"... an app that students, academics, and anyone who does substantial amounts of PDF-based research should try" -

Highlights is a fast and lightweight PDF reader (under 10MB) packed with features to help with your research.

Free users have access to standard PDF reader features including document browsing, reading and annotating. There are NO ADS, time limits or tracking.

Context aware annotation popovers gives you powerful tools at your finger tips. Default annotation colors prevents you from having to repeatedly setting the color for the same type of annotation every time.

As you markup text and images the contents are extracted and sorted into notes. You can customize the formatting further and sort the annotations chronologically using your own color coding.

Convert images containing text or tables to actual text and tables using machine learning - letting you get to the underlying data with a single tap.

Copy annotations to the desired format — text markup as text and image selections as images, but tables as CSV and citations as BibTex.

Markup any reference and tap the link icon to look it up. Highlights will fetch DOI-links and even check if you have read the work already or have it in your reference manager library.

Export your notes as files (Markdown, HTML, TextBundle or PDF files) or open them directly in your favorite shoebox application (including Ulysses, Evernote, Bear, DEVONThink, Keep It, and Apple Notes).

• Dark mode
• Multi-window support on iPadOS
• Keyboard shortcuts and navigation
• Support for system Copy and Undo gestures
• Custom accent colors
• Apple Pencil double-tap gestures

Prometedor, pero

Le daría 5 estrellas si se pudiera anotar en markdown como se hacía en la anterior aplicación. Utilizo esta app junto con zotero para investigación.
