YouTube videos,
as podcasts.

It's nearly instant. For most videos, our AI reads the transcript and generates your custom audio summary in just a few seconds. You can start listening almost immediately.

Absolutely. Sumcastr can process YouTube videos in multiple languages (including Chinese, Spanish, French, and more) as long as the video has a closed caption track available.

Currently, Sumcastr relies on YouTube's transcript data to generate highly accurate summaries. If a video has absolutely no captions (not even auto-generated ones), we won't be able to process it right now.

Right now, Sumcastr operates entirely within our clean, mobile-optimized web app. You can listen anywhere you have a browser, and we are actively exploring native podcast app integrations for the future!

Not at all. We use state-of-the-art AI narration models designed specifically for long-form listening. They sound incredibly natural, complete with human-like pacing and intonation.

The free tier is designed to let you experience the magic without putting in a credit card. You get up to 15 video summaries per month, 3 collections to organize your audio, and our standard high-quality AI voices.

It takes one click. We use Stripe for secure billing, and you can cancel or pause your subscription directly from your Sumcastr dashboard at any time. No emails to support required.
