Dengram is a Markdown reading notes and knowledge management app that works the Zettelkasten way. You rewrite what you read in your own words, and connect notes, books, and authors with links and a concept map, turning scattered reading into your own knowledge. It’s available on Android.
Zettelkasten is a note-taking method where you write ideas as small notes and link them to build knowledge. In Dengram you jot passing thoughts as fleeting notes, put a book’s key points into literature notes in your own words, and keep your conclusions as permanent notes to reuse later.
Notes are saved as Markdown (.md) files on your device, and the content is never sent off-device. Because they use the standard Markdown format, you can open them later in other Markdown apps, so your writing is never locked into one app.

Search by title or scan the ISBN barcode on the back cover to add a book quickly. You can also capture underlined sentences with your camera to pull them into notes — the text recognition runs on your device.
