Building a research agent that goes beyond generic summaries requires moving past standard AI tools like ChatGPT. Instead of relying on broad web searches, the goal is to create a specialized system that scours vast amounts of tech content, filters it based on a user’s unique interests, and surfaces actionable insights. The key difference lies in the data source. Most AI models lack access to curated, structured data. Without this foundation, even advanced LLMs produce shallow results. The agent described here works because it’s built on a robust, pre-processed data pipeline that ingests thousands of tech forum posts, articles, and discussions daily. This pipeline uses lightweight NLP models to extract keywords, categorize content, and analyze sentiment. It tracks trending topics over time and identifies which ones are gaining traction. For each keyword, a dedicated endpoint gathers the most engaging posts, processes them in chunks, and extracts key facts—keeping source references intact. These facts are cached, so repeated queries return in milliseconds, keeping costs low. The system uses prompt chaining to maintain accuracy. First, small models parse and filter data. Then, a final LLM synthesizes the facts into themes and summaries. This layered approach ensures precision while minimizing expensive model calls. User personalization is central. The agent starts by collecting a profile—interests, role (e.g., developer, CMO), preferred depth of detail, and time frame. A structured prompt translates this into a JSON schema with defined fields: personality, categories, keywords, time period, and summary style. This output is stored and reused, allowing the system to tailor every report. When a user triggers a report, the agent retrieves their profile, fetches relevant trending keywords, and pulls pre-processed facts. It combines results, removes duplicates, and links each insight to its source. Then, two LLM steps follow: one to identify top themes based on relevance to the user, and another to generate concise and detailed summaries with titles. The entire process takes a few minutes—longer only if new data needs to be fetched. Once cached, future requests are nearly instant. The final output is a clean, well-structured report with citations, ready for action. This approach demands more engineering than typical AI applications. It’s not about letting the model “figure it out.” Instead, it’s about building a reliable system where the LLM acts as a translator and synthesizer, not a searcher. Small models handle data processing, while larger ones focus on high-level reasoning. This agent runs in Discord but could be adapted to any platform. The full code is available on GitHub. You can also join the Discord channel to test it without setting it up. While this is one implementation, the core principles apply broadly: strong data pipelines, caching, structured outputs, and thoughtful prompt design. LLMs don’t eliminate the need for software engineering—they make it more powerful when combined with good architecture. If you're building agents, focus on control, consistency, and relevance. Let the AI do what it does best—understand and synthesize—while you handle the data and workflow.
