GPT Researcher is an open-source autonomous AI research agent that conducts comprehensive online research on any topic, synthesizing information from multiple sources into detailed, factual research reports. The agent autonomously formulates search queries, browses websites, reads and evaluates source content, and compiles well-cited research documents — tasks that typically take human researchers hours. GPT Researcher produces longer-form research outputs than standard AI search tools, with proper citations, multiple perspectives, and structured analysis suitable for academic or professional use.
