Voice Rack

English · 中文版

Ask your recordings. Offline. Voice recorders, phone memos, meeting captures: scattered everywhere, named nothing. Point Voice Rack at them and minutes later every recording has a summary and tags you can filter, search and ask about. Transcription, search and answers run on your Mac; not one byte leaves it.

Get it on the Mac App Store

Free to download. Needs a Mac with Apple silicon and macOS 26.

Voice Rack library: recordings grouped by date with summaries and tags, and a meeting transcript with speaker names and timestamps
Every recording gets a summary and tags; a transcript keeps speakers and timestamps. All recordings shown on this page are synthetic demo files.

Pro · whole library

Ask your whole library

"Which meeting discussed the budget? What was decided?" Ask across every recording at once. Answers cite the source file and the second it was said; click to jump there and listen. Ask in one language and still match recordings in another. New in 1.1: narrow a question to one source folder, group or tag. Right-click it in the sidebar, or type @ or # while you ask.

Ask the whole library: one question answered from several recordings, with the matched clips and timestamps listed below
One question, answered from several recordings, with the clips it drew on.

Free · per recording

Or talk to one recording

Open a recording and ask follow-up questions with context. Every answer carries a timestamp you can click to hear the source, so you check instead of trusting a summary. Long recordings switch to retrieval automatically, so a three-hour file answers as readily as a three-minute one.

Who said what

Speaker identification runs on your Mac. Name each speaker once and every line in the transcript follows.

A term book that learns

Names and jargon get transcribed wrong once; fix them once and new transcripts get them right. It can even learn terms from your own documents. With Pro, apply a correction back across every recording you already have.

Free · per recording

Speaks your languages

Transcribes 90+ languages; measured end to end in English, Chinese (Mandarin and Cantonese), Spanish, French, German, Dutch, Italian, Japanese, Korean and Russian. A lecture that switches between two languages stays bilingual. Ask in your language and the answer comes back in it, even when the recording speaks another. Summaries and tags follow the app's display language; transcripts stay in the recording's own language.

A library in seconds

Import copies recordings into your library folder and leaves the originals where they were, or point Voice Rack at folders you already keep. Recordings are organized by their metadata first; transcription runs in the background, and if you quit halfway it picks up where it left off. Keyword search and tag filters cover the whole library, free.

Summaries, with or without timestamps

Every point in a summary carries the timestamp it came from, so you can listen back. When you only want the text, switch timestamps off: the summary on screen, Copy Summary and exports all follow. Points with no source keep their "unverified" mark either way.

Free · Pro exports a whole list

Seven export formats

SRT and VTT subtitles, Markdown, CSV, HTML, TXT and JSON. Recordings export as the original file or as M4A. With Pro, export everything in the current list in one step. New in 1.1.1: Copy This Page puts the tab you are on (Original, Cleaned, Summary, Translation or To-dos) on the clipboard, with or without timestamps.

Honest by design

Uncertain passages are flagged for a three-second listen instead of dressed up. When the transcript has no answer, it says so. Auto-extracted tags stay suggestions until you confirm them, and cleaned-up transcripts keep numbers exactly as spoken: anything the model cannot carry over verbatim is kept in the original and flagged.

Offline is the architecture

The speech and language models ship inside the app, and the app has no network permission at all: no account, no sign-in, nothing to activate. That is enforced by macOS rather than promised by us, and you can check it in ten seconds:

codesign -d --entitlements - "/Applications/Voice Rack.app"

The list has no network entitlement, so the sandbox refuses every outgoing connection. The one exception is one you choose: with Pro, you can let an AI assistant on your Mac search your library. See the privacy policy.

Privacy Policy

Frequently asked questions

Does anything leave my Mac?

No. Voice Rack has no network permission: recordings, transcripts, tags and answers are processed and stored on your Mac, and it works the same with Wi-Fi turned off. The one exception is one you choose yourself: with Pro you can let an AI assistant on your Mac search your library. See the privacy policy.

Which Macs does it run on?

A Mac with Apple silicon (M1 or later) and macOS 26 or later, with at least 8 GB of memory (16 GB recommended) and about 5 GB of disk space. Intel Macs are not supported. On an 8 GB Mac, summaries and answers are noticeably slower; transcription is not affected.

Which audio formats can I import?

MP3, M4A and AAC (including MP4 and M4B), Apple Lossless, FLAC, WAV (PCM, IMA-ADPCM and μ-law), AIFF, CAF, Ogg (Vorbis and Opus), and AAC-encoded 3GP, 3GA and 3G2 files from Android voice recorders.

macOS cannot decode WMA or proprietary recorder formats such as Olympus DSS/DS2 and WeChat SILK, so Voice Rack cannot read them either. They still appear in your library, greyed out with a note saying the format cannot be read; convert them to MP3, M4A or WAV first.

What can I export?

Transcripts export as TXT, Markdown, SRT and VTT subtitles, CSV, HTML and JSON. Recordings export as the original file or as M4A, which plays on phones, car stereos and messaging apps. MP3 export is not available, because macOS does not include an MP3 encoder.

How long does transcription take?

It depends on the Mac. Transcription works as a queue: import a batch, pause it, and resume later, even after quitting the app.

For reference: 2026-09-27, M5 Pro, build 1.0.0 (202609271012), a 126-minute recording transcribed in 2 min 46 s, single measurement.

Can it handle long recordings?

Yes. Long recordings switch automatically to retrieval, so a three-hour file can be asked about as readily as a three-minute one.

Can I ask across many recordings at once?

Yes, with Pro. Ask one recording what was decided, or ask the whole library a question that spans several conversations. Both modes answer with clickable timestamps that jump to the exact moment in the source audio.

How do I know an answer is right?

Every answer cites the recording and timestamp it came from, so you can listen to the source instead of trusting a summary. Auto-extracted tags stay suggestions until you confirm them, and cleaned-up transcripts keep numbers exactly as spoken: anything the model cannot carry over verbatim is kept in the original and flagged.

How much does it cost?

Everything you do on a single recording is free. Pro is a one-time purchase, with no subscription, that adds library-wide features such as asking across all recordings. You can try Pro free for 14 days.

Where do I get it?

From the Mac App Store. The download is free; Pro is an in-app purchase. It is available in every App Store region, including mainland China since 2026-10-28.
