Krisp: The AI Layer That Makes Every Call Sound Like a Quiet Room
The dog barks the moment the client asks their question. The espresso machine, the roommate, the street below, every remote worker has lost a call to background noise, and muting yourself into conversation lag is not a fix. Krisp attacks the problem at the operating system level: an AI filter that sits between your microphone and every app, removing noise in both directions before it ever reaches the call.
The short version
Krisp installs as a virtual microphone and speaker on Windows and Mac, so it works with Zoom, Meet, Teams, Slack, Discord, softphones, anything that uses audio, with no per-app setup. It strips background noise from your side and, remarkably, from the other side too, cancels echo, and can also transcribe your calls and produce AI meeting notes and action items across every app you talk in. A free tier gives you daily noise-free minutes to prove it works with your setup.
Noise cancellation that actually holds up
Krisp's models separate human voice from everything else in real time, keyboard clatter, construction, cafe chatter, crying babies, and what passes through is only speech. Because it also filters incoming audio, the client calling from an airport gets cleaned up on your end, a direction most tools cannot touch. Echo cancellation handles the untreated home office, so your voice stops bouncing off the walls of the spare bedroom.
One setup, every app
The virtual microphone approach is the underrated part. Tools built into one meeting platform help only there, Krisp becomes your system microphone once and applies everywhere, including the phone dialers and niche apps that never get their own noise features. Select "Krisp Microphone" in any app's audio settings, or let it set itself as default, and forget about it. For call centers, sales teams, podcasters recording remote guests, and anyone in a loud environment, this is infrastructure, not an accessory.
The transcription layer
Since Krisp already sits in your audio path, it can transcribe any call without a bot joining, across every platform, and generate summaries and action items after. If you already live in a dedicated meeting notetaker you may not need it, but having accurate transcripts fall out of the same tool that cleans your audio makes it an easy consolidation for people who talk for a living.

Common questions
Does it work with my meeting app?
Almost certainly. Krisp appears as a microphone and speaker to your system, so anything that can pick an audio device can use it, including browser-based calls.
Will people know I am using it?
They will only notice the silence. Nothing joins the call or appears in the meeting, the processing happens on your machine before audio leaves it.
Is the free plan enough?
For a few calls a day, often yes. Heavy talkers hit the daily cap and upgrade, which is exactly how you find out it earns the subscription.
Bottom line
Krisp is one of those tools whose absence you hear immediately after trying it once. If calls are your job, the noise floor of your life stops being a professional liability. Install it free, take one call from your normal noisy reality, and listen to what the other side no longer hears.
