## The Hook

GPT Researcher is an open deep-research agent: planner and execution agents break a task into questions, research the web or your local documents, and write a detailed report with citations.

## What's Good

Apache-2.0 (assafelovic/gpt-researcher), release v3.7.0 (2026-09-26). Works with many LLM providers and search backends, and runs as a Python library, a CLI or a web app. Highly customizable for domain-specific research agents. ★~30.2k.

## The Catch

Each report makes many LLM and search calls, so costs add up with paid APIs. Report quality depends heavily on your model and search provider. Check citations before you trust a report.

## Verdict

The most established open alternative to hosted deep-research tools.
