Librarium

Multi-provider deep research CLI that fans a query out to several search and AI APIs in parallel.

Desktopfreeglobal

Librarium is a command-line research tool that fans a query out to multiple search and AI providers, such as Perplexity, Gemini, and OpenAI, in parallel, combining web search, grounded answers, and durable research jobs into one request. It preserves the collection and access provenance behind each result so a caller can judge what it actually means, rather than treating agreement across sources as proof, and is usable by both people and AI agents.
