What is Krisp

Krisp is an AI-powered voice productivity application best known for its real-time noise cancellation. Founded in 2017, Krisp solves a problem that became universal with the rise of remote and hybrid work: background noise on calls. Whether it is a barking dog, street traffic, keyboard clatter, a noisy café, or family in the next room, Krisp uses AI to remove unwanted sound from both the user's outgoing audio and the incoming audio of other participants — in real time, as the call happens.

What makes Krisp distinctive is where it operates. Rather than living inside one conferencing platform, Krisp works at the system level as a virtual microphone and speaker. This means it functions with virtually any application that uses audio — Zoom, Microsoft Teams, Google Meet, Slack, Discord, dialers, and more — without any per-app configuration. The user selects Krisp as their audio device once, and noise cancellation applies everywhere.

Over time Krisp has expanded beyond noise removal into a broader voice-productivity tool. It now includes features such as echo cancellation, voice cancellation (removing other people's voices in a shared space), an AI meeting assistant that transcribes calls and generates notes and summaries, and call analytics. Adopted by individual remote workers, customer support and sales teams, and call centers, Krisp has become a widely used layer for making any voice conversation clearer and more professional.

Key features

• Real-Time Noise Cancellation — Removes background noise from both outgoing and incoming call audio as the conversation happens
• Echo Cancellation — Eliminates echo and reverberation caused by rooms, speakers, and hardware setups
• Voice Cancellation — Filters out other people's voices in shared or open spaces so only the intended speaker is heard
• App-Agnostic Operation — Works as a virtual microphone and speaker across virtually any conferencing or communication app
• AI Meeting Assistant — Transcribes calls and generates notes, summaries, and action items
• Call Analytics — Provides insights such as talk time and meeting statistics for individuals and teams

Pros

✅ Noise cancellation is highly effective and genuinely improves call clarity and professionalism

✅ Works across nearly every communication app with a single one-time setup, requiring no per-app configuration

✅ Cleans both directions of a call — users hear others more clearly and are heard more clearly themselves

✅ Lightweight and runs in the background, integrating into existing workflows without disruption

✅ The expansion into transcription and AI notes adds meeting-assistant value beyond pure audio cleanup

Cons

⛔️ Real-time AI processing uses CPU and can affect performance or battery life on lower-powered devices

⛔️ The free plan caps noise-cancellation minutes and assistant features, pushing regular users to a paid tier

⛔️ In rare cases aggressive filtering can slightly clip or alter the user's voice or remove intended sounds

⛔️ Its meeting-assistant and transcription features are newer and less deep than dedicated meeting-intelligence tools

Who is using Krisp

Krisp is used by anyone whose work depends on clear voice calls. Remote and hybrid workers use it daily to sound professional regardless of their environment, whether working from home, a café, or a co-working space. Customer support agents and call-center teams use it at scale to remove ambient noise and improve the quality of every customer interaction, which can directly affect satisfaction scores. Sales teams use it so that discovery and demo calls are not undermined by distracting background sound. Podcasters and content creators use it to clean up recordings. Freelancers and consultants use it to present a polished impression on client calls. Its value is broadest for distributed teams and customer-facing roles, where consistent audio quality across unpredictable environments matters most.

What makes Krisp Unique?

Krisp's defining advantage is that it solves a single, universal problem extremely well and does so independently of any platform. Most noise-reduction features are built into a specific conferencing app and only work there. Krisp sits one layer below, operating as the system's audio device, which means a user configures it once and gets clean audio in every app they ever use for a call. That platform-agnostic design is simple but genuinely valuable — it removes the inconsistency of relying on whatever noise handling each individual app happens to offer.

The bidirectional cleanup is a second distinguishing strength: Krisp improves not only how the user sounds to others but how others sound to the user, which matters when a teammate or customer is the one in a noisy environment. Combined with its expansion into transcription and AI meeting notes, Krisp has grown from a focused utility into a broader voice-productivity layer — but its core noise-cancellation quality remains the reason most people install it.

Final thoughts

Krisp does one thing exceptionally well: it makes voice calls clearer by removing the noise, echo, and stray voices that undermine professional communication. Because it works at the system level across every app, it delivers that benefit with almost no friction — a single setup that quietly improves every call from then on. For remote workers and customer-facing teams, it is one of the highest-value-per-effort tools available.

Its limitations are modest: some CPU overhead on weaker devices, free-tier caps, and rare over-filtering. The newer transcription and meeting-assistant features are a useful bonus but not yet a reason to choose Krisp over a dedicated meeting-intelligence tool. Judged on its core purpose, though, Krisp is a polished, reliable, and genuinely useful application — and for anyone who takes calls from unpredictable environments, it earns an easy recommendation.
