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

I built a PDF redactor that auto-detects names, SSNs, and account numbers without sending your file anywhere - works on your phone too. Free, no sign-up. Plenty of redaction tools upload your file to their server first (no thanks for legal/medical/tax docs). Some keep the file local but send the text off to an AI, so the text still leaves. And most of the truly local ones only let you draw black boxes by hand, which is how those "redacted" documents in the news keep getting un-r
