AI That Sounds Like Us, Not Everyone Else 

As we got more comfortable with AI, we started brainstorming across the agency to see where AI could have the biggest impact for us. Out of these conversations, Assemblē took shape.

We knew we wanted Assemblē to enhance the outputs of well-known LLMs with a custom RAG (retrieval-augmented generation) function. We built an application that allows users to upload past proposals and then makes those documents available to an LLM as context. Our technology team orchestrated a suite of tools that handle everything from secure storage to intelligent document processing and natural language search capabilities.

As soon as a document is uploaded, AI smartly breaks it down into manageable knowledge chunks. When a user chats, AI powers a natural language search for related documents and then uses our unique system instructions, the related documents, and the chat history to generate a response.

We’ve created a solution that combines the power of leading LLMs with secure access to our institutional knowledge. This architecture streamlines our proposal process while safeguarding what makes MBB unique.

Assemblē’s architecture isn’t just about efficiency. By relying on our in-house technical expertise, we’ve created a system that let’s MBB’s AI-generated drafts remain distinctively MBB.

We’re proud of our brand voice. When we’re introducing ourselves to a potential client, we want our candidness and quick wit to shine through. As any regular reader of our blog knows, AI can have a flattening effect on a verbal identity. At MBB, our perspective is part of our value proposition. We need Assemblē to keep MBB sounding like MBB.

To align our AI assistant’s outputs with our voice, we built a customizable system prompt into Assemblē. Think of it as a brand guide that shapes every interaction.

Our system prompt nudges the output toward our voice, offers guidelines for handling knowledge gaps (an early version would creatively–but inaccurately–invented clients and case studies when uncertain), and limits the scope of what “full-service advertising agency” could mean to more directly reflect our expertise and services. Unlike public AI tools, every conversation with Assemblē begins with these brand-preserving instructions.

As our brand evolves or we discover new ways to enhance its performance, we can deploy changes instantly across the platform. Our team members can focus on crafting winning proposals and not worry about being prompt engineering experts. Behind the scenes, we ensure Assemblē remains aligned with our strategic goals and distinctive voice. Our solution offers a level of customization nearly unobtainable with off-the-shelf AI.
