Free, unlimited local AI notetaker for lectures & meetings
Most AI notetakers limit you to ~300min/month. As a student with 60+ hours of lectures, that wasn't enough. So I built Alt. It runs local AI models on your Mac for unlimited, free, private transcription. Optimized for the Apple Neural Engine, it uses minimal battery and needs no internet. Now supporting 100+ languages and optional Pro access to SOTA models like GPT-5.1 & Gemini 3 for advanced summaries.
Hey Product Hunt! š Iām Coby, a CS university student in South Korea. I built Alt because I was broke and frustrated. I used to use popular AI notetaker services to transcribe my lectures, but Iād burn through their monthly "Pro" credits in just 3-4 classes. They usually cap you at 300 minutes, but as a student, I had 60+ hours of lectures a month. That led me down a rabbit hole of trying to run Whisper models locally on my Mac. Naturally, I thought building an app around it would be easy. (Spoi
Wow impressive accuracy in German! What model size are you using?
It's nice that it works offline but does it handle stuff that needs an internet connection too? Like web searches, for example?
As someone with tons of lectures, this is exactly what I needed!!
I was getting tired of doing everything fully online, but being able to record anytime, anywhere is actually sick. I use it all the time lol.
