Polar is a personal knowledge repository for PDF and web content supporting incremental reading and document annotation. Manage and prioritize your reading with progress tracking, flagging, tagging, and more.
Hi PH! This is Jonathan, one of the makers here at Polar along with Kevin
Polar is an integrated reading environment that allows you to build a knowledge base from your reading materials
Polar actually started as a side project, when Kevin was working on a different startup idea and was reading on various new topics a lot. Similarly, my interest comes from doing a PhD in chemistry and always looking for a better way to organize all the research papers and information I would extract from that reading
Polar is a tool that enables you to keep all your reading in one place, prioritize and track reading, annotate, highlight, comment, connect thoughts, and create flashcards from those annotations. Since Polar is cloud-based, you can easily sync all of your reading and annotations across multiple files.
Here are the specifics:
Organize and prioritize your reading
Upload PDFs and EPUBs, and capture web pages with the Polar Chrome extension. Keep all your documents in one place. Manage and prioritize your reading with progress tracking, flagging, tagging, and much more
Read actively
Our integrated document viewer is great for incremental and active reading. Annotate, highlight text and areas, tag annotations, comment, use advanced pagemarks, and create flashcards from highlights
Annotations viewer
Keep all your annotations, highlights, and comments in one place. Our annotation viewer shows you all the information you want to keep in one place. Tag, comment, create flashcards, cross-reference information all in one place
Create and review flashcards
Polar allows you to create flashcards in one click from an annotation. Once created, you can review them directly in Polar using our spaced repetition algorithm. Alternatively, use our Anki integration to sync them to Anki. Polar also enables you to review annotations
Keep track of your reading
With our integrated reading statistics, you can easily track your reading, commit to daily goals, thereby keeping you motivated.
