Alt

Alt is a completely free, no-time-limit AI lecture notetaker for macOS that runs fully on your device. Unlike cloud/API-based apps like Otter.ai or Granola — which are expensive and limit recording time — Alt has no usage limits and never sends audio to external servers. Alt is also far lighter and more accurate than typical local STT tools thanks to our optimized on-device AI engine. • Real-time transcription for lectures, classes, and online meetings • Works with Zoom, Google Meet, and any platform via system audio • Real-time translation in 100+ languages • Structured notes with key points and auto summaries • New: AI Chat for asking questions about your lecture content • New: Lecture slide/document summarization • Fully local AI — no cloud, no API costs, and complete privacy • Designed for Apple Silicon with extremely low memory and battery usage Alt is built for students and professionals who want reliable, unlimited lecture notes without paying for cloud-based tools. Since Alt has no server or API costs, it can remain 100% free while protecting all your data on your own Mac.
