Show HN: Remove Sora watermarks in 5 seconds – without quality loss

Thanks so much! Really appreciate the kind words. Great question about the technical approach. You're on the right track thinking about the headers and caching - but the actual "magic" is a bit different than re-encoding. We're using a managed pool of authenticated accounts to access the clean versions directly from Sora's servers, to ensure compliance with laws and regulations. You're absolutely right that details matter - we spent a lot of time optimizing the request flow, connection pooling, and error handling to make it feel instant and reliable. Appreciate you spreading the word! Would love to hear feedback as more people try it out. We're keeping it free for casual use (3 removals/day) so people can test it risk-free.

Whoa, this is super slick and props for actually getting it down to ~5s. Most of the “AI cleanup” watermark tools I’ve seen are painfully slow and lossy, so this definitely stands out.

Quick question though: when you say it “pulls the original from Sora’s servers,” are you basically re-requesting the same file the Pro plan uses, or doing some kind of auth-handshake on the backend before proxying it to the user? I’ve seen a lot of different ways people handle temp media URLs, and it’s always wild how small details like headers or caching make the difference between slow and instant.

Either way, cool build. I love when someone spots an annoying friction point and just ships something that works. Gonna tell my media friends about this.
