CiteFlow
Desktop research workspace for PDFs, notes, citations, bibliographies.
...Import PDFs, read them inside the app, search within documents, compare files side by side, highlight key passages, and add page-based notes. CiteFlow can assist with DOI metadata detection, keeps citation history linked to copied text, and generates citations and bibliographies in APA 7 and MLA 9.
OCR support helps make scanned PDFs searchable, while project-wide search helps you find matching text across PDFs, highlights, and notes. Supported interface languages include English, Turkish, Chinese, Spanish, German, French, Russian, and Japanese.
