Show HN: CPU-only transcription for YouTube, TikTok, X, Instagram videos
Summary
Show HN introduces yapsnap, a CPU-only transcription tool that converts video and audio from YouTube, TikTok, X, Instagram, or local files into plaintext without relying on GPUs or cloud services. The project emphasizes offline operation, small dependencies, and privacy, using a streaming transducer (Kroko English) with an ~80 MB model via sherpa-onnx, and leverages yt-dlp and ffmpeg for fetching and decoding. It targets developers and content creators who want fast, local transcription with optional timestamps.
