FAQ

Frequently Asked Questions

What is PunkFox Lab and its core software philosophy?
PunkFox Lab is an independent software studio founded in 2026, dedicated to crafting refined, high-performance applications for iOS and macOS. We build with a philosophy of radical focus, natural logic, and precise utility, creating minimalist tools that run efficiently and respect user workflows with zero bloat.
How do PunkFox Lab applications ensure absolute data privacy?
Our apps operate on a strict local-first architecture. Applications such as LiveSTT, VoxCap, and sketch.AR perform 100% of their core processing—including neural speech recognition and image rendering—directly on your device. We do not transmit your private audio, transcripts, or graphics to external cloud servers, guaranteeing complete data confidentiality.
Are your speech-to-text apps compatible with offline use?
Absolutely. LiveSTT is optimized for complete offline operation, utilizing local neural speech engines (Apple Speech Analyzer under iOS 26 and the optimized SenseVoice-Small model) to translate and transcribe audio instantly without requiring active internet connectivity.
Do macOS apps like Doodle Bloom and VoxCap support Apple Silicon?
Yes. All of our macOS applications are compiled natively to leverage the extreme performance of Apple Silicon (M1/M2/M3/M4/M5 series chips), utilizing on-device Neural Engines and GPU acceleration to run machine learning models, such as Stable Diffusion, with maximum speed and energy efficiency.

“Building software I actually want to use — for the web since 2002, iOS since 2010.”
