Steno vs Deepgram: Which Is Better for Voice Typing on Mac?

Deepgram has quickly become one of the most popular speech-to-text APIs for developers. Its Nova-2 model delivers fast, accurate transcription at competitive prices, and its developer experience is widely praised. If you are building a product that needs speech recognition, Deepgram is likely on your shortlist.

But Deepgram is an API, not a desktop application. If you are a Mac user who wants to type by speaking -- in emails, Slack, code editors, or documents -- you need a tool that works at the desktop level. That is what Steno does. It is a native macOS app that sits in your menu bar and inserts dictated text at your cursor in any application, system-wide.

This comparison explains both tools honestly. Deepgram is an excellent product in its category, and Steno is an excellent product in a different one. The question is which category you need.

Overview

Deepgram offers a speech-to-text API built on its proprietary Nova-2 model. It supports real-time streaming and pre-recorded batch transcription, with features like speaker diarization, language detection, custom vocabulary, and smart formatting. Deepgram is known for its developer-friendly SDKs, competitive per-minute pricing, and fast inference speeds. It is used by companies building voice assistants, call center tools, meeting platforms, and transcription services.

Steno is a native macOS menu bar app for personal voice typing. It uses OpenAI's Whisper model via Groq for sub-second transcription with high accuracy. The hold-to-speak interaction model makes dictation feel instant -- hold a hotkey, speak naturally, release, and your text appears at the cursor. Steno also includes voice commands, text snippets, smart rewrite, and a complete dictation history with WPM tracking.

Pros and Cons

Pricing Comparison

Deepgram offers pay-per-use pricing starting at $0.0043 per minute for the Nova-2 model. There is a free tier with $200 in credits for new accounts. The pricing is competitive for API use, but costs scale with volume. Deepgram also offers a growth plan and enterprise pricing for higher volumes.

Steno costs $4.99 per month or $34.99 per year for unlimited personal voice typing. There is a free tier with daily limits. For an individual who dictates daily, the flat-rate model is far simpler and more predictable than per-minute API billing. You do not need to think about usage metering or API keys -- just speak and type.

Who Should Choose Deepgram

Deepgram is the right choice if you are a developer or engineering team building a product that needs speech-to-text capabilities. If you are creating a voice assistant, a podcast transcription service, a call analytics platform, or any application that processes audio programmatically, Deepgram's API, SDKs, and competitive pricing make it an excellent foundation. Its Nova-2 model balances speed, accuracy, and cost in a way that is hard to beat for high-volume API use.

Who Should Choose Steno

Steno is built for individual Mac users who want to replace typing with speaking. If you are a writer, developer, support agent, or professional who needs fast, accurate voice input across every application on your Mac, Steno is purpose-built for your workflow. The text snippets, voice commands, smart rewrite, and dictation history create a complete productivity system, not just a transcription endpoint.

If you suffer from RSI or repetitive strain, Steno lets you rest your hands while maintaining full productivity across your entire Mac. No API keys, no code, no configuration -- just hold a hotkey and speak.

Frequently Asked Questions

Is Steno a competitor to Deepgram?

Not directly. Deepgram is a developer-focused speech-to-text API for building products. Steno is a consumer macOS app for personal voice typing. They serve different audiences and solve different problems.

Can I use Deepgram for voice typing on my Mac?

Deepgram is an API, not a desktop application. You would need to build a custom app on top of it. Steno is a ready-to-use macOS app -- download it, set a hotkey, and start dictating into any text field in under 30 seconds.

How does Deepgram Nova-2 compare to Whisper accuracy?

Both deliver very high accuracy. Deepgram's Nova-2 emphasizes speed and competitive pricing for high-volume API use. Steno uses Whisper large-v3 via Groq. For end-user voice typing, both produce excellent results with negligible differences in practice.

Is Deepgram or Steno cheaper for personal use?

Steno costs $4.99/month or $34.99/year for unlimited voice typing. Deepgram charges per audio minute processed via API. For personal voice typing, Steno is far more affordable and requires no development work.
