From checkout to activated in three steps.
Dodo Payments handles checkout and tax. PeekMark verifies the license through the Quartz activation gateway.
Buy Pro
Complete the secure Dodo Payments checkout. Your license is a one-time purchase, not a subscription.
Copy your key
After payment, copy the license key from the confirmation page or your receipt email. Keep it private.
Activate on Mac
Open PeekMark → Settings → General, paste the key, and choose Activate. Repeat on up to three personal Macs.
Your notes stay yours.
Payment and license verification require network access. Markdown rendering, workspace indexing, search, backlinks, and graph analysis stay on your Mac.
No content upload
Preview content is rendered locally rather than sent to a hosted Markdown service.
No cloud index
Workspace search and relationship data are built from local files on your Mac.
Only what activation needs
License requests use the key and an app-scoped one-way device identifier, not your document contents.
Questions, answered plainly.
The renderer is free and open source. Pro adds a paid workflow around the Markdown files you already own.
What is PeekMark?
PeekMark is a native Markdown previewer and local-first workspace for Mac. Community adds Finder Quick Look and rich local rendering; Pro adds workspaces, advanced search, backlinks, a knowledge graph, themes, and export.
How do I preview a Markdown file on Mac?
Install PeekMark Community, select a Markdown file in Finder, and press Space. Quick Look renders GFM, code, Mermaid, Math/LaTeX, frontmatter, tables of contents, anchors, and wikilinks locally.
Is PeekMark a Markdown editor?
PeekMark is a Markdown viewer, previewer, and workspace rather than a full text editor. It renders and connects the Markdown files you already own.
Does it upload my Markdown?
No. Rendering, workspace indexing, search, backlinks, and graph analysis run on your Mac. Network access is used for downloading the app, checkout, and Pro license verification.
What stays free?
Finder Quick Look, GitHub Flavored Markdown, syntax highlighting, Mermaid, Math/LaTeX, frontmatter, tables of contents, anchors, and wikilinks remain in Community under AGPL-3.0.
How does the Pro license work?
PeekMark Pro is a one-time $12.99 purchase for activation on up to three personal Macs. There is no recurring subscription.
Can I move a Pro purchase between the App Store and the direct edition?
App Store purchases and direct Quartz licenses are separate entitlements. Restore an App Store purchase with the same Apple Account, or reactivate a direct purchase with its Quartz license key; purchases do not automatically convert between channels.
