- There are two types of notebooks; Basic and Advanced
- Basic notebooks are multi-page blank canvases that can be filled with writing, doodles, etc.
- Advanced notebooks are single-page and infinite-scroll, with options to insert handwriting or ‘special blocks’ to the page – each block is effectively a separate entity, and they are vertically stacked one on top of another down the page
- If you double-tap handwriting in an Advanced Notebook, it will automatically convert to text
- Special blocks include:
- Drawings (freehand drawing)
- Diagrams (double-tapping hand-drawn shapes, text and arrows straighten the edges, which is useful for flowcharts and diagrams)
- Math Equations (double-tapping a hand-written math equation converts it to proper notation, and it can even solve it!)
- Brushes include a ballpoint pen, fountain pen, calligraphy pen, brush, and highlighter.
- There is a choice of five thicknesses and five shades for each brush
- Stylus pressure is supported for the fountain pen, calligraphy pen, and brush tools – there is no tilt sensitivity
- There is an object eraser (removes whole strokes) and a brush eraser (removes parts of strokes) as well as undo and redo buttons.
- There is a lasso selection tool, however, selections can only be moved (no resize, copy, rotate etc.)
- In Basic notebooks, handwriting selected with the lasso tool can be converted to text (multiple pages cannot be converted in bulk)
- In Advanced notebooks, handwriting can be converted to text with a double-tap.
- Handwriting search is supported (single notebook only)
- There are almost 15 templates to choose from (lined, squared, dotted, to-do list etc.)

About the author
Dan Dutton is passionate about E-ink writing tablets, which bring together the pleasure of writing on paper with the power of digital technology. When he bought his first tablet, he realised that there wasn't a lot of unbiased information available for people that were considering buying an E-ink tablet, and so he built eWritable.
