Krisp

Krisp is a real-time AI noise-cancellation tool that sits between your microphone and your meeting software, so apps like Zoom, Riverside, SquadCast, Google Meet, and Teams pick up a cleaner signal than what's actually in the room. It also removes background voices, echo, and even other people on your guest's end — which is the killer feature for podcasters interviewing someone in a noisy office or open-plan home.

The free tier gives you 60 minutes of noise cancellation per day plus transcription. Pro at $8/mo unlocks unlimited use and AI summaries, and Business at $15/mo adds team management and integrations. Runs on macOS, Windows, iOS, and Android.

The big selling point is that processing happens on-device, not in Krisp's cloud, which makes the privacy story strong for sensitive conversations. The trade-off most podcasters miss is that Krisp's model treats voice transients aggressively, and on quieter speakers or whispery delivery you can hear the algorithm pump or eat the tails of words.

The right way to use it is as a fallback when a guest has a bad room, not as your primary processing chain. If your show records into a proper double-ender, you don't need Krisp at all. If you live on Zoom interviews with civilians, it's a no-brainer.
