Breaking the Tower of Babel
Communicate in your natural language. WhatsApp messages translated automatically - write in English, the other side receives it in Chinese. They reply in Chinese, you read it in English. Simple as that.
In today's business world, we work with clients, suppliers and partners from around the globe.
But different languages create friction - unclear messages, embarrassing translations, and deals that get stuck along the way.
LS Duet doesn't reinvent the wheel - it simply connects people through WhatsApp, in their natural language.
No barriers, no misunderstandings, no embarrassing Google Translate moments.
Write in your language, the other side receives it in theirs. The original message is always preserved.
Set input and output languages for each contact individually. Everyone gets exactly what they need.
Not dry, mechanical translation. LS Duet translates the way you would write - natural, friendly, human.
Define a glossary for each contact - brand names, professional terms and jargon that shouldn't be translated, or need to be translated precisely.
Adding a Chinese contact, sending a message in English that arrives in Chinese, and receiving a reply in Chinese translated to English
Every incoming message is automatically translated to your language. Every outgoing message is translated to the contact's language. The original message is always accessible with a tap - so you can verify accuracy.
Works in groups too - with sender name and automatic source language detection.
Each contact gets a full profile: name, company, timezone, priority level, and communication language. See exactly what time it is for them, when you last spoke, and when it's time to follow up.
The favorites strip at the top provides quick access to your most important contacts.
Write now, send when convenient. Automatically detects timezones - so if Wei is in Beijing and it's 3 AM there, schedule for a reasonable hour. The message is automatically translated before sending.
Save important information from conversations - links, meeting summaries, notes. Organized by categories and tags, with quick search and a favorites system.
Every professional field has terms that shouldn't be translated - brand names, acronyms, professional jargon. And terms that need to be translated precisely, not the way Google thinks.
With LS Duet's glossary, define a custom term list for each contact:
The AI-powered engine identifies terms in your message and replaces them precisely according to your glossary, before the translation goes out.
5 simple steps and you're in. Let's begin.
Open the app and tap "Connect". You'll receive a Pairing Code - enter it in your WhatsApp under "Linked Devices". That's it, the connection is secure and encrypted.
Import contacts directly from WhatsApp with one tap - no manual typing required. For each contact, set the input language (what language they write to you in) and the output language (what language to translate your messages into).
Now just write in English (or any language you prefer). LS Duet will automatically translate every outgoing message to the contact's language, and every incoming message to yours. You can always view the original message.
Have an important message but it's 3 AM at the recipient's location? Write the message now, pick a date and time, and LS Duet will send it right on schedule - already translated and ready.
Found important information in a conversation? Long-press the message and choose "Save to Knowledge Base". The information is saved organized by categories and tags, with quick search when you need it again.
LS Duet supports 17 languages for automatic translation. The user interface is available in 7 languages.
Start communicating in your natural language. No barriers, no boundaries.
