scienceOS
scienceOS helps scientists search, read, and organize literature through three connected tools: an AI science chat grounded in published papers, a multi-PDF chat for your own library, and project workspaces for team collaboration. Ask a research question and answers pull from an index of more than 230 million papers sourced from Semantic Scholar, with weekly database refreshes. Upload PDFs to extract data from text, tables, and figures, then draft manuscript sections tied to those sources.
Most general chatbots answer from training data with no paper trail. scienceOS grounds science chat in 800 million full-text snippets and 2.4 billion reference pairs, and stores chats, uploads, and account data on EU servers under GDPR controls. The trade-off is scope: it is built for academic literature workflows, not casual conversation, and the best models sit behind the paid Angel plan at 7.25 euros per month.
Researchers at universities including ETH Zurich, Cambridge, and TUM use scienceOS for literature reviews, citation network mapping, and shared project libraries. Free accounts access the fast model with daily limits, while Angel subscribers unlock deep research mode, PDF+ figure extraction, and bulk imports of up to 100 files. Team and institution plans add longer PDF limits up to 1,024 pages and shared billing for labs.
