PRESSMARK · Sub-Millisecond Vector Document Engine & Interactive Studio

Author: Daniel Hallman
Brand: Pressmark Studio
Architecture: Pure Rust (Tokio + Axum) + Sub-Millisecond Vector Synthesis Engine

Pressmark is an ultra-fast, publication-grade document synthesis engine, real-time interactive design studio, and Model Context Protocol (MCP) / ChatGPT plugin server. Built to replace sluggish legacy document pipelines (Puppeteer/Headless Chrome, Python ReportLab, WeasyPrint), Pressmark compiles crisp, print-ready vector PDFs and high-resolution PNG previews in under 25 milliseconds with zero disk churn and sub-cent unit economics.

Quick start

1. Open Pressmark Studio to design, preview, and download vector PDFs in your browser.

2. Connect any MCP client (Claude Code, Cursor, Codex, Grok, Gemini CLI, Hermes) to https://pressmark.dev/mcp (streamable-http), or download the pre-packaged plugin bundles from GitHub Releases.
