Best Offline Transcription Apps for Mac & iPhone (2026): An Honest Buyer's Guide

The first question is not "which app"

Speech-to-text tools split along one architectural line: whether your audio is processed on hardware you own or on a vendor's servers. Everything downstream follows from that choice — the price model, the privacy posture, the minute caps, what happens on a plane — so make it first and the rest of the decision gets small.

Cloud buys you two real things: captions that appear live while someone is speaking, and a shared workspace your colleagues can search and comment in. It costs you three: your audio is uploaded and subject to a retention policy you have to go read, the meter is running (per-minute caps exist because compute is being spent on somebody else's servers), and the subscription renews whether you transcribed anything that month or not.

Local runs on the silicon you already paid for. There is no per-minute cap because there is no meter, no account because there is nothing to log into, and no retention policy to read because no copy of your audio exists anywhere to retain. It keeps working on a flight, in a hospital, inside a company that blocks outbound traffic. It does not automatically mean better accuracy — frontier cloud models are strong, and the honest comparison is in the FAQ below — but on Apple Silicon the open models are close enough that for most recordings the difference is noise. If you typed "offline" into a search box to get here, you have already made this choice. The rest of this page is about the local half of the field.

The local race: MacWhisper or Whisper Notes

Once you have decided the audio stays on the machine, the shortlist on Apple platforms is two apps. Both run the same families of open speech models, both are sold once instead of rented, and both pass the airplane-mode test at the bottom of this page. They differ in temperament, not in principle — one is a Swiss Army knife, the other is a pen.

MacWhisper — every feature a transcription app can have

MacWhisper's free tier covers basic transcription of the common audio and video formats in 100+ languages, with plain-text and SRT/VTT export, microphone recording and system-wide dictation. The Pro license — a one-time €64 with lifetime updates, stated on MacWhisper's own site — opens out into a genuine workstation: automatic speaker recognition, batch queues, watched folders, YouTube and media-URL transcription, meeting recording across Zoom, Teams, Webex, Skype, Chime and Discord, subtitle translation, per-speaker podcast files, .docx/.pdf/.md/.html export, a CLI, and integrations with Notion, Obsidian and Zapier. If a transcription feature exists, MacWhisper has probably shipped it — the right buy if you want every option under one roof, and the reason to look at Whisper Notes if you would rather the tool stayed simple.

The cost of that breadth is the shape of the tool: it is dense, it is Mac-only, and there is no phone app, so a recording made on your iPhone has to reach the Mac before anything can happen to it. If you enjoy a cockpit — many professionals do — none of that is a complaint. Our feature-by-feature comparison is at Whisper Notes vs MacWhisper.

Whisper Notes — three jobs, done cleanly, on both your devices

Whisper Notes concentrates on the three things people actually do with speech, and keeps everything around them minimal. Voice typing: hold Fn and speak, and the words are typed into whatever app has focus — Slack, an editor, a terminal (Direct Download build; Apple's rules keep the required text-insertion API out of App Store builds). Meeting transcription: system audio plus microphone on both Mac channels, no bot in the call; the Direct Download build detects Zoom, Teams and Google Meet calls and starts recording by itself, then writes the summary and action items locally with Gemma 4 — no API key, no cloud call. File transcription: three engines on every channel — Parakeet V3, Whisper, SenseVoice — covering 101 languages, with Speaker Labels computed on-device that tag an hour of audio in about 15 seconds.

And it is the only app on this shortlist that gives the iPhone the full toolset — recording, file import, folders, engine choice and Speaker Labels, all running on the phone itself — with one $6.99 App Store purchase covering both the iPhone app and the Mac App Store version. The interface stays out of the way: record, read, export, done.

So choose by temperament. If you want every option and enjoy a dense tool, buy MacWhisper. If you want the tool to disappear — three jobs done well, a clean screen, the same app in your pocket — buy Whisper Notes. Both answers keep your audio at home; neither uploads a byte.

Job 1: Voice typing into the cursor

This is the workflow where you hold a key, speak a sentence, release, and the text lands in whatever app has focus. It is the most demanding job on this page: the tool has to be fast enough that you stop noticing it, and it has to insert text into apps it does not control.

Whisper Notes does this natively on the Mac — hold Fn, speak, release — using the same local engines that transcribe your recordings, with nothing to configure and no per-app setup. It ships in the Direct Download build; the App Store build cannot include it, because Apple's sandbox rules keep out the accessibility API that types into other apps — the story behind why the Mac app left the App Store. The mechanics are written up in Mac system-wide dictation with Whisper.

The dictation specialists: Superwhisper and VoiceInk

Two apps treat dictation not as a feature but as the entire product, and if dictation is your whole working day, they earn the look. Superwhisper's "modes" system reshapes the raw transcript with a prompt — into an email, a commit message, a bug report — and nobody else has matched it, though that is also where the cloud enters: the design is hybrid, local models by default, with several accuracy and rewriting features routing your audio or text through a cloud provider, so "local" depends on which mode you picked. It runs on macOS, Windows and iOS, with a free tier that does not expire and a lifetime license listed at $249.99 on its own site, the highest price on this page. VoiceInk covers the same loop on Apple Silicon Macs for a $29 one-time license (more for multiple Macs), developed in public on GitHub — a privacy claim you can check by reading the source. The longer side-by-side is on our Superwhisper alternative page.

The decision rule is workload. If dictation is your entire job and prompt-driven rewriting is the point, buy the specialist. If voice typing is one of several things you do — alongside meetings, recordings and files from your phone — Whisper Notes does it inside the app that already handles the rest: one tool, one payment, one privacy model, local without conditions.

Apple Dictation — free, already installed, genuinely fine

Before paying anyone, try the dictation that ships with macOS and iOS. On modern hardware it runs on-device for many languages, it is system-wide, and for short messages the gap to a paid tool is smaller than the internet suggests. Where it falls down is long-form: punctuation discipline, technical vocabulary, and the absence of any cleanup pass. If you dictate a paragraph and then spend a minute fixing it, that is the moment a paid tool starts paying for itself.

Job 2: Transcribing a file you already have

Here the constraints invert. Nothing is real-time; you have an MP3, an M4A or an MP4 and you want text out of it. What separates the tools is where the file is, what language is in it, and how much of the surrounding work — speaker labels, formats, batch — the app does for you.

Whisper Notes — files on either device, with the engine matched to the language

If the recording is on your iPhone, the decision is short: MacWhisper and Buzz have no phone app. Whisper Notes records and transcribes on the iPhone itself (iOS 18 or later, iPhone 12 or newer recommended), imports from Files and Voice Memos including video, and one $6.99 App Store purchase covers both the iPhone app and the Mac App Store version — so the phone is not a capture device for some other tool, it is the tool.

If the audio is Chinese, Japanese, Korean or Cantonese, the engine matters more than the app. Whisper is not the strongest model for CJK, and most tools on this page only run Whisper. Whisper Notes ships SenseVoice alongside Whisper and Parakeet V3 on every channel — in our test it transcribed a 27-minute Chinese podcast in 13.83 seconds on an M4 Pro, with better punctuation than Whisper. The comparison is in SenseVoice vs Whisper for CJK, and the per-engine language table is at whispernotes.app/languages.

If you need to know who spoke, Speaker Labels run on-device on every channel — the iPhone app since 1.8.5, the Mac App Store build, and the Direct Download (DMG) build since 1.5.1 — labeling an hour of audio in about 15 seconds. Voiceprints are biometric data, which is a good reason to want that computation happening on your own chip; the model and its failure cases are described in on-device speaker diarization. Of the other local tools here, only MacWhisper's Pro tier also does speaker recognition; Aiko and Apple's built-ins do not.

On raw English throughput the field is closer than any vendor wants to admit, because everyone runs the same open models. For reference: Parakeet V3 transcribed 35 minutes of audio in 18 seconds on an M4 Pro in the benchmark runs we published — numbers you can reproduce, and which say more about the models than about the apps wrapping them. If you prefer a terminal to a window, the Direct Download build ships a CLI and an MCP server from 1.5.5, so scripts and AI assistants can transcribe and search locally.

MacWhisper — the deepest Mac-only file workflow

If files arrive on your Mac in volume — a podcast back-catalogue, a folder of interviews — MacWhisper Pro is built exactly for that: batch queues, watched folders that transcribe whatever lands in them, YouTube and media-URL input, and export into Notion, Obsidian and office formats. That workstation depth is real — and it is deliberately not where our depth went: ours went into the iPhone app, the CJK engines and on-device Speaker Labels instead. So the split is the one from the shortlist above: files pile up on a Mac, MacWhisper; files start on a phone, or the audio is CJK, or you want the same app at both ends of the cable, Whisper Notes.

Buzz — free, open source, and the answer on Windows and Linux

Buzz is an MIT-licensed desktop app that runs Whisper locally on macOS, Windows and Linux, with GPU acceleration, folder watching, TXT/SRT/VTT export and a CLI. It wins two situations outright. Budget: free with no per-minute cap beats every paid tool on this page if money is the binding constraint. Platform: we have no Windows or Android app and are not building one, so on Windows our recommendation is Buzz or a command-line tool like faster-whisper — that recommendation has its own page on this site, because sending people to the right tool beats pretending. The trade is polish: Buzz is a utility rather than a product, and it shows in the interface and the setup. On an Apple device, with a few dollars of budget, a purpose-built app is the nicer thing to use every day.

Aiko — the simplest one-shot transcription

Aiko does one thing: drop in audio or video, get an on-device Whisper transcription back, exportable as subtitles. It is a $24 one-time Universal Purchase covering iPhone, iPad, Mac and Vision Pro, and nothing leaves the device. Its limits are its design: no speaker identification, no choice of engine, no in-app editing — you export and fix the text elsewhere. If your need is "occasionally turn a recording into text with zero configuration", Aiko is a clean answer. The moment you need to know who spoke, pick a stronger engine for your language, or edit the transcript where it lives, you have outgrown it — and that is precisely the gap Whisper Notes occupies at a comparable price.

Job 3: Capturing a live meeting

Meetings are where the offline-versus-cloud choice stops being philosophical. A meeting has other people in it, and the honest split is about what happens to the notes afterwards.

Otter and Notta win if the notes are a team artifact

If you want captions appearing live during the call, a searchable shared workspace, calendar integration that joins meetings for you, and a link you can send to someone who missed it — buy a cloud tool. Otter's Basic tier is free with 300 minutes a month and a 30-minute cap per conversation; Pro is $16.99 per user per month, or $8.33 per month billed annually. Notta is a close equivalent with strong real-time translation. No offline tool does any of that, and no amount of local-first engineering will change it: collaboration requires a server. What you accept in exchange is that the audio is uploaded, the minutes are metered, the subscription renews, and a bot may appear in the participant list. Our detailed take is on Whisper Notes vs Otter.ai and Notta alternatives.

Whisper Notes and MacWhisper win if the recording must not leave the machine

The other half of the market is meetings that cannot be uploaded: patient consultations, privileged legal calls, board and compensation discussions, unannounced product work, interviews where the source was promised the recording stays put. Here a local tool is not a preference, it is the requirement.

Whisper Notes records meetings from system audio plus microphone on both Mac channels, with no bot joining the call and nothing visible to the other participants. The Direct Download (DMG) build additionally detects Zoom, Teams and Google Meet calls and starts the recording for you — walk into the call, and the transcript is simply there afterwards, with Speaker Labels separating who said what and Gemma 4 writing the summary and action items on the machine, no API key, no cloud call. The Mac App Store version records manually, because Apple's rules keep the automatic detection out. The walkthrough is in offline meeting transcription on Mac. MacWhisper Pro also records meetings locally and covers a wider list of conferencing apps — Webex, Skype, Chime, Discord — so if your calls live in those, it may decide it for you.

One limitation applies across the offline field, and we would rather you learn it now than after buying: none of the polished consumer apps here produce live captions during the call. Whisper Notes transcribes after the recording stops, not while you speak. If someone in the room needs to read the words as they are said, you need a cloud service or a dedicated captioning product.

Try Apple's built-in tools first

Voice Memos will transcribe a recording at no cost — on a Mac with Apple silicon running macOS 15 or later, and on iPhone since iOS 18. Combined with system Dictation, that covers a real share of casual use, and any recommendation that skips past it is trying to sell you something.

Four things push people off it. Apple transcribes a limited list of languages, far short of the 101 that Whisper covers — the per-engine breakdown is on our languages page. There is no speaker separation. There is no real export — you select the text and copy it, rather than getting TXT, SRT or VTT out. And there is no batch: one recording at a time, made in Apple's app, so a folder of interview files is not a job it can do. If none of those four matter to you, stop reading and save your money.

Pick by constraint

How to verify any of these claims yourself

Every vendor on this page, us included, says the word "private". You do not have to take anyone's word for it. Five checks, none of which need a technical background:

1. The airplane-mode test. Turn on Airplane Mode, or switch off Wi-Fi and unplug Ethernet, then record something and transcribe it. If the transcript still appears at full speed, processing is local. If you get a spinner, an error, or a queued job that completes the moment you reconnect, it is not. Do this after the app has finished downloading its model — a genuinely local tool needs the network exactly once, to fetch model weights.
2. Read the App Store privacy label. On the App Store listing, scroll to App Privacy. "Data Not Collected" is a claim the developer makes to Apple, with consequences for lying. Compare it against what the marketing page says. Also check whether the app requires an account: if you must create a login to transcribe, something is leaving your device.
3. Watch the network. A firewall like Little Snitch or the open-source LuLu shows you every outbound connection an app attempts. Transcribe a file with it running. Update checks and license validation are normal and small; a sustained upload the size of your audio file is not.
4. Look for the minute cap. Pricing pages are an honest signal. Per-minute charges and monthly minute allowances exist because compute is being spent on somebody else's servers. A tool that runs on your hardware has no reason to meter you, so unlimited local transcription is the default, not a premium tier.
5. Check whether "local" means "local by default". Several good tools are hybrid: local models for speed, cloud models for accuracy or rewriting, chosen per mode. That is a reasonable design, but it means the privacy answer depends on your settings rather than on the app. Find the model picker, see which option is selected, and check whether any text-cleanup or summarization step calls out separately from the transcription step.

Run those five against us as readily as against anyone else. Whisper Notes has no accounts, no login, and no hybrid mode — there is nothing to configure to make it local, because there is no other way it runs. The airplane-mode test takes thirty seconds and is worth more than this paragraph.

Where Whisper Notes does not fit

For symmetry, the cases where you should buy something else:

• Windows or Android. There is no build and none is planned. Use Buzz or faster-whisper.
• Intel Macs. The Mac app requires Apple Silicon. MacWhisper and Buzz are the fallbacks.
• Live captioning. Transcription happens after the recording, not during it.
• Collaboration. No shared workspace, no comments, no cloud sync between your own devices. It is a single-user tool by construction — that is what "no server" means.
• Prompt-driven rewriting. Superwhisper's modes reshape what you said into an email or a commit message. We transcribe what you said and leave your words alone.

Everything else — voice typing on a Mac (Direct Download build), meetings that must stay private, files from a phone, CJK audio, knowing who spoke, paying once — is the shape this app was built for. The details are on the Whisper Notes homepage; if your situation is one of the five above instead, one of the tools on this page is a better use of your money, and we would rather you spent it there.
