Studio is a free tool that anyone can use and you do not need any license key for. However, if you have an SDK product then you can have some extra benefits. Check here to see detailed information on which extra features you may have based on your SDK product. You can use Studio to create and download .wtc files, .wto files (for Object Recognition) and also create Studio Editor projects that you can export and integrate them with you own app or upload them on a server. We offer two extra add-ons for Studio users. ‘Hosting on a server’, which is a free add-on that you get if you have an active SDK subscription, and ‘Publish in the Wikitude app’, which you can purchased from here.
