15 days oldThe repository was created 15 days ago. New is not bad, but a brand new repository carrying a familiar-sounding name is the shape a typosquat arrives in, and there has been no time for anyone else to find a problem with it.

What its author says it does

Copied from the file, not written here

Transcribe audio or video files to text locally on macOS using parakeet-mlx (NVIDIA Parakeet via Apple MLX). Use when the user asks to transcribe an audio/video file, get a transcript, generate subtitles/captions (srt/vtt), or convert speech in a file to text. Triggers on "transcribe this", "make a transcript", "get subtitles for", or pointing at an .mp3/.wav/.m4a/.mp4/.mov file with intent to extract speech. Apple Silicon only.

Transcribe Audio

Local, offline transcription via parakeet-mlx. Requires Apple Silicon and ffmpeg. Resolve both commands with command -v before use and report a missing prerequisite instead of assuming an installation path.

Run

parakeet-mlx <file>                          # → <file>.srt (default)
parakeet-mlx <file> --output-format txt      # plain text
parakeet-mlx <file> --output-format all      # txt + srt + vtt + json
parakeet-mlx *.mp3 --output-dir ~/transcripts # batch

Default output format is srt. Pass --output-format txt when the user wants plain prose, not subtitles. Output lands in the current dir unless --output-dir is set.

Notes

First run ever downloads the model (~600MB) from Hugging Face, then it's cached. Expect a one-time pause.
Default model mlx-community/parakeet-tdt-0.6b-v3 is multilingual (~25 languages). Override with --model if needed.
Accepts audio and video (mp3/wav/m4a/mp4/mov/...); ffmpeg handles extraction.
For languages outside Parakeet's set, fall back to whisper-cli (brew install whisper-cpp), which covers ~99 languages.
