R Discovery
R Discovery is a research reading and literature search app from Cactus Communications, covering 150M+ journal articles, 78M+ open access papers and 10M+ conference documents. It offers AI summaries with citations, chat with a PDF, generated literature reviews, audio papers and translation into 30+ languages.
- Retrieval from an indexed corpus removes the invented-citation failure entirely
- 78M+ open access papers means citations you can actually read
- Chat with a PDF is genuinely useful and carries almost no risk
- Audio and translation address access rather than merely convenience
- A generated literature review is a map of a field, not an argument about it
- Retrieval bias produces invisible gaps where the corpus is incomplete
- Relevance ranking systematically buries foundational work and negative results
Clarivate's Web of Science Research Assistant is a generative and agentic AI layer over the Web of Science Core Collection, turning a research question into guided literature-review, author and trend workflows with visible grounding in trusted data.
- Grounded in a curated, publisher-independent citation database rather than the open web
- Agentic, guided workflows add real structure to literature review
- Visualizations surface connections a prose summary cannot
- Clear responsible-AI commitments developed with researchers and librarians
- Access is institutional, so you cannot simply sign up as an individual
- Curated coverage omits the long tail, preprints and unindexed work by design
- The extended feature set depends on which Web of Science products you license
