In one paragraph
Krisp puts a virtual microphone between your real one and whatever app you call from, and cleans both directions on-device — your noise going out, other people's coming in. It works with anything that has an audio-device picker, on Windows and macOS alike, which is coverage most of this index can't match. The free 60 minutes a day is a real plan, not a trial countdown. Rivals beat it on price or on a single platform; none of them match its coverage. Best at: being the one tool a mixed team can standardise on.
Strengths
- Cleans inbound audio too — a rarity this index can count on one hand
- App-agnostic: works with anything that exposes an audio-device picker
- The free tier is perpetual — 60 min/day forever, not a 14-day teaser
Limitations
- Unlimited cancellation requires Core at $8/mo billed annually
- Month-to-month billing doubles the effective price to $16
- Meeting notes and transcription crowd the app if all you want is quiet

Mini-FAQ
Is Krisp free?
Partly. The free plan gives 60 minutes of cancellation per day (more with a work email), forever, one device at a time. Unlimited use starts at $8/mo billed annually. Verified Jul 28, 2026.
Is Krisp safe to use?
Cancellation runs on-device — call audio isn't routed through Krisp's cloud to be filtered. Optional extras like transcription and AI notes do use cloud processing; leave them off if that matters to you.
