Jimmy is a tool to convert your notes from different formats to Markdown

Jimmy is an open-source command-line tool that converts notes from various proprietary or non-standard formats (like Apple Notes, Microsoft OneNote, Evernote, or wikis) into Markdown, a lightweight plain-text markup language. Markdown is widely used in software development, static-site generators (e.g., Jekyll, Hugo), and note-taking apps (Obsidian, Logseq) because it is human-readable, future-proof, and easy to version-control. The tool solves the data-portability problem: users locked into a specific note-taking platform can migrate their notes to an open format without manual copy-pasting. It is authored by an individual developer (marph91) and hosted on GitHub.
