| Stashpad is the evolution of the legal notepad. Bytebase is designed for busy professionals who don’t have time for sophisticated notes methodologies and is the fastest way to create and share notes as they work, without leaving the keyboard. In Bytebase, notes are separated into small, self-contained units called bytes. Users can enter data andpaste in code, text, or whatever they want to save. They can share it with others and create separate notebooks for each project. More important, each note can act as a link to another note, allowing to nest information within other pieces of information. To use it, users can simply paste in code snippets and text into the “No Man’s Land” area and then move it into separate projects later. A feed lets users send notes, called bytes, to co-workers within Bytebase. They can also add large text chunks called BigBytes. They can also make outlines and to-do lists in the app. | Seed / Oct 02, 2023 | ||
