Notational Velocity
Notational Velocity is a computer program for Mac OS X used for notetaking. It allows users to create notes using solely a computer keyboard and search them using incremental find. Other features include database encryption, basic text formatting, tags and spellcheck. In addition, users can synchronize notes with Simplenote and export to a variety of formats, including plain text, HTML and rich text. It has been recommended along with Simplenote as a solution for taking and syncing notes by both Wired and Lifehacker.
Notational Velocity hasn't seen any development activity since September 2011.
In 2013, Elastic Threads and Brett Terpstra created a fork of Notational Velocity with added functionality called nvALT. nvALT was last updated in 2017.
In 2019, Brett Terpstra and Fletcher Penney started working on a replacement for nvALT called nvUltra. As of 2023, nvUltra is available as a closed Beta release.
