Why Apple Silicon?

Yapper uses two on-device speech recognition engines — NVIDIA Parakeet and OpenAI Whisper — both optimized for Apple Silicon’s Neural Engine and GPU:

  • Fastest transcription — Parakeet achieves 110-190x real-time speed on Apple Silicon
  • Lower energy usage — The Neural Engine and GPU are optimized for ML workloads
  • Full model support — All models, including the largest, run smoothly

Storage Requirements

Yapper downloads speech recognition models on first use. The storage needed depends on which model you choose:

Parakeet models (NVIDIA):

Internet Connection

Yapper only needs internet for:

  2. Downloading speech models — One-time download when you first select a model
  3. AI features — Only if you use AI Transform or AI Q&A
  4. License activation — Brief connection to validate your license

Once the model is downloaded, live transcription works completely offline.

Checking Your Mac

To verify your Mac’s specifications:

  1. Click the Apple menu () in the top-left corner
  2. Select About This Mac
  3. Check the Chip (should say M1, M2, M3, etc.) and macOS version

If you’re running macOS 13 (Ventura) or earlier, you’ll need to upgrade to macOS 14 Sonoma or later before using Yapper.
