TwinMind is a memory capture and transcription app positioned as an "AI second brain." It can record the user's conversations, thoughts, meetings, classes, and other content around the clock, and automatically transcribes, translates, organizes, and summarizes them to form a searchable personal memory library.
Main capabilities
- Around-the-clock capture: Supports continuous capture for more than 16 hours without consuming too much battery.
- Automatic language detection and real-time translation: Can recognize the language the user speaks and hears, and translate in real time.
- Transcription and summaries: By default, only the transcript is saved, and the audio is deleted by default after transcription; supports summaries, daily summaries, and reviews.
- Offline/on-device mode: When enabled, data is stored only on the device and is not uploaded to the cloud; cloud backup is optional.
- Memory organization: In the evening, automatically categorizes and archives the day's content by people, places, projects, etc., forming a private wiki.
- AI context enhancement: Connects personal memories to compatible AI tools such as ChatGPT, Claude, and Gemini, allowing these AIs to answer questions based on the user's life context (conversations, emails, web pages, etc.).
- Content creation: Generates presentations from sales calls, documents from brainstorming, images from spoken ideas, and can connect to commonly used apps.
- Action items and email drafts: See ready-written to-dos and email drafts upon waking up.
