Krisp vs IRIS Clarity: Two Live Noise Removers, Round by Round

IRIS Clarity vs Krisp comes down to what you want besides quiet. If live, two-way noise removal at the lowest monthly bill is the whole job, IRIS Clarity takes this bout: £6.50 a seat billed monthly, against Krisp's $16 a user month to month. If you want transcripts, AI notes and call recording in the same subscription as the noise removal, Krisp takes it, at $8 a user a month on an annual plan. Both prices come from the vendors' own pricing pages, checked on 9 Oct 2026.

Skip this card if you need a native Linux app, because neither corner ships one, or if you came looking for the old AppSumo lifetime deal, which is no longer on sale. One more thing before the bell: IRIS still wins more rounds below.

Corner cards

Red corner: Krisp

Krisp is desktop software for macOS 14+ and for 64-bit editions of Windows 10 and 11. It slots in between your headset and every call app by way of two virtual devices: Krisp Microphone cleans what you send, Krisp Speaker cleans what you hear, and all of that work happens locally on your computer. Since its turn toward meeting AI, the same subscription also carries a note-taker that records without sending a bot into the meeting. A permanent $0 tier no longer exists: the trial lasts 7 days and asks for no card, and after it you either pay or lose access.

Blue corner: IRIS Clarity

IRIS Clarity comes from IRIS Audio Technologies and is delivered three ways: a desktop app for Windows and Mac, a Chrome extension, or an SDK for companies building noise removal into their own software. The pitch is narrow and specific. It removes noise from both ends of a call in real time, and the app only has to run on one side of the call. It is sold per seat, with an Enterprise tier aimed at contact centres, and it has a listing on the Talkdesk AppConnect marketplace.

Tale of the tape

The same tape in words, for anyone on a screen reader or a slow connection. Krisp Core lists at $8 per seat a month on a yearly commitment, against $16 without one; Advanced lists at $15 and $30 on those two terms, and Enterprise is custom. IRIS lists its Professional plan at £6.50 a seat on monthly billing, and Enterprise is by quote with a minimum of 100 seats. Krisp's trial is 7 days. IRIS's pricing page says 14.

Delivery is where the tape splits hardest. Krisp is desktop-only for live noise cancellation, with one exception: its iOS app now cleans outgoing calls to US numbers placed through the Krisp app. IRIS covers Windows and Mac desktops, Chrome, and other people's software through the SDK. Both clean incoming audio as well as outgoing. Only Krisp bundles meeting notes, transcription, recording and accent conversion.

Round 1: noise and background voices

Both corners do the same headline job: strip background noise from a live call before anyone hears it. Where they differ is in how much they document. Krisp lists three separate treatments inside its Core and Advanced plans: noise cancellation, a Voice Isolation feature that removes nearby background voices, and echo cancellation, which is on by default. IRIS says Clarity "removes background noise and enhances voice quality in real time" and shows a voice isolation heading above its audio samples, without saying what that does to a colleague talking behind you.

I have not run a listening test for this card, and I won't pretend otherwise. On documented scope alone, the round goes to Krisp, because background chatter is the noise that defeats simple filters and Krisp names it as a target. If IRIS publishes the same level of detail, this round gets rescored.

Round 2: both ends of the call

Two-way cleaning is where this pairing is closest. Krisp cleans incoming audio through Krisp Speaker, so a caller sitting in a café arrives quieter in your headphones. IRIS frames the same idea for a different room: its call page says Clarity removes noise "from both ends of the call" and that only one side needs to install anything, which is aimed squarely at support agents whose customers never will.

On paper these are one capability described for two audiences. Even round.

Round 3: price

Here the blue corner lands clean. The Professional plan from IRIS costs £6.50 per seat, and the plan card is labelled "billed monthly". The page carries an annual toggle, but only that one price rendered when I read it on 9 Oct 2026. Krisp Core is $16 a user month to month, or $8 if you commit to a year. Comparing pounds with dollars is untidy, but this arithmetic isn't close: for £6.50 to cost as much as Krisp's $16 month-to-month rate, a pound would have to be worth about $2.46.

Against Krisp's annual rate, the gap shrinks to a currency question you should settle with your own bank's rate on the day you buy. Even then, IRIS reaches its price without a year-long commitment. Round to IRIS.

The lifetime deal question

The thing people search most about this pairing is the lifetime deal, so it gets a straight answer instead of a score. IRIS Clarity did sell on AppSumo as a one-off purchase, with tiers set by user count: 2 users on the first tier, 4 on the second and 8 on the third, each user allowed 5 devices. When I read that listing on 9 Oct 2026, it said the deal was unavailable.

If you bought it back then, your licence is whatever that deal said, and nothing on this card changes it. If you didn't, there is no lifetime option to set against Krisp today, and Krisp's pricing page lists only Core, Advanced and Enterprise subscriptions. A "lifetime key" for either product sold anywhere other than the vendor's own pages is a risk I'd walk away from.

Round 4: platforms

IRIS takes this one on reach. A Chrome extension matters if your calls live in a browser tab, and the SDK matters if you run a contact centre that wants noise removal inside its own softphone. The Talkdesk listing, at version 1.0.1 and updated on April 14, 2026, shows that route is real rather than a slide in a sales deck. Krisp's desktop app covers macOS and Windows and nothing else: no Linux build, no ChromeOS.

Krisp's counterpunch is the phone. Its iOS app cleans outgoing calls to US numbers placed through the app, which is narrow but more than IRIS documents for mobile. It isn't enough to take the round. IRIS on reach.

Round 5: extras

This is where the fight changes weight class. Krisp Core includes an unlimited AI note-taker that records without a bot joining the call, plus transcripts, audio and video capture, AI-written notes and action items, an hour a day of accent conversion, integrations with tools such as HubSpot, Slack and Notion, and 10 GB of storage. IRIS sells noise removal and makes no claim to be a meeting assistant.

If you already pay for a note-taker, Krisp's extras are a second copy of something you own, and that's a fair reason to buy the cheaper specialist. If you don't, the extras are why Krisp costs what it does. Round to Krisp, with that asterisk.

Round 6: trial length

Krisp's trial unlocks the premium features for 7 days with no card required, though accent conversion is limited during it. When the week ends without a purchase, its Terms of Use say access stops, and you keep 90 days to export anything you recorded. IRIS's pricing page offers 14 days, although one line on its call page still says 7 and its Talkdesk listing says 30. Treat the pricing page as the current offer and confirm the length at sign-up. Twice as long, so round to IRIS.

The decision

On my card IRIS takes three rounds, Krisp takes two, and one is even. That makes it a split decision, and the split runs along a clean line: IRIS for people buying quiet, Krisp for people buying quiet plus a written record of the call.

Pick IRIS Clarity if you want noise removal and nothing else, prefer paying month to month, take your calls in a browser tab, or are equipping a contact centre. Pick Krisp if you want the call cleaned and written up by one subscription, worry most about voices in the background, or need noise-free outgoing phone calls on a US iPhone.

Flip the card: when the other corner wins

Run a support queue on Talkdesk? Ignore my extras round completely. Nobody answering tickets needs AI meeting summaries, and IRIS's marketplace listing is the shorter path from purchase to working headset. Book back-to-back client calls as a consultant? Flip the price round instead: one annual Krisp seat that also writes your call notes may replace two subscriptions, so price your current note-taker before you decide.

Edge cases

Teams past a hundred seats

IRIS Enterprise starts at 100 seats and is priced by quote. Krisp Enterprise is also custom, adding single sign-on, SCIM provisioning and HIPAA support. Neither publishes a number, so at that size this card can't help you. Get both quotes in writing.

Gaming on Discord

If your noise problem lives in Discord voice channels, check the free option first. Discord's own noise suppression runs a Krisp model inside Discord at no cost, though Mac users need an Apple-silicon machine running macOS 12 or newer. My card against the built-in toggles covers that bout.

Mixed-currency teams

IRIS showed a price in pounds only when I read it. If your finance team buys in dollars, ask IRIS for a dollar quote rather than converting a list price yourself.

Ringside questions

Is IRIS Clarity better than Krisp?

For pure noise removal at the lowest month-to-month price, yes, on my card. For noise removal plus meeting notes, recording and transcripts, Krisp is the stronger buy. Neither answer comes from a listening test; both come from what each vendor documents, read on 9 and 10 Oct 2026.

Can you still buy the IRIS Clarity lifetime deal?

No. The AppSumo listing said the deal was unavailable when I read it on 9 Oct 2026. Earlier buyers keep whatever terms their deal set. New buyers pay the per-seat subscription, which was £6.50 a seat billed monthly on IRIS's pricing page that day.

How much does IRIS Clarity cost?

The Professional plan lists at £6.50 a seat on monthly billing, and the pricing page offers a 14-day trial. Enterprise is priced by quote and needs at least 100 seats. No dollar price appeared on the page when I read it.

Can I try both before paying?

Yes. Krisp's trial runs 7 days with the premium features unlocked and asks for no card; after that, access stops until you buy Core or Advanced. IRIS offers a 14-day trial on its pricing page. Run them in different weeks so each gets a fair test on real calls.

Do both clean the other person's audio?

Yes. Krisp cleans incoming sound through its Krisp Speaker device. IRIS says Clarity removes noise at both ends of a call with only one side running the app. If your problem is a noisy caller rather than your own room, either corner answers it.
