Second Brain Joiner (Android): Merge Obsidian notes to AI in seconds. Now on Android! 🚀

Hi Product Hunt! 👋 I'm Dicon, the indie maker behind Second Brain Joiner. When I decided to bring my iOS app to Android, I realized I didn't just want to port it—I wanted to evolve it. As a heavy Obsidian user myself, I was frustrated. Throwing an entire vault at ChatGPT or Claude just leads to hallucinations and broken context limits. I personally needed precise control over *what* context I sent to the AI. So, I built the exact "Pro" features I desperately wanted for my own workflow: ✨ Precise Token Calculation (OpenAI API standard) ✨ Advanced Filtering (Combine Tags/Dates with AND/OR logic to pinpoint notes) ✨ Auto Chunking (For massive vaults) Everything runs 100% locally on your device. No cloud servers, no privacy risks. I poured my heart into this. My ultimate goal is to deliver this secure, local-first bridge between Obsidian and AI to users across 170+ countries. 🌍 🍎 A quick note for iOS users: Don't worry, I promise to backport all these new Pro features to iOS soon! Also, the "Second Brain Pro Bundle" (Joiner + VaultPress PDF Exporter) is currently available on the App Store to complete your ultimate mobile workflow. I would love to hear your feedback and answer any questions. Happy Linking! 🧠✨
