In short
GPT Researcher is a free, open-source agent that researches web and local documents to write detailed, cited reports using various LLMs.
GPT Researcher is an open-source autonomous AI research agent that gathers and validates information from multiple web sources in parallel to write detailed reports with inline citations. GPT Researcher supports various LLMs including OpenAI, Anthropic, Google, Mistral, DeepSeek, and local models via Ollama, along with retrievers like Tavily, Bing, Google, DuckDuckGo, and SearXNG.
The system uses a planner to split questions and run multiple researchers in parallel for each sub-question. Context filtering using Jev, BM25, or embeddings keeps only relevant passages before they reach the LLM. Research outputs can be exported to formats including PDF, Word, Markdown, JSON, and CSV.
GPT Researcher allows users to search local documents and conduct hybrid research using both local and web sources. The tool exposes research tools to MCP clients such as Claude, Cursor, and n8n.
