QuickSay vs SuperWhisper: Which Voice-to-Text App Is Right for You?

Platform: the deciding factor

This comparison is straightforward for most people. QuickSay runs on Windows. SuperWhisper runs on macOS. If you use Windows, SuperWhisper is not an option. If you use a Mac, QuickSay is not an option. For the minority of users who work across both platforms, the other differences below may help you prioritize.

Price

Both apps use a one-time pricing model, which is refreshing in a market dominated by subscriptions. QuickSay costs $29. SuperWhisper costs $249.99 for the lifetime plan. The price difference is significant, though SuperWhisper's higher cost reflects its local processing capabilities and the compute resources required for on-device AI models.

Privacy and offline use

SuperWhisper wins on pure privacy. It processes everything locally on your Mac. No audio ever leaves your device. This is a genuine advantage for users who handle sensitive material or work in air-gapped environments.

QuickSay sends audio to Groq's cloud for transcription and cleanup. It captures zero screen data and runs zero telemetry, but the audio processing itself is cloud-based. This trade-off enables QuickSay's smaller install size and lower price point, but it does mean you need an internet connection.

Text cleanup

Both apps use large language models to clean up raw transcription. QuickSay routes text through LLaMA via Groq's cloud infrastructure. SuperWhisper runs LLMs locally on your Mac. Both approaches clean up filler words, fix grammar, and format output. SuperWhisper's local processing means it works without internet; QuickSay's cloud approach means it works on less powerful hardware.

Developer credibility

SuperWhisper has strong endorsements from well-known developers including Andrej Karpathy and Pieter Levels. It has built a solid reputation in the Mac developer community. QuickSay is newer but purpose-built for the Windows ecosystem, where developer-focused voice-to-text options are limited.

Who should choose QuickSay

• ✓ Windows users — SuperWhisper does not support Windows at all.
• ✓ Budget-conscious buyers — $29 vs $249.99 is a meaningful difference.
• ✓ Users with modest hardware — cloud processing means your local machine does not need to run large AI models.
• ✓ Users who want a minimal install — ~105 MB versus large local model downloads.

Who should choose SuperWhisper

• ✓ Mac users — SuperWhisper is built specifically for macOS.
• ✓ Users who need true offline capability — everything runs locally, no internet required.
• ✓ Users handling sensitive data — audio never leaves your device, which is the strongest privacy guarantee possible.
• ✓ Users who value developer community endorsement — SuperWhisper has notable backers in the Mac dev space.
