From a Chinese draft to a professional message: how the product works

Bridgyu (桥语) is a WhatsApp communication tool for export companies in China. It does one thing: lets you talk to overseas buyers in Chinese, with confidence. Below we follow one typical message from draft to sending, then explain the checks behind each step and the things we deliberately don’t do.

Step 1: Write in Chinese, however it comes

Type what you want to say. It can be casual, a few short fragments, or full of model numbers and figures, for example:

You don’t need to work out the foreign-language wording first, and you don’t need to write formally. There is just one piece of advice: be clear about the facts. The more precisely you write prices, quantities, dates and currencies, the more reliable the translation and the checks that follow. Translation works between Chinese and other languages, so the message goes out in whatever language your buyer uses.

Step 2: AI translates and polishes

Based on the language in the contact’s profile, the system turns your note into a proper business message. Translation involving Chinese is done by DeepSeek. Polishing means adding the greeting and linking words a quick note leaves out, turning short fragments into a smooth paragraph, and keeping the tone polite and professional.

Polishing shouldn’t change the facts. Prices, quantities, dates, model numbers and trade terms must stay as you wrote them, and whether they really did is not left to the model: the rule-based comparison in step 3 checks it.

Step 3: Back-translate into Chinese and check

A different model (OpenAI) independently translates the message back into Chinese, so you can see what the buyer will actually read. Using a model from another vendor avoids the same model carrying its own misunderstanding straight back.

At the same time, a deterministic set of rules (not AI) compares the numbers in your original and in the translation one by one, including 万 and 千 and local formats such as 5.000 vs 5,000, as well as currencies, units, dates, times and Incoterms. Here is a quote message with numbers in it:

Anything that doesn’t match is highlighted in the confirm window.

Step 4: You approve, then it sends

The confirm window shows everything about this send:

• the sending account (which company WhatsApp number it goes from) and the recipient;
• your Chinese original, the translation the buyer will receive, and the back-translation;
• the result of every check.

The default choice is Cancel. Pressing Esc or clicking outside the window also cancels. The message goes out only when you click Approve yourself. If the facts check finds a difference, you also have to confirm explicitly that you have checked it before you can approve.

What is checked before sending

Besides the translation itself, every send goes through a set of checks. If any of them fails, or can’t run for any reason, sending is blocked. There is no “send it anyway and see”.

All of these follow the same rule: when in doubt, don’t send.

New organizations start in test mode

A newly registered organization starts in test mode, where messages can only go to numbers on an allowlist, such as your own phone and your colleagues’. That lets you run the whole flow a few times on a real WhatsApp account: write in Chinese, read the translation and the back-translation, try amounts written with 万 and 千, and see how the checks display them. Once you are comfortable, you can start talking to buyers.

Things we deliberately don’t do

• No automatic sending. There is no one-click send; every message needs your approval.
• No scheduled or bulk sending. No timed sends, and no sending to many contacts at once.
• Replies only in conversations the buyer started. Messages go only into conversations where the buyer contacted you first. The tool isn’t for sending first messages to strangers.
• No new numbers. You link your company’s existing WhatsApp accounts with a QR code, and buyers keep seeing the same number.

These limits can make the product feel slower in some situations. We think that in export communication, having a person approve every message matters more than sending a few more of them.

The WhatsApp connection and account risk

The WhatsApp connection is made through Green API. Green API is not an official WhatsApp interface, so there is always some risk that WhatsApp restricts a number. We will never promise that a number can’t be restricted, and if any tool does promise that, it’s worth asking how.

No automatic sending, no bulk messages and replies only in buyer-started conversations steer clear of many high-risk ways of using WhatsApp, but they can’t bring the risk to zero. For important buyers, keep another channel, such as email, as well.

AI translation is included in your plan

Translation, polishing and back-translation are all included in your plan under fair use. There is nothing to count and no packs to buy, and normal business use never reaches the limit. If your team’s usage is very heavy, just contact us.

For teams

A team can bring several company WhatsApp accounts into one inbox. Admins can view and take over any conversation, and every action is recorded in the audit log. The number of accounts and members is set out on the pricing page.

Who it is for, and who it isn’t

• For: export sales staff and teams who use WhatsApp to discuss quotes, samples, lead times and payment with overseas buyers, especially people who aren’t fluent in the buyer’s language and can’t afford mistakes on the key facts.
• Not for: bulk marketing, auto-reply bots or scheduled broadcasts. We deliberately don’t build those.
