Congrats to the launch, @aleksandr_heinlaid ! Not sure if I am doing something wrong, but after installed the extension, nothing showed up. Any guidance?
This makes so much sense, I’ve been in that exact spot on calls and it always feels clunky trying to mock something up on the fly. Curious, how fast is the flow from capture to editing? Feels like speed is everything here
@alagerrka Thanks, totally get that - we've felt the same pain during calls. The flow is built to be instant: just click the icon, and you're dragging elements within seconds. No setup, no menus. Speed was a top priority from the start.
Hey Product Hunt! Write it from my heart - without AI :)
I’m an IT analyst, and the idea for UI Builder came during one of those classic Zoom calls with a client while discussing design changes in a CRM system.
I realized how tricky it can be to quickly show what a new button or checkbox might look like - right there, in the browser. Sometimes I used screen drawing tools (not bad, but clunky), or I’d just sketch something later and send it for review after the call.
But being able to test and agree on a rough idea live, during the conversation - really speeds things up.
So I built this: ➤ Drag and drop UI elements onto any webpage or blank canvas ➤ Edit text in place, resize blocks, rearrange things ➤ Take screenshots or copy to clipboard ➤ Works locally, no data tracking, no login
I searched around and couldn’t really find a Chrome extension that does this - most are just drawing tools or annotation overlays.
Have you seen a tool like this before? Would love your thoughts or similar examples you’ve used.
Congrats to the launch, @aleksandr_heinlaid !

@aleksandr_heinlaid @fullstack_x thanks! let us know if you won't manage the problem
@aleksandr_heinlaid @lembit_hunt Thanks both! It worked after following the guidance. Nice job!
Easy to use and lightweight, congratulations. Is there an option to add another person to an existing sketch/project?

@eljo_prifti Thanks, really appreciate it!
At the moment, there's no option for real-time collaboration - it's a solo tool for now.
But that’s a great idea, and I ll definitely add it to the backlog for future updates!
Perfect for quick prototyping during client demos! 👀

@shenjun Exactly! That’s one of the main use cases we had in mind - live edits during client calls . Thanks!
