What are GPT Researcher and PrivateGPT?
GPT Researcher
GPT Researcher is an autonomous agent that conducts in-depth web research on any topic and generates detailed, citation-backed reports. It aggregates multiple sources, filters for relevance, and produces structured output to reduce hallucinations and bias.
- Autonomous web research
- Cited report generation
- Multi-agent architecture
- Export to PDF and Word
PrivateGPT
PrivateGPT is a production-ready AI project that lets you ask questions about documents using LLMs entirely offline. It provides an API following the OpenAI standard and a Gradio UI for local RAG.
- Fully offline RAG
- OpenAI-compatible API
- Document ingestion
- No data leaves the host
