Lit Mind Maps vs The Lens

Lit Mind Maps is a web tool for Masters and PhD students conducting literature searches and evidence mapping. Users enter a research question in plain language or provide a paper title or DOI. The service returns cited answers based on retrieved academic papers, then places those papers in a three-branch literature mind map and idea timeline. Branch sets can be changed before another search. A citation map displays a seed paper, its references and citing papers as bubbles arranged by year and citation count. Five optional answer sets address definition, mechanism, evidence, effects and comparison, with three branches each. After signing in and searching, users can download a Word starting draft for a literature review or proposal. Records come from Semantic Scholar. Searches use titles, abstracts and metadata rather than every paper’s full text. The service describes results as a starting aid and advises checking papers.

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.
