Pros
GPT Researcher
  • The tool is MIT licensed and free to use.
  • Users can connect any LLM of their choice, including OpenAI, Anthropic, Groq, Llama 3, and Hugging Face.
  • Research outputs can be exported to formats including PDF, Word, Markdown, JSON, and CSV.
  • The system uses a planner to run multiple researchers in parallel for each sub-question.
  • The tool supports hybrid research using both local documents and web sources.
Open Deep Research
  • The tool supports local LLMs via configurable endpoints and model names.
  • Configurable parameters allow users to control the breadth and depth of the research.
  • The system handles multiple searches and result processing in parallel for efficiency.
Cons

Editorial score: rule-based, 0–10, from AI-assisted profile inputs (see /methodology) — not a user rating; “—” means unscored. “Not listed” means we have no record of it, not that it is absent. GitHub figures and prices carry the date they were checked or captured; prices are shown as published, unconverted.
