The phrase "app to transcribe audio" gets used for two very different needs that require very different tools. The first need is transcribing existing audio files: converting a recorded interview, meeting, podcast, or lecture into a text transcript. The second need is live transcription: speaking in real time and having your words appear as text in whatever application you are using. Understanding which type of transcription you need is the first step in finding the right app.
Apps for Transcribing Audio Files
If you have a recording that already exists — an audio file on your computer or phone — and you need to convert it to text, you need a file transcription service. These apps accept audio uploads and return transcripts, typically within seconds to a few minutes depending on file length.
What to Look for in a File Transcription App
Accuracy is the primary criterion for file transcription. Since the audio already exists and you are processing it at your convenience rather than in real time, you can tolerate a few seconds of processing time in exchange for higher accuracy. Key features include speaker diarization (identifying which speaker said what), timestamp alignment (knowing when each word was spoken), support for your audio format, and reasonable pricing for the amount of audio you process.
Several dedicated transcription services focus on this use case and do it well. They are typically subscription or pay-per-minute services that accept file uploads through a web interface or API.
Apps for Live Audio Transcription (Real-Time Dictation)
If you want to speak right now and have your words appear in your document, email, or notes app, you need a live dictation tool. These apps do not deal with audio files — they capture your microphone in real time, transcribe as you speak, and insert text into your active application.
This is a fundamentally different product category from file transcription, and it requires fundamentally different technology. The tradeoff is latency vs. accuracy: live transcription must produce results fast enough to feel real-time, which means the system cannot always use the full surrounding context that would improve accuracy in a batch setting. However, modern live transcription systems are accurate enough that the practical difference is minimal for most users.
Steno: Live Audio Transcription for Mac and iPhone
Steno is built for live dictation and is the leading dedicated voice-to-text app for Mac and iPhone. It lives in the menu bar on Mac and works as a keyboard extension on iPhone. The interaction is simple: hold a customizable hotkey, speak naturally, release. Your words appear at your cursor in any application — Mail, Messages, Notion, VS Code, Safari, Slack, or any other text input.
Beyond raw transcription, Steno includes a Smart Rewrite feature that applies intelligent post-processing to your dictated text before insertion. This removes filler words, corrects capitalization, and formats text appropriately for the context — so what goes into your document is polished prose rather than the literal raw output of speech recognition. It is the difference between "um so I wanted to ask about um the meeting time" and "I wanted to ask about the meeting time."
Comparing Key Features for Mac Users
System-Wide vs. App-Specific
Some apps only transcribe audio within their own interface or in specific applications. For live dictation on Mac, system-wide coverage is essential — you want dictation to work in Mail, Slack, Pages, Notes, a terminal, a browser, and everywhere else without switching tools. Steno works system-wide by operating at the macOS input level, so any app that accepts keyboard input works equally well.
Hotkey Interaction Model
The way you activate and stop dictation matters enormously for workflow integration. Toggle models (press once to start, press again to stop) create friction in workflows where you alternate between typing and dictating. Hold-to-speak (hold a key, speak, release) eliminates this friction. Steno uses hold-to-speak, which is why it integrates so naturally into mixed typing-and-dictation workflows.
iPhone Integration
Most Mac dictation tools stop at the desktop. Steno extends the same experience to iPhone through a custom keyboard extension. If you use both Mac and iPhone for work, having a unified dictation experience on both devices eliminates the need to learn separate tools. The iPhone keyboard uses the same hold-to-speak model as the Mac app, so the muscle memory transfers directly.
For Transcribing Recorded Meetings and Calls
A common use case that straddles both categories is capturing meeting notes. Two approaches work well. The first is live transcription during the meeting: have Steno running and dictate key points and action items as they are discussed, adding them directly to your notes document without waiting for the meeting to end. The second is using a dedicated meeting recording tool that automatically transcribes calls and provides speaker-attributed transcripts afterward.
For your own voice notes and working dictation, Steno handles everything. For automatically transcribing multi-speaker meetings you are a participant in, a dedicated meeting transcription tool adds value that real-time single-speaker dictation does not provide.
Getting the Right App for Your Need
If your need is transcribing audio files that already exist — recordings, interviews, archived content — use a dedicated file transcription service designed for that purpose.
If your need is real-time dictation — speaking instead of typing, faster notes, less keyboard time — Steno is the right app. Download it at stenofast.com for Mac, or install the keyboard extension on iPhone from the App Store.
The best app to transcribe audio is the one designed for how the audio comes to exist — real-time speech needs a real-time tool, not a file upload workflow bolted onto a dictation interface.
