Good fit for Engineers who want a scriptable, shell-friendly transcription pipeline with no daemon to operate.
Weak at No web UI, no live transcription out of the box; you build the meeting-recorder + speaker-attribution + summary glue.

Replaces these SaaS
- Otter.ai · Meeting transcription / AI notes
`git clone https://github.com/ggerganov/whisper.cpp && make`. Download a model (`bash ./models/download-ggml-model.sh large-v3`). Transcribe: `./main -m models/ggml-large-v3.bin -f meeting.wav -ojf` produces JSON with timestamps. For speaker diarization, pair with `pyannote-audio` (Python, separate install) or use `whisper-diarization` which bundles both. Summarize the resulting transcript by piping into Ollama / a local LLM.
