Everything a small team needs to sell in chat.

01
Visual flow builder

Drag a question, a condition, a delay. No code, and you can read the whole flow at a glance.

02
Bangla + English AI

Understands "koto taka", "ache ki", and Banglish spelling mistakes your customers actually type.

03
Orders inside the chat

Cart, address, and a bKash or Nagad link — the customer never leaves the conversation.

04
Human handover

The bot steps aside the moment someone is angry, and pings the right agent on their phone.

05
Broadcasts that land

Segment by what people bought, then send a template message that does not get your number blocked.

06
Numbers worth checking

Replies sent, leads captured, orders closed — per channel, per agent, per day.

Step one

Connect an account

Log in with Facebook or scan the WhatsApp QR. Two minutes, no developer needed.

Step two

Pick a ready flow

Start from Stock check, Order, or Comment to DM — then edit the words to sound like you.

Step three

Watch it close sales

Step in whenever you want. The inbox shows what the bot said before you arrived.

One screen for every conversation you have.

Shared inbox, assignment, notes and the automation history — side by side.

Your data

Your conversations stay yours.

Your customer list is the business. We treat it that way, and we put it in writing.

01We never train models on your customers’ messages — not ours, not anyone else’s.
02Ask for a copy of every subscriber, message and order and we will send it. No export fee.
03Ask us to delete it and it is gone within 30 days, backups included.
04When the assistant is not sure, it says so and hands the chat to a person. It will not invent a price or a stock count.

Questions we get every week.

Do I need a verified business account?+

For WhatsApp Cloud API, yes — we walk you through Meta verification and it usually takes a day or two. Messenger, Instagram and Telegram work right away.

Will the bot answer in Bangla?+

Yes — Bangla, English and Banglish. You write the tone once and the AI keeps it, including when someone types "koto taka" with three spelling mistakes.

What happens when I run out of conversations?+

Nothing breaks. Automation keeps replying and we tell you the overage before we charge it — no surprise bill at the end of the month.

Can my team reply from their phones?+

The inbox is built for small screens, and assignment notifications arrive as push. Agents never need your Facebook password.

Your next customer is typing right now.

Set up the first flow tonight. Free while you test it, and you keep every conversation you capture.
