Use tool ↗About ScienceOS
ScienceOS answers research questions against an index of roughly 230 million papers and returns cited sources rather than unattributed prose. It builds comparison tables and diagrams from what it finds, generates citation networks for exploring a literature, and lets you chat across as many as 4,000 PDFs at once; a project manager view keeps separate lines of work apart. The index is refreshed weekly and covers 800 million full-text snippets and 2.4 billion reference pairs. Data sits on EU servers only, and the vendor states user content is not used for training. Operator is scienceOS UG (haftungsbeschraenkt) in Dresden, Germany.

Pros & cons of ScienceOS
Priced well below the usual academic-AI tier and unusually specific about its corpus - 230M papers, 800M snippets, 2.4B reference pairs, refreshed weekly. EU-only storage and a no-training commitment make it easier to clear with a university's data office than most rivals. The free tier is limited enough that serious use means paying.
Pros
- Answers carry cited sources against a stated 230-million-paper index
- Citation networks make backward and forward reference tracing practical
- Chat spans up to 4,000 PDFs, with 1,000-file bulk import on Team
- EU-only servers and an explicit no-training-on-user-data statement
- Cheapest paid tier is around EUR 7 a month, well under most competitors
Cons
- Figure extraction from PDFs is paywalled - the free tier is text only
- The best model is unlimited only on the Team tier at six seats or more
- No API for integrating results into other workflows
- Euro pricing means dollar buyers absorb exchange-rate movement
Best for
- Literature reviews where citation trails matter
- Researchers who need EU data residency
- Working across a large personal PDF library at once
Not for
- Anyone needing an API to pipe results into other tools
- Fields whose literature is not well covered by indexed journals
Watch out: The Team rate of EUR 6.00 per user only applies from six seats up - smaller groups pay the Angel rate each.
