markKeep is a free Chrome extension designed to enhance the functionality of Google Keep by incorporating a live Markdown editor. This tool allows users to format their notes using Markdown with a real-time preview, eliminating the need to switch between editing and preview modes. The extension is lightweight at only 15KB, ensuring it does not consume significant system resources. Additionally, markKeep operates without tracking or ads, and it features a dark mode for user convenience.

Among its notable features, markKeep enables users to clip web content in Markdown format using the Keep clipper. However, it is important to note that the Keep labels feature does not function while using the live Markdown editor. For those looking for a streamlined note-taking experience, markKeep provides a practical solution for managing notes in Google Keep.
