Why Codfish
- Profile-driven captions. Define your house style once — reading speed, line length, gap timing — and every rule is validated live as you edit, so files leave your desk spec-clean.
- Export formats you own. SRT and VTT out of the box, plus a format engine for rolling your own. No more hand-massaging output to match a client template.
- Fully offline, fully private. Audio is transcribed on your machine with WhisperX. No uploads, no accounts, no telemetry — safe for NDAs, pre-release cuts, and locked-down networks.
- Easy-to-use editor. A streamlined interface with intuitive tools that make refining your captions feel effortless.
- GPU-accelerated (when available). NVIDIA CUDA support on Windows for fast transcription, with a CPU fallback for everything else — same app, same project files.
- Free and open source. Apache-2.0. Yours to use, fork, and audit.
