Altalt Overview

Altalt is an innovative, free AI-powered lecture notetaker designed exclusively for macOS, enabling users to focus entirely on their lectures while the application handles real-time transcription and organization of notes. Developed with a strong emphasis on privacy and performance, Altalt operates entirely on your local machine, meaning no data ever leaves your device, ensuring strict security and confidentiality for all your information.

How to use Altalt

Using Altalt is straightforward. First, download and install the application on your macOS device (version 13.3+ with Apple Silicon is required). You can either download it directly or use Homebrew with brew install --cask altalt-org/alt/alt. Once installed, simply launch Altalt before your lecture, and it will automatically begin transcribing and organizing your notes in real-time. This allows you to concentrate on listening and understanding, rather than manual note-taking.
