Open-source Consensus alternatives

GPT Researcher is an open-source autonomous agent that performs deep research on a given task and writes up a report with citations. It can work from web sources and from local documents, and it works with any LLM provider, aiming for factual, unbiased output rather than a quick chatbot answer.

The project positions itself against several limits of manual and LLM-only research: manual work can take weeks, models trained on old data may hallucinate, token limits make long reports hard, and a narrow source set leads to shallow or wrong conclusions. Drawing on Plan-and-Solve and RAG ideas, it splits research into planning and parallelized agent work to increase speed and keep behavior stable. Customization options let you tailor domain-specific research agents, and topics note MCP server support.

GPT Researcher is written in Python and Apache-2.0 licensed, with documentation in several languages and a website at gptr.dev. You run it yourself with your own model API keys, and it suits analysts, students and developers who want automated, source-backed reports on a topic.

Scira, formerly called MiniPerplx, is a minimalistic AI search tool that finds information online and cites where it came from. The project describes it as an agentic research platform that plans, retrieves and cites, and it is available as a hosted site at scira.ai.

You can start by asking a question, uploading a PDF or pasting a link. Behind it, the README credits the Vercel AI SDK for model integration and streaming, Exa AI for web search and content retrieval, and Upstash for serverless Redis and rate limiting. It is written in TypeScript as a web app you can run yourself with your own provider keys.

Scira is licensed under AGPL-3.0, so modified versions offered over a network must share their source. It suits developers who want a reference AI search app to run or adapt, and individuals who want a cited, minimalistic alternative to conventional search.
