Building an Intelligent Research Assistant: An Agentic Web Research System Based on Gemini and SerpAPI

This article introduces an open-source full-stack intelligent research application—Agentic Research System. It combines the Google Gemini large language model and SerpAPI real-time search, uses an agent architecture to implement an automated in-depth research process with multi-step reasoning, addresses the core challenge of knowledge workers efficiently acquiring, integrating, and analyzing online information in the era of information explosion, and finally generates structured in-depth analysis reports.

The Agentic Research System is based on an agent architecture, simulating the thinking process of human researchers. It uses a multi-step reasoning mechanism to understand the deep intent of user queries, actively search for information, and generate reports through comprehensive analysis. Its uniqueness lies in the 'agent workflow' design, which goes through four stages: intent analysis, real-time search, multi-step reasoning, and comprehensive reporting, resulting in structured research outcomes.

Frontend Tech Stack

The user interface is built with React+Vite, uses Tailwind CSS for responsive design, Framer Motion for animations, Lucide React for icons, Recharts for visualization, and supports glass morphism style and dark mode.

Backend and AI Layer

The backend uses FastAPI for asynchronous request processing, SQLAlchemy+SQLite for persistence, and JWT for authentication; the AI core integrates Google Gemini (intent understanding, analysis generation) and SerpAPI (real-time search to supplement timeliness).

Deployment and Operations

It uses Docker containerization and Docker Compose for orchestration. After configuring the API keys, execute docker-compose up --build to start the service.

1. Intent Analysis Stage: The Gemini model identifies the core goal of the user's query (e.g., technical analysis, trend prediction, etc.);
2. Real-time Web Search: Obtain the latest data via SerpAPI to make up for the lack of timeliness in LLM knowledge;
3. Multi-step Reasoning and Synthesis: Gemini filters and deduplicates information, simulates the human analysis process (identifies arguments, compares viewpoints, correlates information) to form a logically coherent analysis;
4. Report Generation and Auditing: Outputs a report in Markdown format and saves audit logs to ensure result traceability.

Typical Scenarios: Preliminary literature research for academic studies, market research for business analysts, competitive product analysis for technical personnel, and knowledge acquisition in unfamiliar fields.

Usage Process: Register an account → Enter a query on the dashboard → View the agent's execution steps in real-time → Obtain the complete analysis report → Form a personal knowledge base by reviewing historical records.

The project is open-sourced under the MIT license, with a clear code structure and complete documentation. It provides a fully deployable application, demonstrates to developers how to build an LLM agent system, and its architecture design can serve as a reference template for multi-tool collaboration, state management, streaming response processing, etc. It covers a full-link practical case including frontend interaction, backend services, AI integration, and DevOps deployment.

The Agentic Research System represents the development direction of AI-assisted research tools from passive response to active exploration, from single modality to multi-source fusion, and from instant answers to in-depth analysis. With the improvement of LLM capabilities and the advancement of search technology, such intelligent research assistants will play a more important role in the field of knowledge work, and mastering such tools is a key skill for knowledge workers to improve productivity.
