01 / Space to write
Leave the menus behind.
Slim paper mode hides the tabs and panels. For longer sessions, focus mode dims the surrounding text and typewriter mode keeps your current line centred.

02 / Formatting and export
See what you’re writing.
Live view formats headings, lists and emphasis as you type. When you’re ready to share a draft, export it as a PDF, HTML page or Word document.
Easy on the eyes.
Choose light or dark, adjust the text size and pick a document theme that suits what you’re working on.
Find your way around.
Keep drafts in folders you already use. Quick Open finds files by name; the outline takes you straight to a heading.

Add a table, a footnote or an equation. PrivMark also renders Mermaid diagrams and Markdown slide decks.

Do I need to know Markdown?
A few basics help: # Heading makes a heading, *text* adds italics and - item starts a list. Live view shows the formatting as you type. Switch to Source or Split whenever you want to see the markup.
Does PrivMark work offline?
Yes. You can write, edit and export without an internet connection. Automatic update checks can be turned off in Settings → Updates. Pro licences are checked on your computer and don’t need an activation server.
What do I need for local AI?
Install Ollama on your computer, download a model and open PrivMark’s AI panel. You’ll need Pro or the included 14-day trial. Downloading a model requires internet access; running it locally doesn’t. Speed and memory use depend on your model and computer.
What happens after the Pro trial?
You can keep writing, using themes and exporting documents for free. The AI features need a Pro licence once the trial ends. Pro purchases open soon at a one-time price of $9, covering all PrivMark 1.x releases.
Can I use my existing files and tools?
Yes. Open a Markdown file or a whole folder; there’s nothing to import or convert. PrivMark also has Vim keybindings, a VS Code extension and command-line tools for rendering documents, reading outlines and running Pro AI commands.
Where can I find security updates?
Releases include SHA256 checksums. Windows installers are signed by Wolfberry AB; macOS builds are signed and notarized. If you disable automatic updates, follow the security advisories or release feed. Report a vulnerability to hello@privmark.app; we aim to acknowledge reports within 72 hours. Machine-readable contact details are in security.txt.
