A GNU Emacs major mode for keeping notes, managing to-do lists, planning projects, and authoring documents in plain text. Files are stored locally on Windows, Mac, and Linux; no account or cloud dependency required.

Our take
Org-mode is the power-user ceiling in this category: your notes are plain text files you own entirely, you can encrypt individual entries or whole files with GPG, version-control everything with git, and never touch a server you do not control. The honest catch is that it requires Emacs, which has a steep learning curve, and the full feature set is not available outside of Emacs despite third-party tools for mobile and other editors. For technically inclined users who want maximum note sovereignty, nothing else comes close.
