Show HN: CPU-only transcription for YouTube, TikTok, X, Instagram videos

Yapsnap is a CPU-based transcription tool that converts video URLs (YouTube, TikTok, X, Instagram) and audio files into plaintext transcripts without requiring GPU, cloud services, or API keys. The tool runs entirely offline after an initial ~80 MB model download, supports 10+ languages, and offers optional features like speaker diarization and sentence-level timestamps, all with minimal dependencies.
