LibreOffice: what it's good at

• No subscription, no account, no ads

Obsidian: what it's good at

Obsidian stores your notes as ordinary Markdown files in a folder on your own disk, then layers linking, backlinks, graph views and a large plugin ecosystem on top. Free for personal use, with no lock-in — your notes remain readable in any text editor.

• Plain Markdown files stored locally
• Bidirectional links and graph view
• Large community plugin ecosystem
• Free for personal use

Which should you choose?

Both are free, so the honest answer is that you can install either and decide for yourself — that is the advantage of free software over a paid trial.

Both run on Windows, macOS, Linux. Only Obsidian supports Android, iOS. If open source matters to you, LibreOffice publishes its source code and Obsidian does not.

We deliberately do not publish a star rating for either. We have no way to verify a rating that would be honest at scale, and an invented one would be worse than none — so we give you the facts and let you decide.
