Solo

What is Solo?

Solo is an on-device voice transcription and AI rewriting app designed for macOS, iOS, and iPadOS. It captures raw speech, transcribes it, and rewrites the result into polished text, with processing performed on the user’s own Apple Silicon device.

The core purpose of Solo is to help people dictate and convert spoken words into usable text while avoiding cloud uploads and keeping the workflow available across multiple Apple surfaces.

Key Features

• 100% on-device transcription and rewriting: Solo processes your speech and produces rewritten text entirely on-device rather than sending audio to a server.
• No cloud / no network required: The app is described as working fully offline, including “behind any firewall,” and in airplane mode.
• Multilingual dictation with automatic detection: Solo supports dictation in 100 languages using automatic language detection.
• Powered by WhisperKit (on Apple Silicon): Solo is built to run on-device on Apple Silicon chips, including use of Apple Foundation Models referenced on the site.
• Private by architecture: The site states there are no server uploads, no latency from network calls, and no third-party trackers, analytics, telemetry, or SDKs.
• Writing style rewrites: Users can choose writing styles such as casual, professional, concise, or detailed to shape the rewrite.
• History & sync via iCloud: Transcriptions are saved and synced across Apple devices using iCloud.

How to Use Solo

1. Install Solo from the App Store on your Mac (macOS 26+) and/or iPhone/iPad (iOS/iPadOS 26+).
2. Start dictating using one of the supported entry points: the macOS menu bar app or the standalone iOS/iPadOS app (tap to record).
3. Review and copy the rewritten text (the site describes one-tap copy to the clipboard).
4. Paste into any app where text entry is supported—Solo includes support via system keyboard integration and insertion into text fields.
5. Use the writing style selector to rewrite your transcript in the tone you want.

Use Cases

• Email and message drafting: Dictate an initial draft, then rewrite it into a chosen style (e.g., professional or concise) and copy/paste into your email client or messaging app.
• Writing assistance for documents: Convert spoken notes into polished text and insert it into document editors or writing tools.
• Coding and technical notes: Use Solo in code editors or other text fields to capture ideas quickly and insert transcribed text without requiring an internet connection.
• Multilingual dictation for international work: Dictate in different languages (with automatic detection) and rewrite the output into the tone you need.
• Offline dictation workflows: Record and rewrite while traveling or in environments where internet access is restricted, since the app is described as working fully offline.

FAQ

• Does Solo send audio or text to a cloud service? The site states Solo does not use a server, does not upload, and that processing is performed on-device with no cloud involvement.

• Does Solo require an internet connection? Solo is described as working fully offline with no network required during use.

• How many languages does Solo support? The site states Solo supports dictation in 100 languages with automatic language detection.

• Where can I use Solo’s output? The site indicates Solo works in “any text field” such as emails, messages, documents, and code editors, and also describes system keyboard integration for direct text insertion.

• How does transcription history work across devices? Transcriptions are saved and synced across Apple devices via iCloud.

Alternatives

• Cloud-based speech-to-text and rewriting apps: These generally run transcription and rewriting on remote servers, which can involve uploads and online processing, unlike Solo’s described on-device workflow.
• Offline transcription apps without rewriting: Some tools focus only on dictation/transcription. They may not include the same AI rewriting step or writing-style controls described for Solo.
• Local speech transcription using OS features: Built-in system dictation and accessibility tools can capture speech, but Solo’s positioning emphasizes the combined transcription + AI rewrite with style options on-device.
• Text editing workflows using offline grammar/style tools: If you already have transcribed text, offline writing utilities can help refine tone and clarity—though they typically don’t provide voice capture and rewrite in one step.
