Why BlackCat

Your customers message you on WhatsApp, LINE, Telegram and Zalo, in Thai, Arabic or Spanish. Your team shouldn't need five phones and a translator to keep up. BlackCat puts every account in one window, translates both ways and lets AI answer the easy questions, so your people can spend their time on the sales that need them.

New in v1.15.2

Save the important parts of a chat to the customer's notes

Right-click a message, photo, video, voice note or file in WhatsApp, Telegram or Messenger and choose "Save to notes". It goes into that customer's notes with who sent it and when, so prices, quotations and promises are easy to find later.

  • Text, photos, videos, voice notes and files
  • Your own note on every saved item
  • Play videos and voice notes and open files right from the notes panel
  • Stays on your computer and is never sent to the customer

Six tools that replace a desk full of phones

Stop switching devices, copy-pasting into translators and answering the same questions all day.

All your chat accounts in one window

Add WhatsApp, Telegram, LINE, Messenger, TikTok, Zalo and X accounts and work them side by side. Each runs in its own isolated session.

02 · Translation

Type in your language, send in theirs

Received messages appear in your language. Your replies go out in the customer's, automatically, in 65 languages.

  • Per account, or per customer
  • Real-time translation; Enter sends the translation, Alt+Enter your original
  • AI, Google and Lingva routes, with automatic fallback
See translation settings
03 · AI auto-replies

An AI that answers from your own product knowledge

Teach it with text, links, Excel, PDF, Google Sheets or video. It answers new chats and hands off to a person when it isn't sure.

  • Refine the reply style by chatting with the AI
  • Test with real questions before going live
  • Daily reply limit and hand-off message you control
See AI replies
04 · Assistant

Ask it, or tell it what to do

  • Reads chats, including photos and group senders
  • Prepares bulk lists and tasks on request
  • Always asks before sending or deleting
Meet the assistant

What users say

What changes when every chat is in one window

Sales and service teams in trading, logistics, education, retail and more on how they use BlackCat SCRM day to day.

One window, every account

I used to switch back and forth between several accounts, and customer messages slipped through easily. With everything in one window, following up is much easier.

Chen YuhangSales manager, trading company
See one window, every account →
Live translation

Translation is what I use most. When I talk with customers in different languages, I no longer copy text back and forth.

Jason L.Business manager, logistics

AI auto-replies

I like to see how the AI answers in the test area first, and only turn on auto-replies once I'm happy with it. That gives me much more confidence.

Daniel WongCustomer success manager, software services

Bulk messaging

Lists, message templates and tasks are kept separate, so preparing customer notices is more organised, and it's easy to check each item before sending.

Customer notes are really useful. We write down what the customer needs and the key points, so when a colleague takes over, it's all clear.
Lin WanqingCustomer service lead, cross-border e-commerce
We put common questions into the knowledge base first, then test the AI's answers. It's clearer which ones it can answer on its own and which need a person.
Xu JianingAdmissions consultant, education and training
What I discussed with a customer and what to bring up next time: with notes, I'm much less likely to forget. That detail suits everyday sales work.
Huang JunjieCar sales consultant
Quick replies keep our usual wording, and I adjust it for each customer. Replies stay consistent and I don't type from scratch every time.
Sophie T.Customer service lead, beauty and wellness
Customers ask about trips in different languages. Seeing the translation next to the original makes the context much easier to follow.
Wu XinyiCustomer consultant, travel
My biggest worry was messages scattered in different places. With my main accounts together, I don't keep hunting for windows when handling enquiries.
Su YutongOwner, online retail store
Each account can have its own alert settings, which is really practical. When I'm busy, I can adjust the chimes to suit my schedule.
Marcus C.Customer consultant, real estate
BlackCat Assistant is handy for repetitive settings. I just say what to change and check the result, which beats digging through menus.
Zhou KexinBrand operations and community support
The interface switches between Chinese and English, and dark mode is easier on the eyes when I handle messages at night. It fits the way I work.
Li Cheng'anExport sales manager, industrial equipment
