The Challenge

A US-based startup serving boat enthusiasts wanted to combine product sales with expert-level maintenance advice using a conversational interface. The challenge? Boat engine troubleshooting is complex, manuals are long, and product recommendations need to be timely, contextual, and relevant. The firm needed a solution that could provide real-time, expert guidance while subtly driving ecommerce conversions.

A Day in the Life: Before Our Solution

Boat owners faced cryptic engine issues with no easy answers. They flipped through dense OEM manuals, posted on forums hoping for guidance, or paid for slow, expensive expert calls.

Meanwhile, the ecommerce site spit back generic parts recommendations (“propeller,” “oil filter”) that ignored the user’s exact engine model, maintenance history, or current fault. Frustration peaked, chat windows went cold, and abandoned carts piled up, along with missed revenue and dissatisfied customers.

Pain Points:

Boat owners struggled to find model-specific answers for engine and maintenance issues.
Generic product recommendations often lacked context about the boat model, engine, and reported fault.
Getting expert maintenance guidance was slow and often required direct support from specialists.
Uncertainty around the right parts or products contributed to chat and cart abandonment.
There was limited feedback from customer interactions to continuously improve recommendations and support.

Solution

Tatras built a GenAI-powered chatbot that served as both a troubleshooting expert and a product recommender. It could interpret complex queries, provide targeted repair guidance, and suggest the exact tools or parts a user needed.

1. Core Innovation

At the heart of the solution was a multi-agent architecture powered by Retrieval-Augmented Generation (RAG). Each agent specialized in interpreting manuals from different OEMs, accessing structured product and CRM databases, and refining answers through inter-agent collaboration. The chatbot also continuously learned from handoffs to human experts, making it smarter with every interaction.

2. Key Features

Multi-agent system with domain-specific expertise (OEMs, engines, CRM, product catalog)
RAG architecture combining structured and unstructured data
Contextual product recommendations based on real-time queries
Dynamic follow-up for recommendation refinement
Video and guide integration from open-source boating resources
Human handoff fallback with learning loop

3. Workflow Integration

The chatbot was deployed on the client’s ecommerce platform and connected to both internal product databases and CRM systems. New users could register, describe their issue, and immediately receive a diagnostic suggestion or parts recommendation. The team could also monitor and update the system through a backend interface, ensuring continuous performance tuning.
