I also happen to be a massive Obsidian user with a highly complex vault. </p> <p>Recently, I wanted to leverage AI to analyze my notes, but I hit a wall: <strong>I didn't want to upload my entire personal vault to the cloud, and preparing the exact context for AI was a nightmare.</strong> Also, exporting complex Markdown to beautiful PDFs was always broken.</p> <p>So, I decided to build my own solution.<br> 　<br> 　</p> <h2> 🛠️ The Solution: A Local-First Input/Output Suite </h2> <p>I built two local-first apps to solve the input/output problems for Obsidian power users.<br> 　</p> <h3> 1. Second Brain Joiner (SBJ) - The Input Engine </h3> <p>SBJ allows you to merge, and copy your specific Obsidian notes perfectly formatted for AI context. All processing is done <strong>locally</strong> on your device. No cloud risks.</p> <p><a href="https://youtube.com/shorts/YVI3L7hTjpA" rel="noopener noreferrer">Second Brain Joiner-Demo</a><br> <iframe src="https://www.youtube.com/embed/YVI3L7hTjpA"> </iframe> 　<br> 　</p> <h3> 2. VaultPress (VP) - The Output Engine </h3> <p>What about output? I built VaultPress, a powerful local rendering engine that turns your complex Markdown notes into flawless PDFs instantly. Beautiful input deserves beautiful output.</p> <p><a href="https://youtube.com/shorts/vFAoHL3SlrA" rel="noopener noreferrer">VaultPress-Demo</a><br> <iframe src="https://www.youtube.com/embed/vFAoHL3SlrA"> </iframe> <br> 　　<br> 　</p> <h2> 🚫 The Best Part: No Subscriptions </h2> <p>I hate monthly fees as much as you do. <br> As an indie dev, I want to provide tools that you truly own. Both a</p> <p>pps are <strong>one-time purchases</strong>. Buy once, use forever.<br> 　<br> 　</p> <p>🍏 <strong>For iOS Users:</strong><br> The complete Input/Output suite is available NOW on the App Store as an App Bundle!<br> 　<br> <a href="https://apps.apple.com/us/app-bundle/second-brain-pro-bundle/id1887592238" rel="noopener noreferrer"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F6ilt79dr3besj2743ibo.png" alt="logo" width="150" height="50"></a></p> <p>　<br> 🤖 <strong>For Android Users:</strong><br> Get ready! SBJ (with massive new features) and VP are currently in review. I will announce the release very soon!</p> <p>I’d love to hear your thoughts and feedback. How do you currently handle exporting and feeding your Obsidian notes to AI? Let me know in the comments! </p> <p>Cheers from Japan! 🇯🇵</p> showcase obsidian productivity ai
