Etonym in the dark theme. The side panel shows a folder tree of notes, and the editor shows launch-plan.md with a checklist, a milestones table and links formatted in place.

Live preview

Formatted as you write

Headings, checkboxes, tables and links appear formatted while you type. The line with the cursor shows its Markdown, so you always see what is in the file.

How the editor works

launch-plan.md in the editor. The line with the cursor shows its raw Markdown link and bold markers; the other lines show formatted checkboxes, a table and links.

Tables

Edit tables cell by cell

Type in any cell, select a range, and copy or paste to and from a spreadsheet. The file keeps a plain Markdown table.

Working with tables

A milestones table in launch-plan.md with the Due and Status columns selected, and table tools for rows, columns and alignment in the toolbar.

Mermaid diagrams

Diagrams from plain text

Write a Mermaid block and the note shows the diagram. It renders offline, and the file keeps only the text.

Writing diagrams

An architecture note with a Mermaid flowchart rendered as a diagram, followed by an embedded image.

Find any note in the folder

Search the text of every note at once and see each match in context. To jump to a note by name, press Ctrl+O.

Finding notes

Search results for "launch" across five notes, with matches highlighted and launch-plan.md open in the editor.

Git

Commit without leaving your notes

See what changed, read the diff, pick the files, then commit and push. If a pull stops on a conflict, keep your version, theirs or both, part by part.

Committing and pushing

The Git tab with a commit message, three changed files marked M and A, Commit and Commit & Push buttons, and the diff of launch-plan.md in the editor.

Note history

Every version of a note

See each version of a note that Git has kept, who wrote it and what changed. Restore any version, and undo the restore in the editor.

Reading a note's history

Note history beside launch-plan.md, listing five versions with dates and authors. One version shows its added lines, with a Restore this version button.

Questions

Is Etonym free?

Yes. Download it and use it without an account.

Where are my notes stored?

In a folder you choose, as plain Markdown files. Open them in any editor, or move the folder wherever you like.

Do I need to know Git?

No. Etonym writes and saves notes without Git. To keep versions and sync, it uses the Git on your PC, and the Git tab handles commit, push and pull. Your SSH keys, hooks and commit signing work as they do in the terminal. How Etonym uses Git

Why does Windows warn me when I install it?

Etonym is not code-signed yet, so Windows SmartScreen warns about new apps. Select More info, then Run anyway. You can check the file against its SHA-256 first. Check the file

Is there a macOS version?

No. Etonym is for Windows 10 and 11 (64-bit) only.
