Tanna AI is an automatic AI note-taking tool designed to help streamline the process of learning and studying. Users provide the tool with audio or video content such as lectures or meetings, and the AI technology transcribes and summarizes this content into notes. Functionality includes easy sharing of audio/video content from Chrome or directly recording a lecture/meeting, automatic AI transcription, note-storage, and the capacity to test and further explore concepts post-transcription. Tanna claims to offer an innovative approach to studying and note-taking by automating the process, which frees users to focus more on the actual content rather than the note-taking task. Services are extended in various plans, including a free trial version with certain usage limits. Tanna AI works primarily with laptops or desktops using a Chrome-based browser and has limited functionality on mobile via the web browser. Transcripts and videos provided by users are securely stored on encrypted servers in compliance with standard data storage policies.
