Ex-Google X trio wants their AI to be your second brain — and they just raised $6M to make it happen


TwinMind, available on Android and iOS, passively captures background audio to gain context and deliver on-the-go summaries.

Co-founded in March 2024 by Daniel George (CEO) and his former Google X colleagues Sunny Tang and Mahi Karim (both CTOs), TwinMind runs in the background, capturing ambient speech (with user permission) to build a personal knowledge graph. In contrast, many competitors use React Native and rely on cloud-based processing, which Apple restricts from running in the background for extended periods, George said in an exclusive interview. To save time, he built a script that captured audio, transcribed it on his iPad, and fed it into ChatGPT — which began to understand his projects and even generate usable code.
