@dholadipak09

Hello, I can build your WhatsApp assistant using the official WhatsApp Business API or Twilio, with reminders, document handling, and an extensible backend for future Mysa style features. I understand the core experience should happen fully inside WhatsApp, so users can set daily, weekly, or custom date reminders, upload PDFs, images, and Word files, and later retrieve stored documents without leaving the chat. I can build the webhook flow, reminder scheduler, file storage and labeling system, message templates, delivery handling, and a clean admin or backend structure to manage everything reliably. I can also keep the code modular so quick notes, expense logging, simple Q&A, and other assistant features can be added later without rebuilding the full system. I will deliver the working WhatsApp integration, source code, setup notes, and a short demo showing reminders and document upload or retrieval working. Best regards Ankit

@ApieTech

Hi — watched a couple of Mysa's YouTube clips, so the UX you're targeting is clear: everything stays inside WhatsApp, no separate app to open. Approach we'd take: Meta WhatsApp Business Cloud API as primary (cheaper at scale than Twilio for your volume, but Twilio is a one-line swap if you prefer), Node.js service for the reminder engine and intent routing, BullMQ for cron-style scheduled and recurring reminders with idempotent dispatch so users never get duplicates after retries. PDFs/images/Word files go through the WhatsApp Media API, stored in S3 with auto-generated labels (filename + sender + timestamp) and a simple keyword retrieval. A thin Android wrapper for users who want a one-tap settings/notes view. We've shipped real-time chat infra (WebRTC + chat sync) at APIE TECH, so the WhatsApp piece sits comfortably in that lane. Ping me with your number/sandbox and I'll come back with milestones.

@raiha2

I've worked on AI-powered automation systems, WhatsApp workflows, CRM integrations, and conversational assistants. For this project, I'd structure the solution around WhatsApp Business API/Twilio, a reminder engine for recurring and custom schedules, and a document layer that can store, categorize, and retrieve files directly from chat. The architecture will be designed to support future features like notes, expense tracking, and AI-powered Q&A without requiring a rebuild later. Happy to discuss the Mysa reference and map out the fastest implementation path.

@serviceaxisgroup

Hi, I can help with a fully working WhatsApp Android assistant that sends daily, weekly, and custom-date reminders, and lets users upload, store, label, and retrieve PDFs, Word files, and images in chat. I’ll start by defining the reminder scheduling flow and the Business API message/webhook handling, then build an extensible, well-commented architecture for notes, expense logging, and Q&A. To reduce risk, I’ll deliver early milestones: first the reminder scheduler firing reliably, then the document pipeline with quick retrieval. Which Meta-approved WhatsApp Business route do you prefer (official Business API or Twilio), and what message wording or command format should users use to set reminders? I can start as soon as you confirm these and share your target WhatsApp number.
