If you saw a memory warning from FloWords, you’re in the right place. This guide explains how FloWords uses your Mac’s resources and how to optimize for smooth performance.
During transcription, FloWords loads the AI model into your Mac’s RAM. Each model has different memory and accuracy characteristics.
Model Download Size RAM Usage Accuracy Whisper Turbo 547 MB ~2 GB ~93% Parakeet V3 640 MB ~2 GB ~94% Apple Speech No download Minimal ~92%
The app itself uses an additional 200-500 MB for processing and interface.
Transcription is CPU-intensive during processing:
Apple Silicon Macs process significantly faster than Intel
Processing happens in short bursts during recording
Larger models require more CPU time
Real-time factor varies by model and Mac
FloWords stores files in your Library folder:
