ResearchRabbit is a web service for discovering research related to papers users select. It analyzes those papers and recommends connected work, with interactive maps showing links among papers, authors and concepts. Its recommendations adapt to reading patterns and research interests. The Free plan costs nothing and provides unlimited searches across more than 310 million articles, an unlimited library and collections, sharing, core search settings and up to 50 seed articles. ResearchRabbit+ raises the seed limit to 300 and adds advanced search controls, multiple projects, Signals alerts and faster support responses. Its annual plan costs $10 a year (billed per month, Annual plan); the monthly plan costs $12.50 a month (billed per month, Monthly plan). Users can import selected articles from Zotero collections and export articles as BibTeX. ResearchRabbit is aimed at researchers and students, and does not provide screening workflows, full-text management or systematic review tools.

The Lens connects scholarly literature and patent records for discovery, analysis, decision-making, and partnering. Patent search offers Boolean, structured, biological, and classification queries, alongside filters and sorting. The Lens says its scholarly collection contains more than 200 million records and links scholarly works to patents through citations. PatSeq tools search, analyze, and share biological sequences disclosed in patents. Search results can be visualized in charts and dashboards, which users may save and share. Registered users can save collections and queries, add notes, and receive notifications when new indexed results match them. Lens Profiles combine author and inventor records and support ORCID linking and synchronization. Anonymous browsing is free, as is a non-commercial academic workspace for users with an academic institutional email. Individual commercial users need commercial-use permissions through a subscription or institution. The Individual Professional Workspace costs $1,000 a year. APIs support programmatic search and retrieval, subject to approved access and a token.
