Krisp — The AI Noise Cancellation App That Makes You Sound Like You’re in a Quiet Office

Your kid is yelling in the next room. Your neighbor is drilling something. You’re about to join a client call from a coffee shop. You don’t have to explain any of that — you just don’t want anyone to hear it.

Krisp is an AI noise cancellation app that removes background noise from your calls in real time, on both ends — yours and theirs. It’s built for anyone who takes calls from a home, café, or shared space and wants to sound like they’re in a quiet studio.

What it is

Krisp is a small app that sits between your microphone (and speakers) and whatever calling app you use — Zoom, Google Meet, Slack, phone calls, anything.

It uses AI to filter out non-voice sounds — typing, dogs barking, traffic, other conversations — so only your voice comes through. It also works in reverse, cleaning up noise on the other person’s end so you don’t hear their chaos either.

Try it in 5 minutes

1. Go to Krisp’s website and download the app for your computer (Mac or Windows) or phone.
2. Install it and let it set up as your default microphone and speaker — it needs this to filter sound before it reaches your calling app.
3. Open the Krisp app and turn on “Noise Cancellation” for both mic and speaker.
4. Join any call — a test meeting, a call with a friend, or Krisp’s own built-in test feature.
5. While on the call, try this simple check with whoever you’re talking to:

Ask the other person: "Can you still hear the noise around me?
Turn Krisp off and on during our call and tell me what changes."

Toggle the Krisp icon on/off mid-call and see if they notice the difference.

A real example

Say you’re on a video call with a coworker while your washing machine is running loudly in the next room, plus your cat is knocking something off a shelf.

With Krisp off, your coworker says: “I can hear a machine and something falling — is everything okay over there?”
With Krisp on, same moment, they say: “Sounds totally quiet on your end, all good.”

That’s the whole pitch — it’s not magic, it’s just very good at telling “voice” apart from “everything else” and muting the everything else.

Honest take

Best for:
– Remote workers taking calls from home, shared offices, or noisy environments
– Anyone doing frequent video meetings who wants consistently clear calls without buying new gear
– Freelancers or support agents on calls all day who want to sound professional regardless of location

Not for:
– Crowded spaces with other people actually talking near you — Krisp is tuned to strip out non-voice noise, but a real human voice close to your mic (another conversation at the next table) can still leak through since it sounds like “voice” too
– Heavy daily users who go past the free tier — Krisp’s free plan gives limited minutes per week, after that you’ll want the paid plan

The free tier gives you a real amount of usage to test it properly before deciding if it’s worth paying for.

FAQ

Is it free? Yes, there’s a free tier with limited weekly minutes of noise cancellation. Paid plans remove the limit and add extra features like meeting notes.

Is it safe? Yes — Krisp processes audio on your device in most cases and doesn’t record or store your calls. It’s a noise filter, not a call-recording tool.

Do I need an account? Yes, a free account to download and activate the app, but no credit card needed to start.
