Rostee: AI assistant on WhatsApp & Telegram
Conversational AI assistant on WhatsApp and Telegram that eliminates entrepreneurs' mental load: tasks, meetings, ideas, briefings and a productivity score, via text or voice message.

Productivity score
Context
Entrepreneurs juggle five tools to manage tasks, meetings and ideas, and spend more time organizing than executing. Rostee was born to run everything from a simple conversation.
The challenge
Build an AI agent able to understand text and voice messages in natural language, infer the right action among dozens (create a task, schedule a meeting, capture an idea, postpone a deadline...) and proactively follow up, on WhatsApp and Telegram, respecting each user's language and timezone.
The solution
I built a LangGraph agent (Claude Sonnet via OpenRouter, Whisper audio transcription) with 40 tools, wired to WhatsApp (Evolution API) and Telegram. Hono + Supabase backend, Stripe payment with automated onboarding, and scheduled routines: morning briefing, midday check-in and evening recap with productivity score and streak.
