What is logically?

Its official positioning is to help users conduct citation-supported research, manage reference documents, write literature reviews, annotate PDFs and write papers. Its core is to integrate writing, citation and data management: when using AI to continue writing in a document, relevant citations will be automatically attached, and reference documents are also organized in the same place. Different from pure writing tools, Logically emphasizes that "every conclusion can be traced back to the source" and is equipped with a literature manager and a PDF annotator. The official claims that it has more than 100,000 users from top institutions.
