Early alpha · open source

Markdown, exactly as you wrote it.

A local-first Markdown editor that edits visually — no preview pane, no split screen — while never rewriting a byte you didn't type. Your files stay yours, on your disk, in plain text.

01

Pages in a sidebar

A collapsible sidebar holds every page in the vault. Files stay files — folders on disk, nothing hidden in a database.

02

Formatting that gets out of the way

Bold, italic, headings, paragraphs, bulleted and numbered lists — applied inline, the way you'd expect, with the Markdown source intact underneath.

03· In progress

Mermaid diagrams

Diagram rendering is being built. Mermaid blocks are preserved verbatim today, but they aren't drawn in the editor yet.

v0.6.1Active AlphaSeptember 12, 2026

Paste-as-Markdown, Safer Tab Close & Smarter Untitled Numbering

A hardening patch release fixing workspace lifecycle papercuts: rich-text paste converts cleanly to Markdown, image pastes upload with instant placeholders, closing tabs never trashes vault files, and Untitled / New Folder counters recycle after Trash.

Release

Official v0.6.1 Release

Patch release packaging paste-as-Markdown, placeholder image uploads, and workspace tab / watcher / numbering fixes.

Feature

Paste-as-Markdown with placeholder image uploads

Pasting rich text or HTML now converts to clean Markdown on drop-in, and pasted images show an instant placeholder while uploading to the assets/ sidecar in the background.

Fix

Close tab without trashing vault files

Closing an untitled or open tab no longer moves vault files to Trash — tab close only clears editor state while disk files stay untouched until explicitly deleted.

Fix

Hash-only watcher echo & vault sync reset on close

File watcher now ignores hash-only echo events to stop phantom reloads, and vault sync state fully resets on vault close to prevent stale tabs or ghost unsaved dots.

Fix

Reuse Untitled-N and New Folder N after Trash delete

Deleting an Untitled note or New Folder to Trash now frees its number, so the next created file reuses the lowest available Untitled-N / New Folder N instead of counting up forever.

A laser-focused update introducing distraction-free Zen writing, lightning-fast full-text vault search, and massive latency reductions for large documents and math.

Feature

Distraction-free Zen writing mode

Silence all UI chrome, sidebars, and panels with a single shortcut to immerse completely in writing without distractions.

Performance

Instantaneous full-text search across all markdown files in your vault with fuzzy matching and keyword highlights.

Feature

Rapid file creation & inline note renaming

Create new notes instantly from search or shortcuts, and rename active notes seamlessly without breaking links.

Folder Vaults, File Watcher Reconciliation & Draggable Tabs

Release

Official v0.5.0 Release

Milestone release transitioning Manicule to true folder-backed vaults with asset sidecars.

Feature

Reorder document tabs with smooth mouse drag-and-drop or keyboard shortcuts, complete with visual drop indicator and unsaved change status.

Fix

Preserve undo history across mode toggles & debounce auto-rename

Switching between visual hybrid mode and source markdown no longer clears the undo/redo stack. Hardened document outline and subpage links.
