Update: You guys almost smoked and melted my server 😂 (Sora Watermark Remover) - Fixed & Mobile Ready!
Holy cow. I posted my free Sora Watermark Remover (www.UnMark.Online) day before yesterday, and I didn't expect thousands of you to hit it at once. 😅
The server struggled a bit, but I spent last night optimizing the site, and add some new fix, so it should be fast enough.
Updates based on your feedback:
* Mobile Fixed: The UI was broken on iPhone, now it’s smooth.
* Speed: Cleaned up the backend so downloads should start faster.
* Stability: Moved to a better host to handle the Reddit hug of death.
Regarding the Cost - A few of you DMed me asking how to share the GPU costs (which are getting a little scary lol). I finally added a "Support the Dev" button on the site.
if you want to chip in for the GPU costs, it would help. but absolutely no pressure.
Ideally, I want to keep this tool 100% free forever. I hate subscriptions for a basic tool.
Link is still the same: https://unmark.online
Let me know if the mobile version works for you now!
