Convert GoodNotes archives to SVG, PDF, and JSON formats using 100% local processing.

Hi HN, I'm the author of this project. I built this because I wanted my handwritten notes to truly belong to me—free to be migrated to other apps instead of being locked inside the proprietary Goodnotes ecosystem. To be honest, I have absolutely no background in reverse engineering or binary file parsing. I built this almost entirely through "vibe coding" (using LLMs as my pair programmers—mainly Gemini Pro/Flash, and occasionally Claude Sonnet). My ultimate goal is to unlock .goodnotes files so

做了一个 MP4 转文字的小工具 最近自己做了一个 MP4 转文字的 AI 小工具,主要用于把视频快速转换成文本。 项目地址: https://mp4totext.ai/ 开发过程中发现,真正麻烦的并不是调用语音识别模型,而是视频格式兼容、音频提取、长视频处理以及异步任务这些细节。 目前还在持续优化,如果大家平时有视频转文字的需求,欢迎试试看。 也想听听大家对视频转写类工具还有哪些实际需求。

Jokes aside but honestly (Landing page) was built with Claude (Opus 4.7) in 1 day. But no, it was not just four prompts or some random skills. Here's how I built the entire AsciiMagic landing page with Claude in one day👇 Started with a rough sketched wireframe. Then designed it in @paper Then I used the Paper MCP with Claude to recreate that design in code and get a solid first version running. From there, the real work began. I kept iterating with specialised Claude skills: • impeccable • frontend-design • emil-design-eng • review-animations • responsive-design • seo-audit Each one improved a different part of the experience. By the end, the page had: • Mobile-first responsiveness • Better SEO optimised copy • Smooth micro-interactions • Cleaner frontend architecture Then came the part people don't see. For the next 5–6 hours, I wasn't asking Claude to "make it prettier." I was: • Fine-tuning layouts • Uploading and compressing assets • Moving files across diff
