What is Krisp?
Krisp is a Voice AI app that removes background noise from your calls in real time — on both sides — so you sound clear and don’t hear the other person’s noise either. It sits between your microphone/speaker and any conferencing app (Zoom, Teams, Google Meet, Slack and others) as a virtual device, so it works almost everywhere without changing your setup.
Beyond noise cancellation, Krisp has grown into a wider voice platform: it also offers an AI meeting note-taker (transcripts and summaries) and AI accent conversion. The noise cancellation runs on your device using machine learning, which is both fast and better for privacy.
What Krisp does
- AI noise cancellation — removes background noise (typing, traffic, pets, other voices) from your mic and from the people you’re talking to, in real time.
- Echo cancellation — reduces echo from rooms and speakers.
- AI note-taker / meeting assistant — records, transcribes and summarizes meetings across apps.
- AI accent conversion — aimed at call centers, softens or converts accents in real time for clearer understanding.
- Works everywhere — acts as a virtual microphone and speaker, so it plugs into virtually any calling or recording app.
How Krisp works and how to set it up
Krisp installs as a desktop app (Windows and macOS) and creates a “Krisp Microphone” and “Krisp Speaker” on your computer. You then pick those as your device inside your calling app, and Krisp cleans the audio as it passes through.
- Download and install Krisp from krisp.ai, then sign in.
- Toggle noise cancellation on for your microphone (and optionally your speaker).
- In Zoom/Teams/Meet, open audio settings and select Krisp Microphone as your mic and Krisp Speaker as your speaker.
- Join your call — background noise is filtered automatically.
Because the processing happens locally on your machine, there’s very little delay.
Is Krisp free? Pricing
Krisp has a free plan with a limited amount of noise-cancellation and note-taking each day/week, which is enough for light or occasional use. Heavier users move to a paid plan for unlimited noise cancellation and more meeting-assistant features, with monthly and annual billing.
Pricing and free-tier limits change, so check krisp.ai/pricing for the current numbers. A Claude Pro/Max-style chat subscription is unrelated — Krisp is billed separately.
Is Krisp safe?
Krisp’s noise cancellation processes audio locally on your device rather than sending your raw audio to the cloud, which is a strong privacy point. The company also publishes security and compliance information used by many enterprises and call centers.
The meeting-assistant/note-taker feature does process recordings to create transcripts and summaries, so for confidential meetings, review what’s stored and who can access it. Download only from the official krisp.ai site.
Pros, cons, and is it worth it?
Pros
- Excellent real-time noise removal that works in almost any calling app.
- Cleans both your side and the other person’s noise.
- Local processing = low latency and better privacy.
- Free plan is enough for light users.
Cons
- Heavy daily use needs a paid plan.
- Can use noticeable CPU on older machines.
- Aggressive settings can occasionally clip speech.
Is it worth it? If you take calls from noisy places (home, cafe, open office, call center), Krisp is one of the most reliable ways to sound professional, and the free plan lets you test it risk-free. If you’re always in a quiet room with a good headset, you may not need it.
Alternatives to consider: Zoom/Teams/Meet built-in noise suppression, NVIDIA Broadcast (needs an NVIDIA GPU), and Iris Clarity. Krisp’s edge is that it works across every app at once.
What to expect on your first call
After setup, the change is immediate: you switch your mic to “Krisp Microphone”, and typing, a TV in the background or a barking dog largely disappear for the people you’re talking to, while your voice stays clear. You can toggle it on/off mid-call to hear the difference. On very aggressive settings you may notice a slight softening of “s” sounds — dial it back if so.
Common setup mistakes to avoid
- Forgetting to select Krisp in the app. Installing isn’t enough — you must pick “Krisp Microphone” (and Speaker) inside Zoom/Teams/Meet.
- Doubling up noise suppression. If Zoom’s own suppression is also on high, turn it down so the two don’t fight.
- Running it on a very old laptop. Local processing uses CPU; close heavy apps if you hear glitches.
- Using the note-taker for confidential calls without checking storage settings first.
Who should get Krisp (and who can skip it)
- Get it if: you take calls from home, a cafe, an open office or a call center — anywhere noisy.
- Skip it if: you’re always in a quiet room with a good headset, or your platform’s built-in suppression already sounds clean to others.
