AI assistant for WhatsApp Web and Slack
GrowTalkAI brings a smart assistant into WhatsApp Web and Slack for people who think in Bangla but chat in English: understand every message, reply with confidence, and never lose context.

01 · Problem
Many people read and think in Bangla but have to hold client conversations in English — misreading a message or sending a clumsy reply costs trust, and important details get buried in long chats.
02 · Solution
An extension that works inside WhatsApp Web and Slack: it translates incoming messages, explains unclear ones, turns Bangla or Banglish into clean English with spelling and tone checks, suggests replies, summarises chats and keeps memory notes for important conversations.
03 · Outcome
Runs on free AI providers — Google Gemini, Groq and OpenRouter — with the user's own keys, switching automatically when one is busy or out of quota; private chats only use providers that don't train on messages.
What I shipped.
Built end-to-end: the extension, the in-page UI for WhatsApp Web and Slack, the provider routing and the settings popup.
