I think you mean kool-aid, which refers to the well known American fruit-flavored drink mix brand. "Cool aid" on the other hand is completely nonsensical.
Thanks for pointing out the issue with the video, should be fixed now. Interesting product you sent, although personally I'm not a huge fan of these uncanny valley-esque AI avatar tutors. Might just be me though.
Hume has an API for realtime expression detection - confusion states get injected into the LLM, kind of useful for better turn detection if the user is struggling but honestly doesn't work that well right now

Show HN: Lingle – Voice agent to simulate zoom-based personal language lessons

https://lingle.ai/

In my opinion the best way to learn a language (outside of moving to a different country) is to get a personal tutor and have consistent 1 on 1 lessons. I used Preply or iTalki for this back in the day but had issues with flexibility and pricing.I've been trying to simulate the experiences that I had on those platforms with a voice agent.You can try a demo for free here (or watch a video of me...

Sounds like it might be a challenge but I can definitely see the use case!

Hey HN! I’m Andrew, and I’ve been building Cortex (https://cortexdesktop.com/) for the last few weeks. Cortex is my attempt to reimagine how we interact with computers - starting with a simple interface, but aiming for something deeper: an AI layer over your OS that understands what you’re doing, remembers it, and helps you dynamically.Right now, Cortex is just a floating overlay you can...
