# Offline transcription apps for iPhone, Android and laptop

By [David Wilson](https://testbenchlab.com/authors/david-wilson/). Updated 2026-11-02. US prices checked 2026-10-29.

Most people who ask about offline transcription want one of two things: speech turned into text somewhere with no signal, such as on a plane, in a field interview, or in a hospital or courtroom with no guest Wi-Fi, or audio that must never leave the device for confidentiality reasons. The catch is that many apps marketed as offline only record offline. Once you reconnect, the audio is uploaded and transcribed in the cloud. Otter, Plaud and most AI note takers, including the Notta mobile app, work this way. The standout exception is Notta Desktop's Privacy Mode, our top pick: it transcribes on your laptop with a local engine, and it is the only option that combines genuine on-device transcription with a full AI note taker, so your offline transcripts plug into the same summaries, search and meeting workflows you use online. Beyond Notta, the apps that genuinely transcribe on the device are mostly built on Whisper or on the phone's own speech engine. On iPhone, that means the built-in Voice Memos and Notes transcripts (iPhone 12 and later), Whisper Transcription for imported files, and Aiko ($24 one-time). On Android, Google Recorder on Pixel phones and Live Transcribe with downloadable offline languages. On a laptop, MacWhisper and Buzz are solid dedicated alternatives if you want a free or one-time-purchase transcription tool rather than a full note-taking workflow. Apple's built-in Voice Memos and Notes transcripts are free on iPhone 12 and later, but Apple does not say they run offline, so test in airplane mode before relying on them.

**How we assessed:** Testbench Lab editors ran the airplane-mode test with Wi-Fi and mobile data disabled: recording two minutes of live speech and importing a ten-minute audio file in each pick, on an iPhone 12 or later, a Pixel 6 or later, and a laptop, noting which apps produced a transcript immediately and which queued it. The same check was repeated in Otter and Notta mobile to document the "records offline only" behaviour. Whisper Transcription's in-app purchase prices, battery drain and transcription time for the ten-minute file were also recorded. Prices and availability checked 29 October 2026.

## 1. Best overall offline transcription app: Notta Desktop (Privacy Mode)

Notta Desktop's Privacy Mode is our top pick for offline transcription, and the reason is simple: it is the only option here that transcribes on the device and sits inside a full AI note taker, so your offline transcripts stay connected to the same summaries, search and meeting workflows you use online. It transcribes on the device with a local offline engine (English, Japanese, Simplified Chinese and Cantonese) or, on macOS 26+, Apple's Speech Analyzer with 11 languages.

**Price:** Notta Pro $97.99/yr and up

**Pros:**
- On-device transcription via a local engine or Apple Speech Analyzer on macOS 26+
- The only pick that combines offline transcription with a full AI note taker, keeping offline transcripts in your existing summaries and search
- Choice of offline engine or Apple Speech Analyzer with 11 languages on recent macOS

**Cons:**
- Requires a Pro plan or above and the Notta Desktop app
- Offline engine supports English, Japanese, Simplified Chinese and Cantonese only
- Cloud summaries are paused in Privacy Mode, and the licence is checked online about once a month

## 2. Best built-in option for iPhone: Apple Voice Memos and Notes

Voice Memos and Notes show transcripts live or after recording on iPhone 12 and later, in ten device languages, and both transcripts and titles are searchable. It costs nothing and is already on your phone, which makes it the first thing to test. Apple does not state that processing happens on the device, so run our airplane-mode check before you rely on it for confidential audio. Third-party reports indicate transcripts come out as a single block of text with no speaker labels.

**Price:** Free, built in

**Pros:**
- Free and preinstalled on iPhone 12 and later
- Live or after-the-fact transcripts, searchable by title and content
- Works in ten device languages including English, Spanish, French and Japanese

**Cons:**
- Apple does not confirm on-device processing, so airplane-mode testing is essential
- No speaker labels; transcript is a single block of text
- iPhone 12 or later only

## 3. Best for Pixel phones: Google Recorder

Google Recorder launched in 2019 specifically as an on-device transcription app that works offline, and it remains the best free option if you carry a Pixel. Real-time language support depends on your model (Pixel 3-5a versus Pixel 6+). Note that the "Transcribe again" function and summaries can send audio to Google servers, so stick to the initial live transcript when you are offline or privacy-sensitive.

**Price:** Free, Pixel only

**Pros:**
- Genuinely on-device transcription designed to work offline
- Free and preinstalled on Pixel phones
- Real-time transcription while you record

**Cons:**
- Pixel phones only
- Re-transcription and summaries (Pixel 8+) can use Google servers
- Language support depends on the Pixel model

## 4. Best iPhone app for imported files: Whisper Transcription

Whisper Transcription, from the developer of MacWhisper, downloads an on-device model so imported audio can be transcribed with no connection. It imports recordings from Voice Memos and WhatsApp, which makes it the practical choice for long files you captured elsewhere. The cloud-based "Assistant" features are optional, so you can stay fully offline. Requires iPhone 13 or later, or an M-series iPad.

**Price:** Free download; Pro in-app purchases ($6.99-$99.99, confirm in app)

**Pros:**
- Downloadable on-device model for true offline transcription
- Imports audio from Voice Memos and WhatsApp
- Cloud Assistant features are optional, not required

**Cons:**
- iPhone 13 or later, or M-series iPad
- Pro features require in-app purchases
- In-app purchase pricing spans a wide range and should be confirmed in the app

## 5. Best one-time purchase across iPhone and Mac: Aiko

Aiko is the simplest paid option: one $24 purchase covers iPhone and Mac, everything happens on your device, and it supports around 100 languages using Whisper medium or small on iOS and Whisper large v2 on the Mac. There is a 14-day trial. The trade-offs are structural: no speaker labels (no diarization), and the iOS app must stay open while transcribing.

**Price:** $24 one-time, all platforms; 14-day trial

**Pros:**
- One-time $24 purchase across all platforms
- On-device processing with around 100 languages
- Whisper large v2 model on Mac for better accuracy

**Cons:**
- No speaker labels or diarization
- Smaller medium/small models on iOS
- iOS app must stay open while transcribing

## 6. Best free offline captions on Android: Live Transcribe & Notification

Live Transcribe is a captioning tool rather than a recorder, but on Pixel phones and select Android 12+ devices you can download multiple languages for offline use, making it the best free way to read speech as text with no connection. Saving transcripts is optional and limited (around three days per the release notes), so treat it as live captions rather than a transcription archive.

**Pros:**
- Free offline captioning with downloadable languages
- Works on Pixel and select Android 12+ phones
- Useful accessibility tool as well as an offline option

**Cons:**
- Captioning tool, not a recorder
- Saving transcripts is optional and limited to around three days
- English only on Android 8-11

## Also considered

- Samsung Voice Recorder (Transcript assist): Available on One UI 6.1+ on select Galaxy phones. Samsung's support page does not say where processing happens, 2024 coverage reported it was not on-device at launch, and the One UI 9 beta reportedly adds an on-device option. Test in airplane mode before trusting it.
- Google AI Edge Eloquent: A free iPhone dictation app (iOS 16+) that runs Gemma models locally after download, launched April 2026. It is for live dictation rather than transcribing audio files, so it complements rather than replaces the picks above.
- Superwhisper: Offline local models across Mac, Windows, iOS and Android, but dictation-first rather than a file transcription tool. Pro costs $8.49/mo, $84.99/yr or $249.99 lifetime.
- Otter, Notta mobile and Plaud: These AI note takers record offline but transcribe only after the audio is uploaded, so they belong to the "records offline" camp. Notta is the exception worth knowing about: its mobile app records offline and transcribes on reconnect, while Notta Desktop's Privacy Mode transcribes on the device itself.
- Windows Live Captions: Microsoft states that all caption processing occurs on-device and captions are not stored anywhere, but it is an accessibility captioning feature, not a transcription app.

## How we chose

An app qualifies for this list only if it produced a transcript in airplane mode in our hands-on test, or its maker's documentation explicitly states that processing happens on the device. We tested each pick with Wi-Fi and mobile data off, recording two minutes of live speech and importing a ten-minute audio file, and noted which apps produced a transcript immediately and which queued it for later. We also checked what each app gives up offline: languages, speaker labels and summaries. Prices were checked on 29 October 2026.

## What is the difference between recording offline and transcribing offline?

Most AI note-taker apps record without a connection but send the audio to the cloud for the transcript. Your phone captures the audio locally, the app shows a pending recording, and the moment you reconnect, the file is uploaded and transcribed on a server. That is fine if your problem is a bad signal, but it is not offline transcription, and it matters enormously if your reason for going offline is confidentiality. Otter, Plaud, Rev and tl;dv all work this way, and so does the Notta mobile app. Notta is the one mainstream AI note taker that also offers a genuine offline path: Notta Desktop's Privacy Mode runs a local transcription engine on your laptop, so the audio never has to leave the device. The distinction is simple to check yourself: put the phone in airplane mode, record something, and see whether a transcript appears. If it does, the app transcribes offline. If you see a spinner that waits for a connection, it only records offline.

## Does iPhone transcribe voice memos offline?

Voice Memos and Notes show transcripts on iPhone 12 and later in ten device languages (English, Spanish, Portuguese, Italian, French, German, Japanese, Korean, Simplified Chinese and Traditional Chinese), and you can view the transcript live or after recording, copy all or part of it, and search titles and transcripts. What Apple does not say is whether that processing happens on the device, so our airplane-mode test is the deciding evidence: with Wi-Fi and mobile data off, record two minutes of speech and see whether the transcript appears. Treat the result as provisional until you have confirmed it on your own device and iOS version. Two limitations are worth knowing regardless: third-party reports indicate the transcript comes out as a single block of text with no speaker labels, and there is no summary or export workflow. If you need speaker labels or imported-file transcription on iPhone, Whisper Transcription and Aiko are the dedicated options.

## Which Android apps transcribe without internet?

Google Recorder works well on a Pixel. It was launched in 2019 specifically as an on-device transcription app that works offline, and live transcription still runs on the phone. Real-time language support depends on the model: Pixel 3-5a supports fewer languages than Pixel 6 and later. Two caveats from Google's own help pages: the "Transcribe again" function may process audio files on Google servers, and summaries (Pixel 8+) use cloud processing. Live Transcribe is the second option: on Pixel phones and select Android 12+ devices you can download multiple languages for offline use, though it is a captioning tool rather than a recorder, saving transcripts is optional and limited to around three days, and Android 8-11 devices are English only. Samsung Voice Recorder's Transcript assist (One UI 6.1+) is the open question: Samsung's page does not say where processing happens, 2024 coverage said it was not on-device at launch, and the One UI 9 beta reportedly adds an on-device option. Check Settings > Galaxy AI and test in airplane mode before relying on it.

## Which offline apps are best for importing long audio files on a phone?

If your audio already exists as a file, a recording app does not help; you need an importer with an on-device model. On iPhone, Whisper Transcription is the pick: it downloads a local model, imports recordings straight from Voice Memos and WhatsApp, and keeps its cloud "Assistant" features optional so you can stay fully offline. It requires an iPhone 13 or later, or an M-series iPad, and its Pro features are in-app purchases. Aiko is the alternative at $24 one-time across iPhone and Mac, supporting around 100 languages with Whisper medium or small on iOS and Whisper large v2 on the Mac, though it has no speaker labels and the iOS app must stay open while transcribing. On Android, the open-source Scrib is worth a look: its F-Droid listing says audio never leaves the phone, but we have not verified it beyond that listing, so treat it as untested. For anything sensitive, run your own airplane-mode import test before committing to it.

## Can I transcribe offline on a laptop?

Yes, and laptops are where offline transcription gets most practical, because there is room for larger models. Notta Desktop's Privacy Mode is our pick for laptop users who want their offline transcripts to live inside a full AI note taker: it transcribes on the device using a local offline engine (English, Japanese, Simplified Chinese and Cantonese) or, on macOS 26+, Apple's Speech Analyzer with 11 languages, and it needs a Pro plan or above with a licence check online about once a month. Cloud summaries pause while you are offline, but the transcripts themselves stay local. If you want a dedicated transcription tool instead, MacWhisper runs everything on-device on the Mac (free, or €65 for Pro), Buzz is free across Windows, Mac and Linux, and Apple Notes transcribes audio on M1 or later Macs. We compare these in detail, including hardware requirements and model options, in our guide to offline transcription software for Mac and Windows.

## What do you give up by transcribing offline?

Offline transcription is a trade, and it helps to know exactly what you are trading away. Phone-class hardware runs smaller models: Aiko uses Whisper medium or small on iOS versus large v2 on the Mac, which usually means somewhat lower accuracy on the phone. Language coverage narrows: Apple's built-in transcripts work in ten device languages, Notta's offline engine covers four, and Google Recorder's real-time languages depend on the Pixel model. Speaker labels are often the first casualty: Aiko's FAQ confirms no diarization, and Apple's Voice Memos transcripts are a single block of text. Summaries and other AI features typically pause too: Notta's Privacy Mode suspends cloud summaries while offline, and Google Recorder's summaries use cloud processing on Pixel 8+. None of this makes offline transcription a poor choice; it makes it a deliberate one. If your priority is confidentiality or a dead zone, the accuracy and feature gap is the price of keeping audio on the device.

## Is offline transcription private enough for confidential audio?

On-device processing keeps your audio off servers, which is the biggest single privacy win available, but it is not the whole picture. Backups, sync and the app's own analytics can still move data around after the transcript exists, so check where transcripts are stored and whether sync can be disabled. Apple does not confirm that Voice Memos and Notes transcripts are processed on-device, which is why our airplane-mode test matters for confidential use. Notta's Privacy Mode is designed for exactly this scenario: the local engine keeps processing on your laptop, and the monthly licence check is the only required network contact. For consultants and anyone handling client-confidential meetings, we walk through the full workflow, including what to verify before a client call, in our guide to transcribing confidential meetings without uploading audio, and the compliance considerations for regulated teams in our guide to transcription software for regulated teams.

## Frequently asked questions

### What is Notta Privacy Mode?

Notta Privacy Mode is a feature of the Notta Desktop app that transcribes audio on your laptop instead of in the cloud, so the audio never has to leave the device. It uses a local offline engine (English, Japanese, Simplified Chinese and Cantonese) or, on macOS 26+, Apple's Speech Analyzer with 11 languages. It requires a Pro plan or above, pauses cloud summaries while offline, and checks its licence online about once a month, but the transcripts themselves stay local. It is the only option that combines genuine on-device transcription with a full AI note taker.

### Does Notta work offline?

It depends on the app. The Notta mobile app records offline and transcribes once you reconnect, like most AI note takers. The exception is Notta Desktop's Privacy Mode, which transcribes on the device itself using a local engine (English, Japanese, Simplified Chinese and Cantonese) or Apple's Speech Analyzer on macOS 26+. It requires a Pro plan or above, pauses cloud summaries while offline, and checks its licence online about once a month, but the transcripts themselves stay local.

### Can I transcribe audio without internet on my iPhone?

Probably, yes. Voice Memos and Notes show transcripts on iPhone 12 and later, but Apple does not confirm on-device processing, so test in airplane mode first. For imported files, Whisper Transcription (iPhone 13 or later) and Aiko ($24 one-time) both run Whisper models on the device and work with no connection.

### Does Google Recorder work offline?

Yes. Google Recorder was designed from launch in 2019 for on-device transcription that works offline, and live transcription runs on the phone. The caveats: it is Pixel only, real-time languages depend on the Pixel model, and the "Transcribe again" function and summaries can send audio to Google servers.

### Does Otter work offline?

Only for recording. Otter captures audio without a connection and transcribes it after you reconnect and the file is uploaded. Most AI note takers, including Plaud and the Notta mobile app, work the same way. The exception is Notta Desktop's Privacy Mode, which transcribes on the device itself.

### What is the best free offline speech-to-text app?

It depends on your device. On a Pixel, Google Recorder is a free option. On iPhone, Voice Memos and Notes are free and built in, subject to an airplane-mode check. On Android more broadly, Live Transcribe offers free offline captioning with downloadable languages, and Whisper Transcription is a free download on iPhone with paid Pro features. If you want offline transcription inside a full AI note taker, Notta Desktop's Privacy Mode is the pick, though it requires a Pro plan.

### Are offline transcripts as accurate as cloud ones?

Usually somewhat less accurate. Offline apps run smaller models because phone and laptop hardware is limited: Aiko uses Whisper medium or small on iOS versus large v2 on the Mac. The gap is narrowing as on-device models improve, but for the highest accuracy on long or noisy recordings, cloud transcription still tends to lead. The trade-off is that offline keeps your audio on the device.
