About the startup

Capslane is a REST API that extracts captions from public YouTube videos or generates timestamped transcripts when captions are missing. It returns results as plain text or structured segments with millisecond precision, and automatically falls back to AI transcription when native captions aren't available. The service is designed for developers integrating YouTube transcripts into applications, with production controls like API keys, usage limits, and request history.
