In this video, I'll show you how to build a simple AI application using Cursor, v0 by Vercel, combined with a background removal model from fal.ai. We'll start by setting up the background removal model, referencing API documentation, and creating a new Next.js project. Along the way, I'll demonstrate how to integrate an image uploader and process images with the Fal hosted model. I'll also highlight the Composer view in Cursor, which helps streamline our coding process by referencing documentation and making file tweaks efficiently. By the end, you'll see how to add features like image downloading and full-screen view, making this a practical and easy-to-follow tutorial.

TS which our nextjs project currently does not have and then we see the correct way in terms of how to set up the file model so you can also reference this with the documentation if You' like then from here we have the tweaks to our front end it's going to have a diff and you can also go through this line by lines you can just command why each different section of the diff and accept it one by one or you can just accept the whole file and the other great thing with cursor is if you are a fan of just using your keyboard you can just tab through everything and they also have key bindings for basically everything that you want to do within the workflow so here we can just accept each of these different files or alternatively if you want to accept them all you can just command shift enter and you'll be able to have all of those changes applied you'll see all of those different check marks there here we'll exit of the composer then we're just going to have to get our API key from fou so I'm just going to go over to Keys We'll add a new key and we'll call it BG removal 2 and then within our project is we're just going to create A.L and then you can just paste in your key like that so fou key and then paste in the value so then you can save that out and close it out so once that's done what we're going to do is we're going to go over to our server so we do see that we do have to install the file dependency still we'll go back to cursor we'll open up a new terminal window and then I'm going to bun add and then we're going to install the foul AI client there now we just need a photo to test this so here I'll just save out this grade photo of this draft here we can select that photo so here we see that we see our selected image and if we click process image we see that it's processing we have that sort of pending state with it hopefully sending the request to file. and there we go now we have the background removed from our image now what we can do is we can go back to cursor and we can just start to give instructions on what we want to add to our application in this case I want to say I want to add the ability to download the image and make the image full screen what I did there is I command K to open it up again is probably going to be similar on Windows and then here you're going to see it go through and make some diffs to apply some updates that download image feature the toggle full screen in this case we're going to accept them all but you can also command y to accept them one by one we're going to accept them save up the file again then we're going to go back try this again we can just select our image process image then we see it's processing and then we'll see now we have a download image and a view full screen so view full screen we can click away download image it opens up the link to the image and then you can just tweak it so it didn't quite get what I wanted and I'm going to say I want the image to download not open in the browser and I want to add an X in the full screen view to close it out so this is just to give you a really quick example on how you can leverage cursor a VZ as well as foul to build out a really simple AI application so something like removing a background from an image you can do it a ton of different ways in my opinion there's no wrong way to do it there's definitely obviously different ways to do this sort of thing but here if I just process the image one more time and hopefully we see that we have those requests that we had asked for if I click view full screen we now see we can close it out we have that X there and if I click download image it actually downloads so that's pretty much it for this video if you found this video useful please like comment share and subscribe otherwise until the next one
