Hey Skool fam, I want to share what I’ve been building using n8n + AI + Vector DBs to automate multilingual AI responses on WhatsApp & Telegram — with text-to-speech voice replies and database logging.
Built this with n8n, OpenAI, Pinecone, ElevenLabs — here's what it does:
âś… Multi-Platform AI Assistant
- Connected to multiple WhatsApp numbers + Telegram bot.
- Listens to text & audio messages from users.
âś… Multilingual Understanding & Reply
- Detects user language automatically.
- Replies back in the same language.
- Can respond as text or human-like audio (via ElevenLabs).
âś… Smart Context & Knowledge Retrieval
- Classifies every user question to the right Pinecone namespace.
- Uses OpenAI large embedding 3 for better search accuracy.
- GPT-4 generates answers strictly from internal knowledge base (no AI guessing).
âś… Clean Automation Flow
- Transcribes audios.
- Formats for voice output.
- Sends replies.
- Logs everything to Airtable.
It’s now handling WhatsApp + Telegram questions in multiple languages with contextual AI-powered answers.
