Best Offline Transcription Apps 2026: A Privacy-First Guide

Why Offline Transcription Matters

Most popular transcription services send your audio to cloud servers. While convenient, this raises concerns:

• Sensitive conversations become part of someone else's infrastructure
• Internet dependency limits where you can transcribe
• Subscription costs add up over time
• Privacy policies can change

Offline transcription apps process audio entirely on your device. Your recordings never leave your control.
