Org-mode vs Logseq

Org-mode is characterized by a flexible and versatile system with adaptability to different workflows, making it comparable as an Evernote alternative. It is at once simple and complex., which helps it to compete as an Evernote alternative.

Org-mode has some built-in agenda functionality. You can schedule tasks and assign various degrees of importance to each of them. Org-mode agenda can also be synced with Google Calendar.

Org files are plain text, and lend themselves well to version control. Emacs also has good integrations for various VCS.

Notes and to-dos can be synced with Trello, Toodledo, Simplenote, Orgmobile, or with tools like Git on Github, Dropbox, Google Drive, and Bitbucket, while WebDAV (with iOS and Android) can also be exported to PDF, mind map, LaTeX, HTML, Docbook, or txt.

Org-mode has some basic spreadsheet functionality. Other than auto-formatting ASCII tables (a notoriously annoying problem), it also has support for LISP-like syntax to define equations or any other functionality that can be achieved through spreadsheets.

Org-mode has out-of-the-box support for Latex: it can immediately parse equations (or other Latex markup) and can even compile notes to PDF or HTML.

Logseq is a privacy-first tool for thought.

Similar to Roam's technique of letting the notes flow with links to each other.

The daily journal feature allows you to quickly capture disparate topics under today's date and by way of tags make things organized and findable from any topic page.

Logseq is opensource.

Lots of apps are too graphically flexible in how they allow content to be entered, placed, and formatted. They act like Word when what you want when authoring content is Markdown. Content and semantic structure, not graphical frills.

Logseq support Emacs Org syntax out of the box.
