What is Krisp?
Krisp is an AI-powered noise cancellation app that removes background noise, echoes, and unwanted sounds from any audio communication in real time.

The technology runs locally on your device, meaning audio data never leaves your computer, addressing enterprise privacy concerns. The free tier provides 60 minutes of noise cancellation per day.
