nvALT is a lightweight, Mac-only note-taking app with a focus on speed and simplicity, featuring Markdown support and excellent search functionality. In contrast, Gruik is a cross-platform app offering rich text editing, collaboration tools, and mobile compatibility, making it more versatile but potentially overwhelming for some users.
