Markanm
PDF annotations: what is available now.
Markanm currently supports text masking for recall. Broader highlighting and annotation tools are planned, but are not available yet.
Available now: text masks
Select PDF text to hide it, make a recall attempt, and reveal the original.
Planned annotation tools
Highlight colours, underlines, notes, freehand ink, and shapes are not built yet. This page will change when those tools are ready.
Keep your study routine focused
Use masks to revisit ideas already present in your PDF without suggesting that unsupported annotation types are available.
