Standard markdown, plus math, diagrams, and syntax-highlighted code.
PrivMark supports bold, italic, strikethrough, inline code, and links.
Every heading level renders with the right visual weight, and lists nest cleanly:

function hello(name) {
return `Hello, ${name}!`;
}Your documents are yours. PrivMark never sends your text anywhere.
LaTeX math rendered via KaTeX, and flow diagrams rendered via Mermaid — both live in the app:
E = mc² · ∫₀∞ e−x² dx = √π ⁄ 2 · Σi=1n i = n(n+1)/2
(math and diagrams are interactive and render in real time inside the editor)
Built by Wolfberry AB, a security-focused Swedish software company.

Machine-readable: /.well-known/security.txt follows RFC 9116.
Runs entirely on your machine via Ollama. No cloud, no account, no API keys. Your writing never leaves your computer.
