Would you want a personal AI that acts as your twin mind? I’ve always dreamed of never forgetting anything. And instantly and effortlessly remembering anything I need, right away. Now, an AI-driven app called TwinMind might help me do something similar.
In this episode of TechFirst we chat with Daniel George, the CEO of TwinMind. This innovative AI app aims to become your second brain, capturing and processing your life events in real-time.
We chat about George’s inspiration behind TwinMind, its features, future vision, and the LLM tech making it possible. We also chat about privacy and security concerns.
Personal AI: episode summary
In this episode, John Koetsier talks with Daniel George, founder of TwinMind, a new AI app that acts like a “second brain.” Inspired by Jarvis from Iron Man, TwinMind continuously captures your life’s context—conversations, meetings, and digital activity—so it can recall anything and eventually act on your behalf.
Key takeaways:
- What is TwinMind?
TwinMind is a proactive personal AI assistant that listens to your conversations and monitors your context to build a memory model of your life. Over time, it learns your preferences, values, habits, and speaking style. - How it works:
The app runs on your device, using Apple Silicon to process audio locally and continuously with minimal battery use. You can run it all day, even in your pocket. A desktop companion captures what you see. Nothing is stored unless you opt in. - Main features:
- Instant recall of past conversations or events (“What did that person say about their dog six months ago?”)
- Context-aware suggestions and decision-making
- Learns your preferences for food, travel, media, and more
- Integrates with services like Google Calendar for meeting prep and summaries
- Future plans include vision input and full life modeling
- Philosophy:
TwinMind is built around user control and privacy. Unlike big tech AIs designed to maximize engagement, TwinMind exists to serve you. Everything can stay on-device, with optional cloud backup via iCloud. - Security & Privacy:
- Audio isn’t saved—only transcriptions and summaries are stored
- Local processing reduces cloud exposure
- Optional incognito mode stores data only on your device
- iCloud backup available, but not required
- No data retention from LLMs used in the cloud
- Tech stack:
TwinMind is LLM-agnostic and can route queries to any top model (OpenAI, Anthropic, Gemini, xAI, etc.). Most processing happens on-device using optimized small models (e.g. DeepSeek, LLaMA, Phi), making it fast, private, and affordable. - Why not build custom hardware?
George believes the smartphone is already the best wearable—well-optimized, ever-present, and powerful. Unlike failed AI gadgets (like Humane AI Pin or Rabbit), TwinMind is just a software upgrade. - Pricing:
- Free for most users, with unlimited memory and hours using on-device models
- $15/month for premium access to top-tier LLMs and best-in-class transcription
- Designed to be accessible and sustainable through edge computing cost savings
- Long-term vision:
Your personal AI could eventually manage your finances, schedule services, prioritize information, and even filter social media—so you can spend less time doomscrolling and more time living.
