Users can enable plugins independently to add Mermaid diagrams, KaTeX equations, and Prism-based code highlighting directly in documents, with clean export to PDF, DOCX, or HTML.", "body_md": "Most document tools force a choice: write in a simple editor and lose advanced features, or use a complex tool and spend half your time fighting it.\n\nPaperQuire's plugin system gives you a third option. Start simple, add capabilities when you need them, and everything renders cleanly in your exported PDFs.\n\nPlugins extend what PaperQuire can render from Markdown. Without plugins, you get standard Markdown — headings, lists, tables, links, images, code blocks. With plugins, you get:\n\nEach plugin activates independently. Enable what you need, leave the rest off.\n\nThis is the plugin that changes workflows. Instead of drawing diagrams in a separate tool, exporting PNGs, and embedding them (and then re-doing all of that when something changes), you write the diagram in your Markdown:\n\nmermaid\ngraph LR\n    A[Write Markdown] --> B[PaperQuire]\n    B --> C[Professional PDF]\n    B --> D[Branded DOCX]\n    B --> E[Clean HTML]\nPaperQuire renders this as a crisp vector diagram directly in your document. When you update the diagram, you edit text — not an image file.\n\nThis works for architecture docs, process flows, project timelines, database schemas, and anything else you'd normally draw in Lucidchart or draw.io.\n\n**Supported diagram types:**\n\nAll rendered locally. No external service, no API call, no internet required.\n\nIf you write technical or academic documents, you've probably wrestled with equation rendering. KaTeX gives you LaTeX-quality math without the LaTeX toolchain:\n\nInline math with single dollar signs: `$E = mc^2$`\n\nBlock equations with double dollar signs:\n\n```\n$$\n\\int_{-\\infty}^{\\infty} e^{-x^2} dx = \\sqrt{\\pi}\n$$\n```\n\nThis renders beautifully in both the preview and the exported PDF. No separate compilation step, no missing fonts, no \"why is this equation a blurry image.\"\n\nThe syntax highlighting plugin uses Prism to color-code your code blocks. Specify the language after the opening backticks:\n\npython\ndef fibonacci(n):\n    if n <= 1:\n        return n\n    return fibonacci(n - 1) + fibonacci(n - 2)\nThis renders with proper color-coded syntax in your PDF — keywords, strings, comments, and functions all visually distinct. It supports 190+ languages out of the box.\n\nFor technical documentation and engineering specs, this is the difference between \"readable\" and \"I'll just look at the repo.\"\n\nOpen PaperQuire, go to **Settings > Plugins**, and toggle on what you need. That's it. No package manager, no config files, no restart required.\n\nPlugins activate immediately in the editor preview and in all future exports.\n\nHere's where it comes together. Say you're writing a technical architecture document:\n\nOne file. One tool. One export. The output is a document that looks like it took a team of technical writers and a graphic designer to produce.\n\nPaperQuire's plugin API is open and documented. If the built-in plugins don't cover your use case, you can build your own:\n\nThe [plugin documentation](https://paperquire.com/docs/plugins.html) has examples and a starter template. If you've written a markdown-it plugin before, you already know how it works.\n\nAll built-in plugins are included on every plan.
