Case Study

Customer Support AI Agent

LLM assistant that resolved 95% of price requests without human intervention — achieved within eight weeks for an airline parts company.

Gmail integration
LangChain agent
SerpAPI + site search

The Challenge

The client received a high volume of price requests for aircraft parts. Each request required a human to read the email, locate the right part, check current pricing and stock, then craft a reply — a slow, manual process that delayed responses and tied up the support team.

Symptoms
What we observed
Slow response times on price queries
Shared mailbox backlog
Inconsistent pricing lookups

The Solution

We delivered a custom LangChain-based agent integrated with the client's Gmail account and price-request shared mailbox. The agent reads incoming emails, identifies the part, validates details via SerpAPI and on-site search, extracts current pricing and stock, then drafts and sends a structured reply via Gmail.
