OpenMarkdown 0.10.0

What's new

This release focuses on live editing by the agent.

• Agent can now edit one section at a time — e.g., change a single heading's worth of text and only that section is rewritten, not the whole document.
• Assign agent a task in .md context by writing a - [ ] @agent … line into a file it's watching. It picks up the task automatically.
• When agent writes to a file that is open, the change is applied like a remote edit. The cursor and scroll position stay put, and the page doesn't flicker. You can keep typing in one section while it edits another.

Minors

• Fixed a case where an edit could be lost without warning due to a cross-document sync race
• Left-clicking the menu-bar icon (or choosing Open) now reopens the window.
• The DMG now shows an arrow pointing from OpenMarkdown to the Applications folder.

OpenMarkdown 0.9.0

What's new

Hook it up

• Set as default for .md — one click in Settings makes OpenMarkdown your default Markdown app (and one click reverts it).
• Connect your agent — Settings now hands you a single copy-paste command that installs the OpenMarkdown plugin (skill + MCP wiring) into Claude Code.

Images & links

• Local images render in the live preview — ![](attachments/screenshot.png) just works.
• Paste or drag images in — the image is saved to an attachments/ folder beside your note and linked with a relative path, so notes stay portable.
• Long URLs stay folded — links now collapse into a compact chip instead of exploding into raw markdown the moment your cursor touches them.

Small comforts

• Click anywhere outside the Settings panel to close it.
• The scratch folder (where daily notes live) is now configurable in Settings.
• Update checks re-run when the app regains focus (24-hour throttle), so long-running instances never miss a release.
• Command palette polish: one consistent "Daily note" name, duplicate new-note command removed.

OpenMarkdown 0.7.0

Feather-light. Light-speed. The first public release of OpenMarkdown — a
local-first Markdown editor for macOS, fast enough that you and your agent stay
on the same page.

Download

⬇︎ OpenMarkdown.dmg — universal (Apple Silicon + Intel).

Signed with a Developer ID certificate and notarized by Apple: double-click and it opens — no right-click, no xattr, no Gatekeeper warning. It keeps itself up to date from here on.

What it is

• Local-first. Your notes are plain .md files on your disk — no account, no sync service, no lock-in.
• Fast. Cold-starts in milliseconds; live, source, and reading modes are a keystroke apart.
• Built to work with an agent. OpenMarkdown reveals the Markdown your agent produces and senses what you're looking at — a shared whiteboard, not a black box.
• Terminal-native. openmd file.md opens it straight from your shell.

Requirements

macOS on Apple Silicon or Intel.
