WhatsApp Web, in your language — without leaving the chat.

Free account to start · plans from $5/mo.

Chat in your language
Every WhatsApp Web message is translated automatically, in real time.
What the panel looks like
The original chat stays intact on WhatsApp Web; the panel translates live and lets you reply in your own language.
Features
Sorted by what matters most: reading and replying without leaving the chat, both ways.
Live chat translation
The side panel translates the latest messages and keeps translating new ones as they arrive, while the original chat stays right there, intact and interactive.
Translate and paste
Write your reply in your own language. It gets translated into the other person's language and pasted straight into WhatsApp's text box — both ways, not just reading.
Voice notes, transcribed in your browser
Whisper runs locally: audio never leaves your machine. It's transcribed right there and then translated.
Group chats, no mixed-up messages
Every sender is identified in the translation, message by message.
Translation cache
A message translated once won't spend credits again.
Per-chat history
A dedicated panel to review past translations for each conversation.
Message privacy
Text is sent temporarily just to translate it; it isn't stored as plain text on the server beyond the credit-usage log.
Plans
1 credit is roughly 100 translation tokens. Free to start, a monthly plan to keep going.
Ran out of credits before renewal? Buy a one-time top-up of 1,000 credits for $1 without changing plans — fully automatic via PayPal, right from the dashboard.
Frequently asked questions
Do I need anything besides the extension?
Yes: an account on the web dashboard and your own API key, which you generate after signing up and paste into the extension.
Is it available on the Chrome Web Store?
Not yet. For now it installs as an unpacked extension (developer mode) directly from the package we share with you.
What happens to my messages?
They're sent temporarily to the AI provider just to translate them; they aren't stored as plain text on the server beyond the credit-usage log.
What about voice notes?
They're transcribed right in your own browser — audio is never uploaded to any server — and then translated.
How do I add credits?
Pick a monthly plan (credits are added automatically every month via PayPal) or buy a one-time top-up of 1,000 credits whenever you need it — both options live in the dashboard, under /recargas.
