Krisp
AI background noise cancellation for calls, meetings, and recording
Krisp uses a deep learning AI model to remove background noise, echo, and background voices from your microphone and speaker in real time. It works with Zoom, Microsoft Teams, Google Meet, Discord, and any other application that uses audio — no special microphone or GPU required. Krisp runs entirely on your local machine, keeping your audio private while delivering studio-grade noise removal for remote workers, podcasters, and customer support teams.

Krisp is an AI-powered audio enhancement application founded in 2019 by Artem Uzhviy. It uses a deep learning model — trained on millions of hours of audio containing hundreds of types of background noise — to isolate and remove unwanted sounds from your microphone stream in real time. Unlike hardware noise-canceling headphones that only reduce noise for the wearer, Krisp removes noise from the audio you transmit to others on calls, ensuring the people you talk to hear crisp, clean speech regardless of your environment.
Krisp works by installing a virtual audio device on your Windows or macOS computer. When you select "Krisp Microphone" as your audio input in Zoom, Teams, Google Meet, Discord, or any other communication app, your real microphone audio passes through Krisp's AI noise filter before reaching the application. The model runs entirely locally on your CPU — no audio is sent to Krisp's servers — which means low latency and strong privacy. Krisp also offers speaker-side noise cancellation, removing background noise from the audio you receive from others.
Beyond basic noise cancellation, Krisp has expanded into an AI meeting assistant. Pro and Business subscribers can access real-time meeting transcription, automated meeting notes, and action item extraction — turning Krisp from a pure audio tool into a productivity platform for remote teams. These features work across any conferencing platform without needing a separate bot or calendar integration.
Krisp is particularly valued in environments where background noise is unavoidable: open-plan offices, home offices with family members nearby, coffee shops, and call centers. For customer-facing professionals, eliminating background noise can meaningfully improve customer perception and call quality scores. The Business plan adds team-wide deployment, usage analytics, and centralized control, making Krisp a popular choice for enterprises managing distributed workforces.

Frequently Asked Questions
What is Krisp?
Krisp is an AI-powered noise cancellation application for Windows and macOS. It installs as a virtual audio device and uses a locally-running deep learning model to remove background noise, echo, and background voices from your microphone stream in real time. It works with Zoom, Teams, Google Meet, Discord, and any other app that accepts a microphone input — without requiring a noise-canceling headset or GPU hardware.
Is Krisp free?
Krisp offers a free plan that provides 60 minutes of noise cancellation per week. For remote workers or anyone using Krisp daily, the free tier is insufficient. The Pro plan at $8/month provides unlimited noise cancellation, background voice removal, echo cancellation, and the AI Meeting Assistant with real-time transcription. Business plans at $15/user/month add team management features and analytics for organizations.
How does Krisp work?
Krisp installs as a virtual audio device on your computer. You select "Krisp Microphone" as the input device in Zoom, Teams, or any other communication app. Your physical microphone audio passes through Krisp's AI noise model — which runs entirely on your local CPU — and only the cleaned audio reaches the app. The AI was trained on millions of noise samples and can identify and remove hundreds of different background noise types while preserving your voice quality.
What platforms and apps does Krisp support?
Krisp works with any application on Windows or macOS that uses a microphone or speaker. Verified integrations include Zoom, Microsoft Teams, Google Meet, Webex, Slack Calls, Discord, Skype, GoToMeeting, RingCentral, and recording software like Audacity. Because Krisp operates as a virtual audio device at the OS level, it works with any app that allows you to select your microphone — no platform-specific plugin required.
How is Krisp different from NVIDIA RTX Voice?
Both tools use AI for real-time noise cancellation, but they differ significantly in requirements. NVIDIA RTX Voice requires an NVIDIA graphics card (and performs best with RTX series GPUs) and is Windows-only. Krisp runs on any modern CPU, supports both Windows and macOS, and does not require any specific hardware beyond a standard microphone. For users without NVIDIA GPU hardware, or on macOS, Krisp is the practical choice for AI-powered noise cancellation.
Can businesses use Krisp for teams?
Yes, Krisp is well-suited for business deployment. The Business plan at $15/user/month provides centralized team management through an admin dashboard, per-user usage analytics, SSO integration for enterprise identity providers, and volume pricing. Enterprise plans offer custom contracts, dedicated customer success support, compliance documentation, and SLA guarantees. Krisp is widely adopted by remote-first companies, call centers, and customer support operations where audio quality directly affects customer experience.
