Remove Sensitive Speech From a Recording — Privately

Bleep or mute names, numbers, and any other sensitive detail from an audio file, right in your browser. Transcribe, review, redact, and export — nothing is ever uploaded.

How it works

1

Drop in a recording

Audio or a video file with audio — we'll give you back the redacted audio track. Nothing is uploaded; the file never leaves your device.

2

It's transcribed and flagged as it goes

Speech recognition that runs on your device turns the recording into a transcript live. Phone numbers, card numbers, emails, and ID numbers read aloud are flagged automatically as they're found — you don't wait for the whole file to finish before you can start reviewing.

3

Click any word to redact a name — or anything else

Names aren't found automatically — nobody can honestly promise that. Instead, click a word (or drag across several) and choose Bleep, Mute, or "redact every occurrence." Add a name or phrase to a custom term list once, and it's flagged everywhere it's spoken, including later files.

4

Listen, then export a checked file

Every redaction gets a preview so you hear exactly what's being removed before you export. After export, the finished file is automatically checked to confirm each redacted part is actually silent or bleeped — not just trusted.

Bleep or mute — your call, per redaction

Mute — silences the redacted span completely. Clean and simple; a listener just hears a gap.
Bleep — replaces the span with the classic tone, so it's obvious something was intentionally removed rather than a recording glitch.

Set the mode per redaction, or change a whole group of matches at once. Both are previewed by ear before you ever export.

Your recording never leaves this device

  • Transcription, review, redaction, and export all run locally — nothing is ever uploaded
  • Disconnect your internet to test: once the page has loaded, redacting a recording keeps working — that's the proof nothing needed the network
  • Nothing is saved between visits — close the tab and the recording, transcript, and flags are gone
  • File metadata — recording-app tags, GPS, embedded titles — is stripped from the export by default

Trust, not a promise

  • Listen before you export: every redaction has a play button, so you hear what's being removed instead of trusting a timestamp
  • A check before you export unheard spans: if you try to export with redactions you haven't listened to, you'll be asked to confirm first
  • A check after export, too: the finished file is automatically re-examined to confirm every redacted part is actually silent or bleeped — if something looks wrong, the export is held back and shown to you instead of handed over
  • An optional log: download a record of what was redacted (times, type, and a count) without the sensitive words themselves, unless you explicitly ask to include them

Built for work where a cloud upload isn't an option

Clinics & telehealth

Redact patient names and details from therapy or telehealth recordings before sharing with a transcription service, a supervisor, or a training set — no Business Associate Agreement needed, because nothing leaves your device.

Law firms & paralegals

Prepare audio exhibits without exposing privileged conversations or third-party details — redact a client call or deposition recording before it enters the record.

Call centers & QA teams

Scrub card numbers and account details read aloud on a support call before a recording is stored or reviewed — the PCI-DSS pressure, handled without a vendor contract.

Researchers

Anonymize interview audio for IRB compliance before archiving or sharing a qualitative dataset — a participant's name is gone before the file ever leaves your laptop.

Journalists & podcasters

Protect a source's identity before publication or handoff — bleep a name or a location without re-recording the whole segment, and keep the raw file off any server in the process.

Frequently Asked Questions

How do I bleep out a word in a recording? +
Drop in your recording and it's transcribed right there on your device. Click any word in the transcript — or drag across several — and choose Bleep or Mute from the popup. Every redaction gets its own preview button, so you can listen to exactly what will be removed before you export the finished file.
Is this HIPAA compliant? +
Nothing about your recording ever leaves your device — there's no upload, no server, and no third party involved, so there's nothing to sign a Business Associate Agreement about. You can disconnect your internet after the page loads and redacting a recording still works, start to finish.
Can it find names automatically? +
Not automatically — recognizing a spoken name reliably is a much harder problem than recognizing a phone number or an email address, so we don't claim it does. What it does find automatically as the transcript comes in: phone numbers, card and bank numbers, emails, and ID numbers read aloud. For names, click any occurrence in the transcript and choose "Redact all occurrences," or add the name to a custom term list so every mention is flagged the moment it's spoken.
Why is my export limited on my phone? +
Phone browsers cap how much memory one tab can use, and rendering audio needs to hold the source and finished file in memory at the same time. On a phone we warn above 30 minutes of audio and stop at 90 minutes or 200 MB — past that, a computer will handle it more reliably than crashing partway through. On a computer the ceiling is much higher: a warning above 2 hours or 300 MB, a stop above 4 hours or 1 GB.
What audio formats are supported? +
Most common recording formats, plus video files with an audio track — we'll read the audio out of the video for you. Export is WAV (lossless — the safer choice for court or compliance use) or MP3 (smaller, universal). Video output isn't available yet: you'll get back the redacted audio track, not a video file.
Does it work offline? +
Yes. After the page loads once, disconnect your internet and keep working — transcribing, flagging, redacting, and exporting all happen locally, and nothing is ever sent anywhere.
What's the difference between bleep and mute? +
Mute silences the redacted span completely. Bleep replaces it with the classic tone, so a listener can hear that something was intentionally removed rather than wondering if the recording just cut out. You can set the mode per redaction, or change a whole group at once in the review list.
