Demo is pretty much useless, all that happens when someone clicks on your example links is it shows a password prompt. You're going to have to give a much better teaser of your site if you want anyone to actually register for your site. I'm certainly not going to waste my time registering for a site where I have no idea what it does or how well it does it. There is a reason why sites spend time explaining their products to people. That time is important.
Hey, sorry about that. It was not intentional to put an authorization there. We have removed that. You can now click on example links and get the resulting UI.
I'm clicking on the annotate with a bounding box example. I'm running chrome. There is no way I can find to add a bounding box. There is a button labeled show instructions. It reports "Something wrong, we're on it! Try it later"
These aren't subtle bugs I'm reporting. Please try your own site yourself first before posting it to HN.
Point taken. To put a bounding box, you need to preselect a label first and then click on the image - that should work fine. If you still have patience with us, please check and let me know how it goes.
