Krisp

Krisp is an AI-powered noise cancellation application that removes background noise, echo, and unwanted sounds from voice communications in real time. It works at the operating system level, processing audio from any microphone or speaker, making it compatible with virtually all communication applications including Zoom, Microsoft Teams, Google Meet, Slack, Discord, Skype, and hundreds of others.

The technology behind Krisp uses deep neural network models that have been trained on a diverse dataset of noise types and speech samples. This training enables the AI to distinguish between human voices and background sounds with remarkable accuracy, removing keyboard clatter, traffic noise, construction sounds, crying babies, barking dogs, and even music while preserving the clarity and naturalness of the speaker's voice.

Krisp operates entirely on-device, processing audio locally without sending data to the cloud. This approach ensures privacy and security, as voice data never leaves the user's device. The local processing also means Krisp works reliably even in environments with poor or no internet connectivity, which is important for users in remote locations or those experiencing network issues.

One of Krisp's key advantages is its bidirectional noise cancellation. It can simultaneously remove noise from the microphone (so others don't hear background sounds) and from the speaker output (so the user doesn't hear noise from other participants). This dual functionality provides a cleaner conversation experience for everyone involved.

Krisp Meeting Assistant is an extension of the core noise cancellation technology, offering AI-powered meeting transcription, note-taking, and summary generation. This feature captures everything said in a meeting and provides actionable summaries, reducing the need for manual note-taking and helping teams reference what was discussed.

The application is particularly valuable for remote workers, customer support agents, online educators, podcasters, and anyone who participates in frequent voice or video calls. In environments like open offices, coffee shops, home offices with family noise, or outdoor locations, Krisp allows users to maintain professional communication standards regardless of their physical environment.

Krisp integrates as a virtual audio device, meaning setup is straightforward — users simply select "Krisp Microphone" and "Krisp Speaker" as their audio devices in any application. No additional configuration within individual applications is needed.
