Pros	Runs entirely offline and locally, so audio never leaves your device Plain C/C++ with no runtime dependencies, making it easy to embed and ship in other apps Broad hardware support including CPU-only, Apple Silicon (Metal/Core ML), NVIDIA CUDA, Vulkan and AMD ROCm Quantization and multiple model sizes let you trade accuracy for speed and memory down to tiny devices MIT licensed with a large ecosystem of language bindings (Python, Go, Rust, Java, Swift and more)	Runs fully offline on your own machine, keeping audio private Permissive MIT license Handles files, YouTube links, and live microphone transcription Exports to TXT, SRT, and VTT, with speaker identification and a watch-folder option Hardware acceleration via CUDA, Apple Silicon, and Vulkan for faster processing
Cons	It is a developer library/CLI, not an end-user app, so you build or integrate it yourself The CLI expects 16 kHz WAV input, so you often need ffmpeg to convert audio first Features like speaker diarization and word-level timestamps are marked experimental Getting GPU/NPU acceleration working requires building from source with the right flags and toolchains	Accuracy and speed depend on the Whisper model size and your hardware; larger models need a capable GPU Whisper's translation feature outputs English, so it is not a general any-to-any translator Installers are unsigned, so Windows and macOS show security warnings on first run Intel Macs are no longer supported beyond an older release; current versions require Apple Silicon
