Divan

A writing room for one Markdown file. Live preview ghosts the markers; the file on disk stays Markdown.

Version 0.6.0 · macOS 26 or later · Apple Silicon. Signed and notarized by Apple. All releases and changelog.

Book paper. Warm page, ink, a serif for headings. Dark is cream on ink.
Three themes. Divan, Sedef, Mermer — paper, pearl, marble. Each in light and dark.
Live preview. Markers tuck away as the caret leaves and come back when you edit. Not a second pane.
Folder panel. ⌘J lists the Markdown beside what you are writing — still one file at a time, this is just how you reach the next one. Read-only: it never renames or deletes anything.
Writing Tools. Proofread, rewrite, summarize. Apple's, from Edit.
No telemetry. No analytics, no crash reporting, no accounts. What you write never leaves your Mac. The one thing Divan can be asked to do over the network is ask GitHub whether a newer version exists — off until you turn it on, and it never installs anything.

Tables. GFM pipes on disk. Lined up on the page.
Callouts. > [!note] and > [!warning] — still a blockquote.
Decisions. **Decision:** and the rest of the line is the call.
Image drop. Saved files take a drop into ./assets/. Unsaved files ask you to save first.
Your measure. Mono, serif or sans, and a column you drag to whatever width reads best.
Export. HTML that carries the same type and colour, and PDF through Print.
