AI Agent for Research: Deep Research You Can Run Yourself
An AI agent for research gathers sources, evaluates them, and writes a cited report. We compare gpt-researcher, AI-Scientist and the practical setup.
💡 What You Will Learn
An AI agent for research gathers sources, evaluates them, and writes a cited report. We compare gpt-researcher, AI-Scientist and the practical setup.
Research is hours of tab-opening, note-taking, and source-hoarding before you write a single sentence. An AI agent for research automates the gathering and synthesizing - then hands you a cited draft you can verify instead of starting from zero.
The Tools
gpt-researcher (assafelovic/gpt-researcher, 28,855 stars) is the go-to autonomous research agent: it takes a question, plans sub-queries, searches the web, evaluates source credibility, and writes a report with citations. It runs with local LLMs via Ollama (177,902 stars) for fully private research. Sakana AI-Scientist (14,352 stars) goes further - it proposes hypotheses, runs experiments, and writes papers, aimed at ML research workflows.
Practical setup: run gpt-researcher with your own API key, give it a focused question (narrow beats broad), and always verify the citations - it synthesizes well but source quality varies. For company or market research, feed it internal documents plus web search for grounded results.

FAQ
Q: Can I trust AI research reports?
A: Treat them as a strong first draft. Verify every citation before using the content - hallucinated sources are the main failure mode.
Q: How is this different from asking ChatGPT?
A: The agent searches iteratively, evaluates multiple sources, and structures a cited report - better for broad questions that need synthesis.
