SuperBrain is your self-hosted, AI-powered second brain for Android. Stop losing content in siloed watch-later lists. Share any URL from IG, YouTube, or the web SuperBrain automatically analyzes, summarizes, and tags it in seconds. Features include native YouTube understanding, music ID from reels, and audio transcription. Everything is stored in a local SQLite database YOU own. No subscriptions, no data harvesting. Just smart discovery and organization on your own terms.

I’m the creator of SuperBrain, and I’m incredibly excited to share this with you all today. We all save content constantly Instagram reels, YouTube tutorials, recipes, and deep-dive articles. But the reality is that most of it ends up in a "digital graveyard." We save things and never look at them again because they're buried in siloed apps with no search, no context, and no reminders. I built SuperBrain because I wanted a unified, intelligent inbox for my digital life one that I actually owned. No cloud subscriptions, no data harvesting just my own AI-powered second brain. What makes SuperBrain different? 🧠 Intelligent Analysis: It doesn't just store a link. It watches the video, scrapes the page, and listens to the audio (via Groq/Whisper) to give you a perfect summary, tags, and even identifies background music. 🏠 Self-Hosted & Private: Your data is stored in a local SQLite database that you own. It’s "AI you can trust." 🤖 Smart AI Routing: The backend automatically load-balances between Groq (for speed), Gemini (for depth), and local Ollama models to ensure you always get the fastest results. 📱 Native Integration: Share anything from your Android share sheet directly into your brain.

Self-hosted AI second brain on Android — what's the storage model? Does SuperBrain sync across devices or does it stay purely local to the phone? And does it support open-source LLMs running on-device, or does it require an external API key?

@jimmypk Great question let me clarify the architecture a bit more clearly.

SuperBrain works with a companion backend that you host yourself. The Android app acts as the interface whenever you share content (links, videos, etc.), it sends it to your backend server, which processes everything (summaries, embeddings, tagging, etc.) and then serves it back to your app.

So your data isn’t locked anywhere you can run the backend:

  • Locally on your laptop

  • On a VPS

  • Or any server you control

AI Models:
You’re not restricted here either. SuperBrain supports:

  • External APIs (OpenAI, Groq, OpenRouter etc.)

  • Fully local models via Ollama or compatible setups

So you can go fully local, fully cloud, or hybrid — your choice.

If you want a deeper look, the full architecture and setup are available here:

The idea is simple: you own the backend, you own the data, you control the AI. 🚀
