SeqLog is a native macOS outliner for people who want their notes to stay ordinary files.
Every note is a plain Markdown file in a folder you choose. There is no database and no proprietary format, so ripgrep, git, or any other tool on the machine reads exactly the same bytes. Full text search runs over the folder itself, so there is no index to rebuild or corrupt.
A daily journal and named pages sit side by side. Wikilinks connect them and every page lists the blocks that link to it. A command palette searches page names and file contents together.
Git is embedded rather than shelled out. Edits are committed in the background, the history panel expands each commit into an inline diff, and any single file can be reverted on its own.
It opens an existing Logseq vault in place, because it uses the same journals/ and pages/ folder layout. Nothing to import, nothing to convert.
Written in Swift on AppKit rather than Electron. Free for macOS.
