In their own words
LitMap
LitMap is a web tool for analyzing papers and organizing a literature review. Users upload PDFs, and the service extracts claims, methods, and findings. AI extraction can also identify definitions and limitations, with editable results. Papers are clustered by semantic similarity on a visual canvas that users can rearrange. LitMap highlights disagreements with side-by-side quotations and lets users mark them resolved or unresolved. Its gap finder identifies missing populations, methods, or timeframes. Users can arrange papers and themes into an outline, then export organized notes with citations as Markdown, CSV, or JSON. LitMap does not write literature-review prose or paraphrase sources. The site says it works offline, keeps data in the browser, and requires no account. It is labeled beta. The Free plan costs nothing and allows five projects with 50 papers per project; Student costs €5 a month, and Academic costs €25 a month.
