TranscriptHQ – One API for word-accurate transcription, translation, export

Summary: TranscriptHQ provides an API that extracts audio directly from videos, reduces background noise, detects speech, and generates word-accurate transcripts. It supports single videos, entire channels, and playlists, offers translation into over 100 languages, and exports in common subtitle formats.

What it does

TranscriptHQ fetches video metadata and audio, applies AI noise reduction, performs voice activity detection, and produces word-level transcripts at scale. It also includes a no-code web playground for translating and viewing videos with inline captions.

Who it's for

Developers needing reliable transcription APIs and non-developers who want to translate and watch videos with captions.

Why it matters

It solves the lack of accessible, accurate transcripts by bypassing native captions and scrapers, enabling transcription even when captions are unavailable.
