I built a local-first Obsidian suite to safely feed my vault to AI 🛠️🐕

Hi everyone! 👋 I’m Dicon, a Hospital IT Architect and Indie Dev from Japan.
And this is my chief assistant/QA tester, Maru the Shiba.🐕🌸

Working in medical IT, I know how critical data privacy is. I also happen to be a massive Obsidian user with a highly complex vault.

Recently, I wanted to leverage AI to analyze my notes, but I hit a wall: I didn't want to upload my entire personal vault to the cloud, and preparing the exact context for AI was a nightmare. Also, exporting complex Markdown to beautiful PDFs was always broken.

So, I decided to build my own solution.
　
　

🛠️ The Solution: A Local-First Input/Output Suite

I built two local-first apps to solve the input/output problems for Obsidian power users.
　

1. Second Brain Joiner (SBJ) - The Input Engine

SBJ allows you to merge, and copy your specific Obsidian notes perfectly formatted for AI context. All processing is done locally on your device. No cloud risks.

2. VaultPress (VP) - The Output Engine

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.

🚫 The Best Part: No Subscriptions

I hate monthly fees as much as you do.
As an indie dev, I want to provide tools that you truly own. Both a

pps are one-time purchases. Buy once, use forever.
　
　

🍏 For iOS Users:
The complete Input/Output suite is available NOW on the App Store as an App Bundle!
　

　
🤖 For Android Users:
Get ready! SBJ (with massive new features) and VP are currently in review. I will announce the release very soon!

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!

Cheers from Japan! 🇯🇵
