Alternatives to Causaly

GPT Researcher is an open-source autonomous research agent. Per the project's own site it takes a question, gathers information from multiple online sources, and returns an organised report with comprehensive cited sources; it supports any LLM (OpenAI, Anthropic, Groq, Llama 3 and Hugging Face are named), any search engine (Google, Bing, Tavily and DuckDuckGo are named), and can be added to a team of agents to collaborate on research. The project states it ranked first on Carnegie Mellon University's DeepResearchGym benchmark of deep research systems over 1,000 complex queries in May 2025 - an independent evaluator, though the benchmark result itself is reported by the project and we have not verified it against the evaluator's own publication. It reports millions of downloads and hundreds of contributors. On assurance the page is silent throughout: no runtime limit on scope, spend or authority, no record of what the agent did, no compliance certification, no insurance, indemnity or outcome-linked payment term is published on the page checked. All five trust-gap dimensions score 0 on this evidence, which is the expected shape for an open-source project distributed without warranty.
