How to Build an Internal Research Agent (in Python)

January 19, 20262 min readAnthony Oliko

The most common "White Collar" task is Synthesis. You read 10 articles, 3 PDFs, and 1 YouTube video, and then you write a 1-page summary for your boss. This is exactly what LLMs are good at.

In this guide, we will build a "Research Agent" that does this automatically.

The Architecture

We are not just using ChatGPT. We are building a system with Tools.

The Brain: GPT-4o (Or Claude 3.5 Sonnet).
The Eyes: Serper (Google Search API).
The Hands: Reader (A script to parse HTML/PDFs).

Step 1: The Stack

pip install langchain openai google-search-results

Step 2: The Search Tool

We need to give our Agent the ability to query Google.

from langchain.utilities import GoogleSerperAPIWrapper

search = GoogleSerperAPIWrapper()
results = search.run("latest trends in AI agent architecture 2025")
print(results)

Step 3: The "Deep Read" Loop

A simple search isn't enough. The Agent needs to visit the URLs.

def scrape_website(url):
    # Use your preferred scraper (BeautifulSoup or similar)
    # Extract text
    return text_content

Step 4: The Synthesis Prompt

Now we feed the raw text into the LLM with a specific instruction.

System Prompt: "You are a Senior Research Analyst. I will give you text from 5 sources. Your job is to ignore the fluff and extract the 3 most important 'Contrarian Truths'. Do not just summarize; analyze."

The ROI

I run this script every morning on my competitor's press releases. It takes 2 minutes to run. It saves me 45 minutes of reading time per day. Annual Saving: ~180 hours.
