Designed, Not Generated: Why I Built Decklume

说明与用途

Decklume 通过固定画布、网格、排版、预定义布局、主题和 QA 检查，将 AI 生成的演示文稿转化为专业、无错误的幻灯片。

问题

AI‑generated slides often look unprofessional because the model is asked to design with vague adjectives, leading to overflow, unreadable colors, and generic layouts.

结果

Decklume delivers a 33‑slide lecture in all 13 themes with 0 QA errors, producing a 1.1 MB vector PDF and a self‑contained HTML file that runs anywhere.

工作流

• Ask Claude Code for a presentation or convert an existing PPTX
• Decklume asks one round of questions about purpose, audience, and style
• It writes an outline with slide layouts and assertion headlines for approval
• It renders the user’s title and content slides in three themes and lets the user pick or mix them
• It builds each slide as plain HTML with layout classes, speaker notes, and optional animations
• It runs a headless‑browser QA gate checking overflow, overlap, type size, contrast, font load, placeholders, images, and JS errors
• It outputs a self‑contained HTML file, vector PDF, PNGs, or a live link

证据

AI can write a whole presentation in seconds. Then you spend an hour fixing it.

Decklume gives Claude the same system: A fixed 1920×1080 canvas, a type scale and a 12‑column grid, 30 tested layouts, 13 complete themes, and a QA gate.

来源

Errors must reach zero. The fix is always to change the content or the layout, never to hide the problem.

As a test, the 33‑slide demo lecture is built in all 13 themes, and every one passes with 0 errors and 0 warnings.
