How Cogent’s Agentic AI Revolutionizes T&E Reporting with RAG

Transform Your T&E Management with the Power of AI and Retrieval-Augmented Generation

Are you tired of searching through countless dashboards and documents to find a simple answer about a travel policy or expense limit? You're not alone. Travel managers and finance teams at large corporations spend countless hours on inefficient information retrieval, a major pain point that delays critical decisions and frustrates employees. The solution lies in a powerful AI technique known as Retrieval-Augmented Generation (RAG), the secret behind Cogent's ability to provide instant, data-driven insights.

At PredictX, we believe in Data Consolidation & Insights that empower you to become a strategic leader, not just a data custodian. Cogent’s Agentic AI workforce goes beyond simple reporting, serving as your new best friend for transforming T&E Reporting. It’s a category-defining product that has even won the 2025 BTS Europe Innovation Faceoff award and was featured on the Business Travel Magazine’s Tech Hotlist.

What is RAG? A Game-Changer for Travel & Expense Reporting

Imagine a brilliant but isolated scholar (the Large Language Model) who knows everything about the world but has no access to your company's specific knowledge base. Now, imagine a meticulous, highly-organized librarian (the RAG system) whose only job is to provide that scholar with the exact, relevant books they need, instantly.

That's the essence of RAG. It's not about making the AI guess the answer; it's about giving it the specific, verified information it needs to construct a perfect, on-point response. This is how we ensure that answers are not only fast but also accurate and trustworthy.

From Data to Answers: The Four Steps of RAG in T&E Management

Step 1: Chunking – Structuring T&E Data for AI 

Instead of trying to process an entire 100-page corporate travel policy document at once, we break it down into smaller, digestible "chunks." This makes it far more manageable for the AI to pinpoint the exact information required. For example, a single document is transformed into hundreds of organized pieces, such as "Meal Expense Limits" or "Booking Approved Hotels".

Step 2: Embedding – The Key to AI-Powered T&E Analytics 

Computers don't think in words; they think in numbers. Embedding is the process of converting each text chunk into a unique numerical representation called a vector. Think of this vector as a digital fingerprint. The magic of this process is that chunks with similar meanings have vectors that are numerically "close" to each other. For instance, "business travel meal expenses" and "per diem rates for food" would be very close in this vector space, making them easily retrievable in a similarity search.

Step 3: The Vector Database – The Engine for Instant T&E Search

All of these numerical fingerprints are stored in a specialized vector database. Unlike a traditional database that uses keywords, a vector database is optimized for a similarity search. When you ask a question like, "What's the policy for expensing meals on business trips?", the system converts your query into its own vector and instantly finds the most similar chunks from the entire database.

Step 4: Reranking – Ensuring Precision in Your T&E Reporting 

To ensure maximum accuracy, an optional but crucial step is reranking. This process takes the top-ranked chunks from the similarity search and re-evaluates them more carefully, pushing any less relevant information to the bottom. This ensures that only the most relevant and accurate information is sent to the Large Language Model for synthesis.

Putting RAG into Action: Cogent’s Real-World Impact on T&E Reporting

Let's see this in action. A travel manager at a large corporation needs to answer a question that's a common pain point: "What is the policy for expensing meals and hotel stays during business travel?".

1. The Query Arrives: You type your natural language question into Cogent. The system's Conversational Intelligence recognizes the query and sends it to a document agent that uses RAG.
2. Searching the Database: Your question is instantly converted into a vector, and the system performs a lightning-fast search. It finds two highly relevant chunks from the travel policy:
   
   • Chunk A: "Employees can expense up to $75 per day for meals on domestic travel. A per diem rate applies to international trips."
   • Chunk B: "All hotel bookings must be made through the approved corporate booking tool to be eligible for reimbursement."
3. Refining the Results (Reranking): Cogent’s reranking model confirms that both chunks are highly relevant to your query about meals and hotels.
4. Generating the Response: The system sends these verified chunks to the Large Language Model. The LLM then synthesizes the information into a single, cohesive answer, providing clear guidance on both meal and hotel policies.

This process ensures that the answer is accurate, up-to-date, and draws from all the necessary information, regardless of where it was located in the original document.
