The appeal of TwinMind is clear: it promises to help users never forget anything important again, utilizing the smartphones we carry everywhere. This AI-powered "second brain" aims to assist our often forgetful primary brains in capturing vital information. CEO Daniel George describes it as akin to Jarvis from Iron Man—an AI that intuitively understands your life and provides timely assistance. I have been testing the TwinMind app in its beta phase for weeks. When activated during meetings or crucial discussions, it records and transcribes the conversation, later offering a concise summary and suggested follow-up actions. For example, after a client meeting, I noticed a pre-suggested question about competitor analysis across countries that led to a detailed summary on that topic. Unlike previous attempts at wearable AI assistants, like the Rabbit R1 or AI Pin, TwinMind operates as an app on your phone, eliminating the hassle of carrying extra devices and managing their maintenance.

George claims that the app efficiently runs on Apple Silicon without significant battery drain, lasting beyond 12 hours even with extensive use. TwinMind processes recordings locally via Apple’s hardware, ensuring that data isn't transmitted to the cloud by default, thus enhancing privacy. Users retain the option to encrypt data and can store backups on iCloud if desired. A year's worth of transcription data reportedly only uses 100 megabytes. For complex tasks, a premium version at $15/month integrates advanced AI models such as ChatGPT, Gemini, or Claude. The on-device processing keeps costs low—about 20 times cheaper than cloud-based operations—and allows functionality without internet access, which is another advantage. By keeping most data local, TwinMind helps enhance user privacy, as information remains on the phone unless a backup is chosen. With studies suggesting that 90% of our memories fade within a week, TwinMind offers a means to retain essential dates, tasks, and context for significant decisions. In the long run, personal AIs like TwinMind could evolve into comprehensive assistants, helping manage finances and household responsibilities while giving users control, rather than driving engagement for commercial purposes.
