Frequently Asked Questions

YouTube's default transcripts are a great starting point, but they often lack proper punctuation, capitalization, and can misinterpret words. Our service uses OpenAI's GPT-4o-mini to intelligently clean the raw text, correcting errors and formatting it into a polished, human-readable document. We also use the video's title and description for context, which significantly improves accuracy for specialized topics.

Our backend relies on two key technologies. We use Apify's `youtube-scraper` and `youtube-transcript-scraper` actors for robustly and reliably fetching video metadata and raw transcripts. For the cleaning and polishing phase, we use OpenAI's `gpt-4o-mini` model, which provides an excellent balance of speed, cost, and high-quality text generation.

Absolutely. We are a developer-first service. We provide a comprehensive REST API that allows you to integrate our transcription service directly into your applications and workflows. You can find detailed information, endpoints, and examples in our API Documentation, and you can test it live in our API Playground.

You can transcribe any public YouTube video that has auto-generated or manually uploaded captions available. Our service works with videos of any length, from short clips to multi-hour lectures, thanks to our intelligent chunking mechanism. The language of the transcript depends on the language available in the source YouTube video.
