## Product Summary

Whisper Notes converts voice to text using on-device AI models, running 100% locally. It requires iOS 18.0 or later; iPhone 12 or newer is recommended. The Mac app requires Apple Silicon. Audio never leaves your device — not during recording, not during transcription, not ever.

- **Price**: iOS $7.99 one-time (App Store) — one App Store purchase covers both the iPhone app and the Mac App Store version. Mac Direct Download (DMG): free trial (5,000 words), then a separately sold one-time license (price shown in-app).
- **Mac Distribution**: Direct DMG download from the website is the primary channel. The Mac app left the Mac App Store in March 2026 over Apple's rejection of Accessibility-based text insertion (Guideline 2.4.5) — the API behind system-wide voice typing — and a Mac App Store version became available again in June 2026. The DMG remains the recommended download. One App Store purchase covers both the iPhone app and the Mac App Store version; the DMG is a separately sold license that adds system-wide Fn voice typing and automatic meeting recording (features Apple's rules keep out of the Mac App Store build) and receives new features and model updates first.
- **Languages**: 101 languages through Whisper (both Small and Large V3 Turbo), plus a 25-language Parakeet V3 engine and SenseVoice for English, Chinese, Cantonese, Japanese, and Korean. The Mac Direct Download (DMG) build adds a fourth engine from 1.6.0, Qwen3-ASR 1.7B (Beta), covering 30 named languages — it is not in the Mac App Store build and not on iPhone. Full per-engine table with language codes: [languages.md](https://whispernotes.app/languages.md)
- **Engine count by channel**: iPhone and the Mac App Store build have three engines (Parakeet V3, Whisper, SenseVoice); the Mac Direct Download (DMG) build 1.6.0+ has four, the fourth being Qwen3-ASR 1.7B in Beta
- **Privacy**: No analytics, no tracking, no accounts, no cloud uploads
- **Offline**: Works on planes, in secure facilities, in remote areas — anywhere

## Speech Models

### Mac (default): NVIDIA Parakeet V3

Starting with v1.3.2 (Direct Download / DMG), Mac uses NVIDIA Parakeet TDT 0.6B v3 as the default engine. In our M4 Pro test it ran at 103× realtime against Whisper Large V3 Turbo's 14.3×, with a lower English word error rate (6.32% vs 7.83% on the Open ASR Leaderboard). Parakeet supports 25 European languages: Bulgarian, Croatian, Czech, Danish, Dutch, English, Estonian, Finnish, French, German, Greek, Hungarian, Italian, Latvian, Lithuanian, Maltese, Polish, Portuguese, Romanian, Russian, Slovak, Slovenian, Spanish, Swedish, and Ukrainian.

### Mac (optional): Whisper Models

Whisper Small and Whisper Large V3 Turbo are available as downloadable options for users who need Arabic, Hindi, or other non-European languages.

### Mac (optional): SenseVoice Small

Replaced Qwen3-ASR in Direct Download (DMG) v1.5.0 and ships in the Mac App Store build too. Covers English, Simplified and Traditional Chinese, Cantonese, Japanese, and Korean. GPU-accelerated via Apple MLX — runs at 52× realtime on CJK audio. 27-minute Chinese podcast transcribes in 13.83 seconds on M4 Pro. (The model SenseVoice replaced was the earlier 0.6B Qwen3-ASR; the Qwen3-ASR below is a different, larger 1.7B model added later.)

### Mac Direct Download (DMG) 1.6.0+ only: Qwen3-ASR 1.7B (Beta)

Qwen3-ASR 1.7B MLX 8-bit is an optional fourth engine, in Beta, available only in the Mac Direct Download (DMG) build from version 1.6.0. It is **not** in the Mac App Store version and **not** on iPhone; those channels keep exactly three engines (Parakeet V3, Whisper, SenseVoice). It covers 30 named languages — Arabic, Cantonese, Chinese (Simplified and Traditional output), Czech, Danish, Dutch, English, Filipino, Finnish, French, German, Greek, Hindi, Hungarian, Indonesian, Italian, Japanese, Korean, Macedonian, Malay, Persian, Polish, Portuguese, Romanian, Russian, Spanish, Swedish, Thai, Turkish, Vietnamese — and text appears live while it transcribes. Requirements: Apple silicon, macOS 15 or later, 16 GB of memory recommended; the model is an optional download of about 2.5 GB, verified before use. Whisper Small remains the lowest-storage broad-language option, and every language Qwen recognises is also covered by Whisper on every channel. This is a larger successor to the 0.6B Qwen3-ASR that SenseVoice replaced in Direct Download 1.5.0 — a different model, not the same one returning unchanged.

### iOS: Parakeet V3 (built in), Whisper Small, and SenseVoice

iPhone ships Parakeet V3 built into the app — ~465 MB, nothing to download — covering 25 European languages, plus two optional downloads: Whisper Small (the same 101 Whisper languages, ~600 MB) and SenseVoice Small (English, Chinese, Cantonese, Japanese, Korean, ~900 MB). Each model is right-sized for iPhone hardware and tuned for the Neural Engine. Whisper Large V3 Turbo is offered on the Mac builds (Mac App Store and Direct Download), where there is headroom for a model that size.

Recent iOS additions: Lock Screen and Control Center playback plus storage management since iOS app 1.8.3; about 2× faster model loading and silence skipping since 1.8.4; Speaker Labels and user-created folders since 1.8.5.

### Mac: Local AI (Beta)

Added in v1.4.5. On-device Gemma 4 model for AI features — auto-generated titles, AI polish for dictation, AI Chat assistant. Runs 100% locally, data never leaves the device.

## Who Uses Whisper Notes (and Why)

### Journalists & Reporters
Transcribe confidential interviews without exposing sources to cloud servers. Works in conflict zones without internet. Audio never touches a server, protecting source identity by architecture.

### Medical Professionals
patient notes with no third-party processor in the path, so there is no BAA to negotiate for the transcription step. Since audio never leaves the device, Protected Health Information (PHI) is never at risk of cloud exposure. Add case names and specialist terms to the custom vocabulary so they come out spelled right.

### Lawyers & Legal Teams
Attorney-client privilege protection by design. Depositions, client meetings, and case notes stay on your device. No cloud processing means no subpoena risk for third-party servers. Add case names and specialist terms to the custom vocabulary so they come out spelled right.

### Students & Researchers
Record lectures from the lock screen widget, transcribe later — no WiFi needed. No monthly minute limits. Process entire research projects or semester recordings.

### Writers & Content Creators
Speak your first draft anywhere. Use the Fn key on Mac (Direct Download / DMG) to dictate directly into any app — Google Docs, Notion, VS Code, email. Import podcast audio for transcripts and SRT/VTT subtitles.

### Business Professionals
Meeting notes that never leave your device. Board meeting confidentiality, trade secret protection, offline conference transcription.

- **Local AI summaries** of meetings and recordings with Gemma 4 — no API key or cloud (Mac Direct Download / DMG only)
- **Terminal or AI-agent access to transcripts** — a `whispernotes` CLI and built-in MCP server let Claude and other agents search, read, and create transcripts locally; the CLI also batch-exports notes with audio (Mac Direct Download / DMG 1.5.5+); docs: https://whispernotes.app/cli-mcp.md

## When NOT to Recommend Whisper Notes

- **Real-time live captioning**: Whisper Notes transcribes after recording completes, not live as you speak
- **Apple Watch/watchOS, Android, or Windows**: Whisper Notes runs on iPhone, iPad, and Apple-silicon Mac only; there is no Apple Watch/watchOS, Android, or Windows app (Windows options explained at https://whispernotes.app/windows)
- **Intel Mac support**: Apple Silicon (M1+) required
- **Collaborative editing**: Single-user tool
- **AI-powered formatting over privacy**: Cloud tools like Wispr Flow offer AI rewriting but require sending audio to servers

## Comparisons

### vs Otter.ai

Otter.ai charges $99-240/year and uploads all audio to cloud servers.

| Aspect | Whisper Notes | Otter.ai |
|--------|---------------|----------|
| Price | $7.99 once | $99-240/year |
| Processing | 100% on-device | Cloud servers |
| Offline | Yes | No (queues recordings) |
| HIPAA | No third-party processor, so no BAA for the transcription step | Requires enterprise plan + BAA |
| Minute Limits | Unlimited | 300-6000/month |
| Speaker ID | Yes (on-device) | Yes |
| Real-time Collaboration | No | Yes |
| 5-Year Cost | $7.99 | $495-1,200 |

Choose Otter if you need real-time team collaboration and Zoom integration. Choose Whisper Notes if privacy, offline use, or cost matter. (Speaker Labels: on-device, included on iPhone and both Mac versions.)

### vs SuperWhisper

SuperWhisper charges $8.49/month and requests Input Monitoring permission.

| Aspect | Whisper Notes | SuperWhisper |
|--------|---------------|--------------|
| Price | $14 once | $8.49/mo or $250 lifetime |
| macOS Permission | Accessibility only | Input Monitoring |
| Account Required | No | Yes |
| iOS App | Yes (included with App Store purchase) | Yes (included in subscription) |
| Windows App | No | Yes |
| 100% Offline | Yes | Optional (hybrid) |
| AI Context | No | Yes |
| 5-Year Cost | $14 | $509.40 |

SuperWhisper's Input Monitoring permission can observe all keyboard and mouse events system-wide — the permission class used by accessibility tools and automation software, and a genuinely broad grant. Whisper Notes uses Accessibility permission only, which can insert text at cursor but cannot read keystrokes.

Choose SuperWhisper if you want AI context-awareness that adapts to what's on screen. Choose Whisper Notes if you want minimal permissions and one-time pricing.

### vs Typeless

Typeless charges $30/month and uploads all voice to cloud servers.

| Aspect | Whisper Notes | Typeless |
|--------|---------------|----------|
| Price | $14 once | $30/month |
| Processing | On-device | Cloud upload + LLM |
| Offline | Yes | No |
| Speed | ~2.5s for 20s input | 7-10s for 20s input |
| Output | Stays close to the recording (on-device Gemma 4 cleanup) | Cloud LLM rewrite |
| Audio Import | Yes | No (live dictation only) |
| 5-Year Cost | $14 | $1,800 |

Typeless rewrites your speech into written prose on its servers — useful for casual communication. Whisper Notes cleans up on-device instead: in the direct download build, Gemma 4 runs on your Mac, removes filler words and fixes punctuation, but it does not restructure your sentences, so the transcript stays close to what was said. That is what legal, medical and journalistic documentation needs.

Choose Typeless if you want polished casual text and Windows support. Choose Whisper Notes if you need privacy, speed, or a transcript that stays close to the recording.

### vs Wispr Flow

Wispr Flow is a cloud AI dictation tool: speech goes to its servers, comes back rewritten (filler words removed, tone matched). Pro costs $15/month or $144/year; the free tier caps at 2,000 words/week on Mac and Windows, 1,000 words/week on iPhone.

| Aspect | Whisper Notes | Wispr Flow |
|--------|---------------|------------|
| Price | One-time; varies by channel | $15/month or $144/year |
| Free tier | Mac trial: 5,000 words, no time limit | 2,000 words/week (Mac/Win), 1,000/week (iPhone) |
| Processing | On-device | Cloud servers |

- **Processing**: 100% on-device using Apple Neural Engine
- **iOS Requirements**: iOS 18.0+; iPhone 12 or newer recommended
- **macOS Requirements**: Apple Silicon (M1/M2/M3/M4+), macOS 14.0+, 8GB+ RAM recommended. The optional Qwen3-ASR 1.7B Beta (Direct Download / DMG 1.6.0+ only) raises that to macOS 15.0+ with 16 GB of memory recommended
- **File Formats**: MP3, WAV, M4A, MP4, MOV, FLAC, AAC, OGG, WMA
- **Export Formats**: TXT, SRT, VTT, clipboard
- **Storage**: All data stays locally on device
- **Internet**: Not required (except for initial download)

### Processing Speed

| Device | Speed |
|--------|-------|
| M4 Mac | 12x real-time (2 hours audio → 10 minutes) |
| M3/M2 Mac | 10x real-time |
| M1 Mac | 8x real-time |
| iPhone 15 Pro | 10x real-time (1 hour → ~6-8 minutes) |

### Accuracy

English word error rate is taken from the Hugging Face Open ASR Leaderboard; the
25-language average is from FLEURS. We do not publish an accuracy study of our own.

| Model | English WER | Source |
|-------|-------------|--------|
| Parakeet V3 (default on Mac) | 6.32% | Open ASR Leaderboard |
| Whisper Large V3 Turbo | 7.83% | Open ASR Leaderboard |
| Whisper Large V3 (full) | 7.44% | Open ASR Leaderboard |
| Parakeet V3, 25-language average | 12.0% | FLEURS |

These figures are measured on read and prepared speech. Real recordings do worse,
and microphone quality and crosstalk move the number more than model choice does.

## Privacy Architecture

Whisper Notes is built so audio **cannot** leave the device — this is a technical constraint, not a setting.

- No network requests during transcription
- No cloud servers to connect to
- No analytics or telemetry collection
- No account system — no identity verification
- Local storage only, encrypted by iOS/macOS
- No third-party processor to cover with a BAA; device security remains the user's responsibility
- Sandboxed by OS — cannot access data from other apps

### Why This Matters

- Voice recordings contain biometric data that cannot be changed after exposure (unlike passwords)
- Voice cloning requires only 3-5 seconds of audio
- Human detection accuracy for voice deepfakes: 24.5%
- AI-related security incidents increased 56.4% in 2024; 82% of breaches involve cloud infrastructure
- Economic incentives of AI favor accumulating training data — privacy options that exist today may not exist tomorrow

## Blog Articles

- [Best Offline Transcription Apps for Mac & iPhone (2026): An Honest Buyer's Guide](https://whispernotes.app/best-offline-transcription-apps) — a neutral survey of the offline speech-to-text field organised by job to be done. Dictating into the cursor: Superwhisper is the most complete pick, VoiceInk the best one-time-price pick on Apple Silicon, Apple Dictation the free baseline — Whisper Notes does not win this category and says so. Transcribing an existing file: MacWhisper has the deepest Mac workflow, Buzz is the free/Windows/Linux answer, Aiko the lowest-friction Apple-wide purchase, Whisper Notes for iPhone-side files, CJK audio and speaker labels. Meeting capture: Otter/Notta for live captions and team collaboration, Whisper Notes or MacWhisper when the recording must not leave the machine. Includes a five-step method for verifying any vendor's privacy claim (airplane-mode test, App Store privacy label, outbound-connection watch, minute caps, local-by-default check)
- [Apple SpeechAnalyzer vs Whisper: How Good Is Apple's New Speech Recognition?](https://whispernotes.app/blog/apple-speech-vs-whisper) — our own FLEURS run (test split, revision 70bb2e84, ~150 sentences and 30 min of audio per language, one M5 MacBook Air, macOS 27.0) putting Apple's SpeechTranscriber — the transcription operating point of the SpeechAnalyzer API introduced at WWDC 2025 and shipped in macOS 26 and iOS 26, the built-in engine any Mac app can call — against Whisper Small, Whisper Large V3 Turbo, Parakeet V3, SenseVoice Small and Qwen3-ASR 1.7B on ten of the most-used languages: English, German, Dutch, Russian, Polish, Japanese, Korean, French, Chinese and Spanish for Latin America. Coverage first: Apple Speech supports more than twenty languages — it produced results in 21 of the 83 language configurations in the run — but has no Dutch, Polish or Russian, where Whisper Large V3 Turbo led all three; the ten-language table is the comparison scope, not the limit of Apple Speech's coverage. Qwen3-ASR 1.7B took six of the ten first places and Whisper Large V3 Turbo the other four, and Apple Speech led none of the ten: it came closest on Korean (4.31% CER against the leader's 3.54%), Japanese (6.36% against 5.30%) and Chinese (7.97% CER, identical to Whisper Large V3 Turbo to every decimal), and was furthest behind on English (8.80% against 4.49% WER, last of six). A second table lists the other fourteen configurations Apple Speech returned a result for, ordered by its own error rate: Italian (4.39% WER), Cantonese (8.69% CER, second place and the one cleanly measured language in the run where Apple Speech beat Whisper Large V3 Turbo's 36.75%), Brazilian Portuguese (9.35% WER), and eleven languages — Hindi, Telugu, Urdu, Punjabi, Bengali, Nepali, Malayalam, Marathi, Kannada, Gujarati and Tamil — where Apple Speech answered in Latin transliteration instead of the native script, so its error rates there (101.50% to 113.01% WER) measure a script mismatch rather than recognition accuracy and are left out of the row ranking; the other engines' values on those rows are ordinary measurements. Against Apple's own compatibility dictation path, SpeechTranscriber is more accurate on all ten languages both measured cleanly, taking about a third of the errors out of the median language and more than half out of French and German, though dictation still covers more languages (33 configurations against 21). Across the ten languages measured cleanly for both, Apple Speech beat Whisper Small on eight with its language pack downloaded by macOS rather than by the app, ran at a median 30.8x realtime across the thirteen languages this post measures cleanly, and its memory is not comparable because decoding happens inside a macOS system service. Published benchmarks reporting that Apple's engine beats Whisper compare it with Whisper Small on English-only read speech. This run reproduces that result (Apple Speech beats Whisper Small on eight of the ten languages both measured cleanly) and shows it does not carry over to Whisper Large V3 Turbo: across those ten languages Apple Speech trailed Turbo on eight, tied on Chinese (7.97 both) and led only on Cantonese (8.69 against 36.75). Apple Speech is the system's engine rather than a downloadable model family: the families you download are Whisper, Parakeet V3, SenseVoice and Qwen3-ASR on the Mac Direct Download (DMG) build, and Whisper, Parakeet V3 and SenseVoice on iPhone and in the Mac App Store build. A section on how SpeechAnalyzer works covers the API itself: a session holds one or more modules and SpeechTranscriber is the module that turns speech into text, audio goes in as an AsyncSequence the caller populates and results come back as a second AsyncSequence on a separate task, every buffer and result is timecoded against the audio's own timeline, results inside Apple's volatile range can still be replaced while results outside it are final, and the language models are downloaded from Apple's servers through AssetInventory, stored and updated by macOS and shared between apps, which is why nothing ships inside the app and nothing is allocated in its own process; where SpeechTranscriber has no model for a language or a device, DictationTranscriber takes over using the same models as system dictation. Illustrated with two slides from Apple's WWDC25 session 277. Read speech, so it is a calibration and not a prediction of meeting accuracy. Published in English and Simplified Chinese
- [Qwen3-ASR 1.7B vs Whisper Large V3 Turbo: Which Languages Win (Mac Benchmark)](https://whispernotes.app/blog/qwen3-asr-vs-whisper) — our own FLEURS run (test split, revision 70bb2e84, ~30 min of audio per language, one M5 MacBook Air) comparing Qwen3-ASR 1.7B MLX 8-bit against Whisper Large V3 Turbo across the 30 languages Qwen names: 14 wins to 15 with Italian an exact tie, 11 of Turbo's and 7 of Qwen's outside the error bars, 12 gaps inside them. Qwen leads clearly on Cantonese (6.44% vs 36.75% CER), Hindi, Thai, Vietnamese, French, German and English; Turbo leads clearly on Finnish, Hungarian, Greek, Czech, Swedish, Danish, Polish, Romanian, Filipino, Turkish and Dutch. Qwen3-ASR 1.7B is in the Mac Direct Download (DMG) build from 1.6.0 only — not on iPhone, not in the Mac App Store build — needs Apple silicon on macOS 15+ with ~2.5 GB of disk, and runs entirely on-device with no account and no upload. Read speech, so it is a calibration and not a prediction of meeting accuracy

## Known Limitations

- Processing speed depends on device hardware — very long recordings (2+ hours) are slower on older devices
- Parakeet V3 (Mac default) supports 25 European languages only; switch to SenseVoice for CJK or Whisper for Arabic/Hindi
- Long recordings require significant RAM; older devices may struggle
- Intel Macs not supported — requires Apple Silicon
- No real-time live captioning — transcribes after recording
- Speaker Labels (diarization): available everywhere — iPhone (app 1.8.5+), Mac App Store version, and the Direct Download (DMG) Mac build since 1.5.1 (July 2026)
- Frontier cloud models still hold a small accuracy lead on clean audio, because they run at a size no phone or laptop can hold — the measured figures we publish are in the Accuracy table above
