GPT Researcher is an open-source agent that handles the heavy lifting of online research. Give it a topic and it collects material from multiple sources, organises the findings and produces a long-form report with citations you can check.
Because the code is on GitHub, developers can plug it into their own applications or multi-agent systems. It has an active community of contributors. Students and analysts can use it free of charge to cut down the hours usually spent gathering and sorting sources.
