oto is a privacy-first, offline-first voice-to-text transcription application for
macOS (with an iOS version coming soon). It lets users dictate up to 5x faster than typing, supports
100+ languages, and runs transcription entirely on-device: audio never leaves your
Mac. There is no account, no subscription, and no app telemetry.

================================================================================
KEY FEATURES
================================================================================

## Privacy & Security
- Offline-first transcription: all on-device AI engines run locally on your Mac
- Audio never leaves your device for transcription
- Zero app telemetry, analytics, or tracking
- No account creation required
- Optional cloud AI cleanup is OFF by default. If you turn it on, only transcript
  TEXT (never audio) is sent to the AI provider you configure.
- Privacy-friendly by design: there's no audio or transcript collection to protect

## Transcription Engines (all run locally)
oto ships with three on-device engines so you can pick the right one for the moment:
- **Whisper**: OpenAI's Whisper models. 100+ languages, can translate supported
  speech to English. Choose smaller models for speed or larger models for accuracy.
- **Parakeet v3**: A fast local engine for supported languages; solid accuracy with
  a lighter feel. Outputs text in the language you speak.
- **Apple SpeechAnalyzer**: Apple's on-device speech engine. Outputs text in the
  language you speak.

## Transcription Capabilities
- Voice-to-text as you speak, into any text field on macOS
- Automatic punctuation and formatting
- Smart hotkeys: map a key, dictate, and text auto-pastes at your cursor
- Transcription history
- Mix supported languages within a single recording (Whisper)

## Developer Tools: CLI and MCP Server (v2.2.0)
oto is scriptable. Both surfaces are enabled from Settings → Advanced and both keep
transcription fully on-device.

- **Command-line tool**: install the `oto` command from Settings → Advanced, then:
  - Transcribe a file: `oto transcribe < file.m4a`
  - Start and stop recordings from the terminal
  - Browse transcription history from the terminal
  - Results also land in the app's history, so terminal and app share one record.
- **MCP server (Model Context Protocol)**: Settings → Advanced provides a ready-to-paste
  config for Claude Desktop, Claude Code, Cursor, or any MCP client. Once connected,
  **AI assistants transcribe audio through oto fully on-device**: the assistant hands oto
  a file or asks for a recording, oto transcribes it locally on the Mac, and only the
  resulting text is returned. No cloud transcription API is involved and audio never
  leaves the machine.

This makes oto usable as the local transcription backend for AI agents, scripts, build
steps, and automation, with the same privacy properties as dictating by hotkey.

## Meeting Transcription (v2.2.0)
Long-form meeting recording captures two audio streams at once (your microphone and the
meeting audio) with echo cancellation, so running the call through your Mac's speakers
does not bleed the other side back into your own.

- The result is a two-sided (dual-stream) transcript: your side and the meeting side kept
  apart.
- IMPORTANT ACCURACY NOTE: this separates the two capture streams, not individual people.
  oto does not identify or label individual speakers within the meeting side.
- Microsoft Teams recordings can be imported and transcribed on-device.
- Transcripts are searchable in history and exportable as plain text, Markdown, or JSON.
- Everything runs locally; nothing is uploaded.
- Guide: https://tryoto.app/meeting-transcription-mac.html

## Accuracy and Screen Context (v2.2.0)
- Major transcription accuracy upgrade across engines.
- Optional Parakeet V2 English model for English-only work.
- Screen Context (opt-in, off by default): reads a single frame of the screen to pick up
  name and term spellings, then discards it. Nothing is stored and nothing is sent.

## Language Support

- Major languages: English, Spanish, Chinese, Japanese, Korean, German, French, Portuguese, Russian, Italian, Polish, Arabic, Hindi, Dutch, Turkish, Vietnamese, Thai, Indonesian, Greek, Czech, Romanian, Hungarian, Swedish, Danish, Finnish, Norwegian

FREQUENTLY ASKED QUESTIONS
================================================================================

Q: Does oto work without internet?
A: Yes. Transcription runs on-device, so no internet is required to transcribe. (The
   optional cloud AI cleanup feature, off by default, is the only thing that would use the network.)

Q: Which transcription engines does oto use?
A: Three local engines (Whisper, Parakeet v3, and Apple SpeechAnalyzer), all running on your Mac.

Q: Does it translate or just transcribe?
A: Both. Transcribe in your language, or use Whisper to translate supported speech to English.

Q: What Macs are supported?
A: Macs running macOS 14.0 or later. Optimized for Apple Silicon; Intel Macs also supported.

Q: Is it really $8 forever?
A: Yes. One payment on the Mac App Store unlocks every feature, including all future updates. No subscription, no upsell, no "pro tier" later.

Q: Can I share with family?
A: Yes, Family Sharing is included at no extra cost.

Q: How is my privacy protected?
A: Transcription is on-device and audio never leaves your Mac. No account, no app telemetry. Optional cloud AI cleanup is off by default and only ever sends transcript text, never audio.

Q: Does oto have a command-line tool?
A: Yes. Install the `oto` command from Settings → Advanced. From the terminal you can
   transcribe files (`oto transcribe < file.m4a`), start and stop recordings, and browse
   your history. Results also land in the app's history.

Q: Can AI assistants like Claude use oto?
A: Yes. oto includes an MCP server. Settings → Advanced gives you a ready-to-paste config
   for Claude Desktop, Claude Code, Cursor, or any MCP client. Connected assistants
   transcribe audio through oto fully on-device: no cloud transcription API, and audio
   never leaves your Mac.

Q: Can oto transcribe meetings?
A: Yes. Long-form meeting recording captures your mic and the meeting audio as two
   echo-cancelled streams and returns a two-sided transcript, your side and the meeting
   side kept apart. It does not tell individual speakers apart within the meeting side.
   Teams recordings can be imported, and everything runs on your Mac.

Q: Is oto on iOS?
A: An iOS version is coming soon and will be free on the App Store. Today oto is available as a Mac app.
