AI Lead Management System
Automated lead collection and qualification system built with n8n.
What it does

Normalizes data from both sources into a unified format

AI Customer Support Bot for a Bike Shop (Telegram)
A bike shop was handling 40+ daily customer inquiries manually — product availability, pricing, delivery and payment questions — taking up to 5 minutes per response.
Built a Telegram bot on n8n with two specialized AI agents powered by GPT-4o-mini. One agent queries the live product catalog via Google Sheets, the other handles store policies and FAQ via Google Docs. The bot supports both text and voice messages — voice is transcribed via Whisper before being passed to the agent. Session memory keeps conversation context across messages. A separate Error Workflow catches failures and sends instant alerts.
Result: ~70% of inquiries now handled automatically in under 10 seconds, saving the team roughly 60 hours per month.
