This AI Auto-Reply System for Customer Emails transforms your Gmail inbox into an intelligent support agent that works 24/7. It reads, analyzes, and replies to customer messages automatically — saving your team hours of manual email triage and improving response speed dramatically.

4️⃣ Contextual Understanding (Vector Search)

7️⃣ Logging & Analytics (Google Sheets)
