Kami - an open-source AI document design system that outputs deliverable, professional documents. - AiBoss

What is Kami?

Kami is an open-source AI document design system developed by tw93 and distributed as a Claude Code Skill. It specifically addresses the problem of monotonous layouts and cheap visuals in AI-generated documents. The tool uses a strict set of print-compliant rules, including a warm beige canvas, a single ink blue accent color, a fixed-weight serif font, and tight line spacing, to ensure stable, deliverable professional-looking PDFs. Kami supports eight document types: single-page reports, long documents, letters, portfolios, resumes, slides, financial statements, and update logs, as well as 14 types of embedded SVG charts. It is also compatible with Chinese, English, and Japanese.

Kami's main functions

8 document templates: One-Pager (single-page report), Long Doc (white paper/research report), Letter (formal letter), Portfolio (project portfolio), Resume (resume), Slides (presentation slides), Equity Report (financial statement analysis), Changelog (update log).
14 types of embedded SVG chartsArchitecture diagrams, flowcharts, Gantt charts, etc., can be directly injected into AI without the need for external images.
Trilingual typesettingEnglish and Chinese are considered first-class citizens; Japanese will be supported as much as possible through the CJK channel, but visual QA is required before delivery.
Brand Configuration:support ~/.config/kami/brand.md Persist in personal brand colors, identity, writing habits, etc.

Kami's technical principles

Constraint-driven designThe tool is a set of hard rules across documents (eight ironclad rules including canvas color, accent color, grayscale, font, font weight, line spacing, shadow, and tag background). The AI is constrained by the same set of rules every time it outputs, thus avoiding style drift.
Skill distributionIt exists in the form of Claude Code / Codex / Claude Desktop Skill, and the AI is automatically triggered by natural language requests, without the need for slash commands.
WeasyPrint renderingThe backend converts HTML/CSS to PDF; specific workarounds have been implemented to address bugs such as the rgba() double-layer rectangle issue in WeasyPrint.
Font StrategyEach language uses only one serif font (Chinese Cang Er Jin Kai 02, English Charter, Japanese YuMincho), which is loaded locally first, and then uses jsDelivr CDN when missing.

How to use Kami

Installation skillsTo add Kami, open your AI programming tool (such as Claude Code or Codex), search for Kami in the official plugin marketplace, or find the skill management entry in Claude Desktop settings and directly upload the installation package provided by the author; no unzipping is required.
Natural Language Description RequirementsAfter installation, simply tell the AI what document you want; you don't need to remember any commands.
AI-automated design application systemAI will automatically recognize the requirements, call the corresponding template from Kami, and generate a PDF according to rules such as warm beige canvas, ink blue accent color, and professional serif font.
Downloads and UpdatesThe generated document is output directly as a PDF, which can be printed or sent immediately. To update your Kami version, simply download the latest installation package and replace the old version in the skills management page.

Kami's core advantages

Say Goodbye to "Universal Gray"A warm beige canvas replaces pure white, making printing and screen reading more comfortable and professional.
Single accent color restraintUse only ink blue, accounting for no more than 5%, to create a clear and unpretentious visual focus.
No bold designUse a fixed font weight and establish hierarchy by using font size and the left vertical line to avoid the cheap feel of arbitrary bolding.
Printing line spacingThe title should be concise, the body text densely packed, and the line spacing appropriate, avoiding a loose or sloppy webpage feel.
Agent friendlyThe rules are so simple that AI can execute them reliably, and so strict that every output can be delivered directly.
Lightweight updateThe installation package is extremely small; simply upload and replace to update.
