Nebula DeckAlways-on sandboxed AI workspace for chat apps

SecondBrain

SecondBrain acts as a crucial memory layer for your phone's AI interactions. Speak naturally, and it automatically organizes your thoughts into notes, calendar events, and reminders. Crucially, it then shares this contextual memory across popular AI platforms like Claude, ChatGPT, and Gemini, ensuring your assistants never start from scratch again. This innovative approach tackles the common frustration of re-explaining background information to different AI tools.
