real conversation survives that for long. Kaption translates inside the chat, in both directions.
How to translate a chat
- 02
Turn on Live Translation in the chat
Open the conversation and click the Live Translation button. It stays on for that chat until you turn it off.
- 03
Pick your language
Choose the language to translate into. Messages from the other person appear in it, with the original text still there to check.
- 04
Reply in your own language
Type as usual: Kaption detects your contact’s language and shows the translation as you type, so you can check it before you send.
The details
36 languages
English, Spanish, French, German, Italian, Portuguese, Russian, Japanese, Chinese, Korean, Arabic, Hindi, Turkish, Dutch, Polish, Swedish, Danish, Norwegian, Finnish, Czech, Slovak, Hungarian, Romanian, Bulgarian, Croatian, Serbian, Slovenian, Ukrainian, Hebrew, Vietnamese, Thai, Indonesian, Malay, Persian, Bengali and Tamil.
Both directions
Incoming messages are translated where they sit in the chat; your reply is translated before it goes out, so the other person reads it in their language.
Voice notes, too
Transcribe a voice note first, then translate the text. Kaption does both in the same chat.
What leaves your computer
Only the text you translate, with a language hint, and without your name, number or contacts. It is not kept after the translation comes back, and it is never used to train AI models.
On the desktop app
The Kaption desktop app for Mac (Apple silicon) and Windows 10/11 translates the same way, and on a Mac with macOS 26 translation can run on the computer itself.
Where it slips
Slang, irony and unusual names. When a price, a date or a promise is at stake, check the original text.
Plan and limits
Every account starts with 60 days of Business, translation included. After that, Lifetime local AI translates on your computer, unlimited, with smaller models; Pro, Business and Business Agent translate in the cloud, unlimited, along with unlimited transcripts and summaries. Free continues with limits on voice notes. See plans and prices
Questions
How do I translate a WhatsApp message?
On a computer, install Kaption, open the chat in WhatsApp Web and turn on Live Translation: each message appears in your language, and your reply is translated before you send it. On a phone, the WhatsApp app can translate some messages itself, depending on the device and the language; WhatsApp Web has no translate option of its own.
Is there a free translator for WhatsApp?
Yes, to start: every account gets 60 days of Business, translation included, with no card. After that, Free continues with limits on voice notes; Lifetime local AI translates on your computer without limits for one payment, and Pro and Business make cloud translation unlimited.
Does the other person see my message in their language?
Yes. You write in your language, Kaption shows the translation before you send, and the translated message is the one they receive.
Can it translate voice notes?
Not directly from the audio. Transcribe the voice note first, then translate the text.
Does it work on WhatsApp Business?
Yes. Kaption works with personal and WhatsApp Business accounts in WhatsApp Web and in the desktop app.
