Mental health support remains inaccessible to millions due to cost, stigma, and the structural gap between weekly therapy sessions and daily life. This paper presents MindMate — a conversational AI wellness companion built entirely on no-code tools — that proactively reaches users via WhatsApp, interprets their emotional state using OpenAI GPT-4o, suggests evidence-based wellness activities, and logs all interactions in Google Sheets for ongoing reflection. The system uses n8n for workflow automation, Twilio for WhatsApp delivery, and Gmail API as an email fallback. Validation across 50 simulated interactions showed 94% mood classification accuracy and 98% workflow reliability. MindMate demonstrates that a zero-cost, no-code AI agent can meaningfully bridge the gap between formal therapy and everyday emotional self-care.
