All markdown notes are saved automatically as you write and various formatting options have semi-live previews so you can double check what you’re writing. Also, the text is formatted as you type. It's easy to sync all notes and code snippets via Dropbox, GoogleDrive or any other file-based cloud services. Just put your storage to your local folder for syncing. Created notes can be easily saved as plain text or markdown files.
Boostnote displays also the number of words and letters in documents, modification date, and an option to print the document. Most of the popular functions can be accessed using useful shortcuts. Moreover, you can customize the user interface by selecting Overall, Editor and Code block theme you like. Also TeX is supported to display math formulas. The software is available for Linux, Windows, and Mac.
