How to create an AR object and see it with reference to coordinates without writing an application?

Question

augmented reality

How to create an AR object and see it with reference to coordinates or external markers without writing an application? Maybe there are ready-made applications where you can download what you need, or could it be a website?
The quality is not important, it can be a very simple object, an inscription, etc. It is important that it be exactly an object prepared in advance, in a certain place on the ground according to "natural" markers (a door, a bench in a park, etc.) or according to coordinates. What is the easiest way to see such an object on a smartphone for everyone "who wants"?
