What it does
Sumnotes consolidates annotations from PDFs, Kindle, Instapaper, and webpages. Its tools organize highlights with search, tags, and editing, then export them to reusable formats.
Collect existing PDF and Kindle highlights into a searchable library, then use tags and colour changes to group material for a paper or revision session. Export only the organised annotations when a Word document, spreadsheet or plain-text outline is more useful than the full source PDF. The published Pro subscription includes Anki flashcards, unlimited annotations and 5 GB of document storage. Word, Excel, TXT, clipboard, email and Evernote are listed export routes.
