Interview Signal vs Krisp: clean audio or a structured interview?

Krisp and Interview Signal both run on your own computer with no bot in the call, but they fix different problems. As of October 2026, Krisp is a noise cancellation and accent conversion app for Windows and macOS with an AI note taker included in every plan, from $8 per user a month billed annually; it cleans up your audio and the other side's, then transcribes and summarizes. Interview Signal is a Windows and macOS desktop app built only for interviews, from $49 a month: it runs a question guide and a live scorecard during the call and writes a scorecard with the candidate's quotes and a client submittal afterward. Neither writes into an applicant tracking system. Choose Krisp if noisy calls and clear speech are your problem; choose Interview Signal if structured interview evidence is.

How do Interview Signal and Krisp compare at a glance?

"Not described" means we did not find it on Krisp's pages.

How does each one capture the call?

Krisp sits underneath your meeting app. Its noise cancellation page tells you to install Krisp and then select "Krisp Microphone for input and Krisp Speaker for output" in your conferencing app. Because it works at that level, Krisp's AI meeting assistant page says it "captures your conversations in any conferencing tool." Krisp's help center adds that you should select both the Krisp microphone and speaker "to make sure the full meeting is captured," and that recordings shorter than 30 seconds are not captured. If you would rather have a visible recorder, the Krisp Bot joins Zoom, Google Meet or Microsoft Teams as a separate participant once the host admits it.

Interview Signal also listens on the interviewer's computer and adds nothing to the meeting, labelling the microphone as the interviewer and the meeting's sound as the candidate. It works beside Zoom, Teams and Google Meet, needs Windows 10 or 11 or macOS 13 or newer, and has no bot, browser extension or mobile app.

On system requirements, Krisp's help center lists macOS 14 Sonoma or higher and 64-bit Windows 10 or Windows 11, and says Linux and ChromeOS are not supported.

Where is Krisp clearly better?

Audio. Krisp's noise cancellation removes background noise, competing voices and echo, and it works in both directions: "cancel my noise" for your side and "cancel others' noise" for what you hear. Its help center says the noise cancellation itself is "done locally on the device" and the audio is not sent to Krisp's servers for it. For a recruiter screening candidates who call from cars, kitchens or busy streets, that is a real advantage, and Interview Signal has nothing equivalent.

Krisp also offers accent conversion on the speaker side and the listener side, with daily limits that depend on the plan (1 hour a day on Core, per the pricing page), a mobile app for in-person meetings, and audio or screen recording. If you want a recording to replay, Krisp has one and Interview Signal does not.

Where is Interview Signal clearly better?

The interview itself. Krisp's notes are general meeting output: summaries, decisions and action items. We did not find a question guide, interview scorecard or candidate submittal described on Krisp's pages.

Interview Signal builds a question guide from the job description, pins must-ask questions until they are asked, suggests follow-ups with a reason (probe, clarify or evidence), fills a scorecard as the interview goes, and scores on demand with Evaluate, with an optional second model (Dual AI). A private answer check flags answers that read as AI-written or read aloud and suggests a question to try; it never changes a score or reaches the submittal. After the call, each score carries the candidate's own quotes, checked against the transcript, and a client submittal is drafted in your agency's template. For panels, questions are split across interviewers and only which questions were asked and the scores are shared, never transcripts.

Which one handles phone screens?

Krisp's pricing page lists the Core plan's mobile app as an "outbound phone call recorder," and Krisp's mobile help article says the mobile app does not support noise cancellation yet. On a computer, Krisp works through the same virtual microphone and speaker you select in a meeting app, so test your own softphone on a mock call before a real screen. Interview Signal captures any phone screen that runs through the computer's audio, such as a softphone, and has no mobile app. See how to record a phone screen for the options.

Where does the interview data go?

Krisp's help article on what data it sends to the cloud says meetings are transcribed in the cloud and the data used for transcription is deleted after processing, while recordings, with or without the bot, "are kept in the cloud," encrypted. Its recording FAQ lists 10 GB or 60 GB of storage depending on plan, recordings of up to 4 hours, and the option to delete a recording but keep the transcript. The pricing page lists SOC 2 Type II and GDPR, says meeting data is never used to train Krisp's models, and offers on-device private transcription and recordings on Enterprise.

Interview Signal keeps transcripts, quotes, candidate names, notes and submittals on the recruiter's computer. Audio goes to a speech-to-text provider in short chunks during the call and is not retained, and our server keeps only counts and durations (security details).

How much does each one cost?

From Krisp's pricing page and ours, as of October 2026. Totals are our arithmetic.

Krisp's pricing FAQ says there is no separate noise-cancellation-only plan, because noise cancellation is in every plan. On price alone, Krisp wins comfortably for anyone who uses it every week.

How do they handle candidate notice?

Krisp's help article on recording meetings says you can enable "Notify others you're using Krisp" under Settings, Privacy & Consent, and warns that "some platforms may block chat messages or audio prompts," so participants should be informed another way too. Interview Signal includes a read-aloud consent line, notice text by jurisdiction and a one-click pause. With either tool, tell the candidate out loud; our consent script has wording. This is general information, not legal advice.

Should you choose Krisp or Interview Signal?

Choose Krisp if:

• Background noise or hard-to-follow audio is what spoils your calls.
• You want one low-cost app for every meeting, with notes as a bonus.
• You want recordings to replay, or a bot option for meetings you cannot attend.
• You want CRM integrations such as HubSpot or Salesforce.

Choose Interview Signal if:

• You want a question guide, follow-ups and a live scorecard during the interview.
• You need a scorecard backed by the candidate's own words, or a client submittal.
• You want transcripts kept on your own computer.
• You can accept no ATS integration, desktop only, no video, and a newer product with few public reviews.

Best for, in one line: Krisp is best for anyone whose calls suffer from noise; Interview Signal is best for recruiters whose write-ups need structure and evidence.

What should you test before deciding?

1. Record a mock screen from a genuinely noisy room and compare
   the transcripts each tool produces.
2. Run one phone screen on your real phone setup.
3. Compare Krisp's summary with Interview Signal's scorecard
   for the same call.
4. Check where each one keeps the recording or transcript.
5. If you try both on one computer, test the audio routing on a
   mock call before a real candidate.
