Vainu website does not function as expected❗️

Is your Vainu missing some buttons or is the text overlapping? Something just doesn't seem quite right?

The problem might be in the browser you are using. Please use Vainu one of the following browsers:




Internet Explorer and Edge are not fully supported and usually don’t work quite as well with cloud-services like Vainu and therefore some functions don't work in these browsers as they should. Best use one of the 3 browsers mentioned above for a better experience 😊
