Is Krisp Free? Yes, With a Clock On It
A renewing plan, not a sample you burn once. Where the hour goes, what the trial is, and the three habits that empty it early.
Yes — with a clock on it. The free plan gives you 60 minutes of noise cancellation a day, it resets at midnight GMT, it runs on one device, and it does not ask for a credit card. Verified August 2026. That is a real renewing plan, not a one-off sample you burn through once and never see again, and the distinction matters more than any feature comparison on this site. Separately there is a 7-day trial of the paid tier, also with no card, which is a different offer that readers mistake for the same thing every week. Where it goes wrong is the hour itself: 60 minutes disappears faster than anyone expects when one client call runs long.
Renewing plan versus one-time sample
This is the line I care about most as a referee, because it is where the word free gets abused across the whole category. Some tools hand you a fixed lump — say 30 minutes, once, forever — and label it a free tier. You use it, you like it, the tap is off. This allowance is not that. It comes back tomorrow, and the day after, indefinitely, with no payment method sitting on file waiting for a date. Judge the two differently even when the marketing copy reads identically.
- Renewing: 60 minutes a day, every day, resetting at midnight GMT on a single device.
- One-time: a fixed sample of minutes that never comes back, however long you wait.
- Trial: the paid tier in full for seven days, no card, and then it stops.
- Metered upload tools: a daily or monthly ceiling on files you send off to be processed.
Three of those four are honest offers. The one that catches people is the second, because a sample and a plan read the same in a pricing table and only one of them is still there next month. Cleanvoice, for instance, gives 30 minutes as a one-time sample rather than a renewing tier — useful for a single test, useless as a habit. Adobe Podcast Enhance is metered instead: a free hour a day in the browser, with each file capped at 30 minutes or 500 MB. Different shapes, different answers, and only the first one survives a routine.
What the free plan does not include
The clock is the limit, not the quality. You get the same processing on the free plan as on the paid one, which is unusual enough to say plainly — nobody has hidden the good model behind the paywall. What the free plan holds back is scale: one device, and 60 minutes across all of it. Run a two-hour workshop and you spend the whole allowance in the first half, with the noisy second half left uncovered. What the app itself looks like in daily use is written up separately.
Desktop-only is the real ceiling
Live noise cancellation runs on Windows 10 or 11 and macOS. The mobile apps do transcription and meeting notes, not live cleanup on a phone call. So if the honest description of your day is calls taken while walking, free or paid is not the axis you are arguing about — the product does not do that job at all, and I would rather lose the click than have you discover it afterwards. On a laptop it is a different fight entirely, and the free hour is a genuinely good place to start it. Which is where most readers are standing: a laptop, a shared room, a call at two.
The three ways people burn the hour
One: leaving it running when you do not need it. The allowance counts processing time, so a call where you spoke twice costs the same as one where you presented for an hour. Turn it off for the meetings where you are audience rather than speaker and the hour stretches noticeably further. My full read on how the processing behaves under load is in the Krisp review.
Two: forgetting which input is selected. It installs as a virtual microphone, so you pick Krisp Microphone as the input in the meeting app, in Discord, in OBS — one app at a time, and nothing switches over for you. People burn minutes with the app running while the meeting client is still listening to the hardware directly, which means paying the clock for nothing at all. There is a longer write-up of how Krisp noise suppression behaves in practice if you want the mechanics under that switch.
Three: spending it where something free already exists. macOS ships a Voice Isolation microphone mode, and on a Windows desktop with an RTX 2060 or better, NVIDIA Broadcast costs nothing at all — I score that matchup in Krisp versus NVIDIA Broadcast, and the comparison against what is already on your machine sits in Krisp versus built-in options. Save the 60 minutes for the calls where the room is genuinely against you. If none of it fits, the alternatives list is one page over.
Edge cases on the free plan
The reset does not land at your midnight
It resets at midnight GMT. Depending on where you sit, that is mid-afternoon or the middle of your working evening, so the allowance can refill halfway through a day or run out at a moment that feels arbitrary. Learn where the line falls in your own timezone once, and the plan stops behaving unpredictably.
One device means one at a time
A laptop and a desktop cannot both be covered on the free plan. Most people solve this by deciding which machine hosts the noisy calls and leaving the other one on whatever the operating system provides. If your week genuinely splits across two machines, that is a reason to look at the purse rather than fight the limit.
Free tools are not cracked tools
One more thing, because it comes up in my inbox. There are sites offering patched builds and unlocked installers of paid audio tools. Do not. You would be putting unsigned code between your microphone and your employer's calls to dodge a bill that a genuine free tier already covers for most people. The 60 minutes are right there, legitimately, and nothing about them expires.
Straight answers
Is Krisp free forever?
The free plan is not time-limited, so yes in that sense: 60 minutes of noise cancellation a day, renewing at midnight GMT, on one device, with no credit card. It is the daily ceiling that limits you, not an expiry date. The 7-day trial is the thing with an end date, and it covers the paid tier instead.
What is the catch with the free plan?
The clock and the device count. Sixty minutes a day covers a few short calls comfortably and does not cover a day of meetings. Only one device is included. Live cleanup is also desktop-only, so a phone call sits outside the offer entirely. Beyond that there is no catch: same processing, no card, nothing to cancel.
Is the free plan the same as the free trial?
No, and mixing them up is the most common mistake on this topic. The free plan is permanent, with a 60-minute daily allowance. The trial is seven days of the paid tier without a card, and then it stops. If you want to test life without the ceiling, take the trial. If you want a permanent baseline, stay on the plan.
Do I need a credit card to start?
No. Neither the free plan nor the 7-day trial asks for a card up front. That removes the usual reason people hesitate — there is nothing scheduled to charge you and nothing to remember to cancel. You decide to pay later, deliberately, or you keep using the daily allowance and never do.
Is there a free version for Android or iPhone?
Not for live calls. The mobile apps handle transcription and meeting notes; the live noise cancellation is Windows and macOS only. If your problem is what callers hear from your handset, the useful moves are a wired headset, stepping away from the noise, and holding the phone consistently rather than installing anything.
