Pros	Completely free and open source, with no watermarks, sign-ups, or upload limits Runs locally on your GPU, so images never leave your computer Batch mode upscales entire folders in one pass Supports extra community-made models beyond the built-in ones, plus GPU selection Native apps for Windows, macOS, and Linux with a simple before/after workflow	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	Requires a Vulkan-compatible GPU; many integrated graphics chips and CPUs will not work Cannot deblur or fix out-of-focus images, only enhance low-resolution or pixelated ones AGPL-3.0 license can complicate embedding it in closed commercial products Large images and big batches can be slow or memory-hungry on modest GPUs	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
