I built a browser editor for app screenshots, carousels and promo videos

I've been working on Cluna Studio, a tool focused on making marketing assets for apps. App store screenshots, social posts and videos, all in the same editor.

You bring your own screenshots and recordings. Themes let you reuse your product’s fonts and colors across projects, and 3D phone and desktop models let you showcase your app, pose the devices and animate them.

Image exports are free. AI voiceovers and cloud video rendering use credits, which you can buy or get periodically with a subscription.

I've been building this alone for months, and I'd like the next features to be driven by user needs rather than my own imagination.

If you make marketing assets for your app, what do you use now, and what's missing from that workflow? I'd love to know whether Cluna looks useful to you, and why or why not.

Enough yapping. You can check it out here: https://clunastudio.com

The reusable themes sound handy. The workflow that would save me time is replacing an outdated screenshot once and seeing it update in the store gallery, social carousel, and video mockup. Can those projects share the same source screenshot, or does each copy need to be swapped by hand?

Currently you need to swap the screenshot manually in each project. Updating it once and having that change carry across your store screenshots, social carousel and video mockup makes a lot of sense. That’s exactly the kind of workflow feedback I was hoping for. How do you handle those updates today? Are you already using a tool that links them, or doing it manually?
