Everyone’s talking about building apps with AI these days but when you actually try it you end up following confusing steps and still not getting the results you want that’s the real problem ai has made app development easier but only if you know the right tools and the right process. I’ll walk you through a simple step-by-step method to turn your idea into a fully working app; All right, to build an app from scratch using AI we are going to do four parts.
Setting Up Your Development Environment, AI App
The first part is to set up your app. In this part let’s set up everything to start building a mobile app and we are going to do this in just five simple steps. The first step is to create an account on Lovable. Now, Lovable is the AI platform that we are going to use to build our mobile application so to create an account just, click sign up now, click sign up with Google and as you can see we have successfully created the account.
Now you can just type in your app ID here like your chatting and Lovable will start building the app for you but if we enter a basic description like this it can cause errors and might affect the app’s features so instead of entering basic and descriptions we’re going to create a requirement document that includes all the details needed for our app design features and other technical functions.
Mastering the Blueprint: How to Create a Perfect App Requirement Document
Next let’s move on to the second step which is to prepare the app requirement document. Now to make things easier we have an AI tool that can help you create the app’s requirement document and to access the tool just, Now to prepare the app requirement document here enter a small description of your app; since I’m going to build an AI travel assistant app I’m entering the same here.
Once you enter that next enter your app’s name; i’m going to enter Trip Tuner. Since we are going to build a mobile application let’s choose mobile here,. On a side note you can also create a requirement document for a website using Gravity Write; so once you’re done click create content and as you can see Gravity has generated the app requirement document with the necessary features and other details.Now we have successfully created our app requirement document.
Phase-by-Phase Planning: Organizing Your App’s Structure
Now let’s move on to the third step which is to create a plan for your app. In this step we are going to create a phase-by-phase plan for our app to make the development process easier. Now this keeps things organized and helps the AI to understand how to build the app properly so to create the plan click here and as you can see our requirement document has been added here.
Now click create content and here you can see that Gravity Write has created the step-by-step implementation plan for our app; as you can see it has separated the plan into eight phases for my app. Now this will change based on the app that you’re building.
The Brain of Your App: Setting Up the Lovable Knowledge Base
Once you have created the plan let’s move on to the next step which is to add all the details to Lovable. Now adding the app requirement document and the development plan directly into the chat might confuse the AI and it can miss some important features so to avoid that we’re going to add the details to the knowledge base and by uploading it to the knowledge base Lovable will follow and execute all the details and build the app exactly as we planned.
So first let’s set up the knowledge base. To add that, paste it here then press enter and you can see that Lovable has created a blank project. Now to add the details to the knowledge base click here select project settings and click knowledge; so this is where we are going to add the requirement document to start building the app. Let’s go back to Gravity Write copy the app requirements and paste it here. Now follow the same steps for the development plan; copy the plan from Gravity Write and paste it here once you’re done click save,. Now we have successfully added the requirement document and the plan to Lovable.
Securing Your Project: Connecting GitHub and Supabase for Data & Storage
Next let’s move on to the final step of this part which is to connect Lovable to GitHub and Supabase. Before we start generating the app first we need to connect Lovable to GitHub and Supabase. GitHub is the place where you can store all your app files even if your Lovable account is deleted or you want to make changes later your files will be saved there and you can access it from GitHub anytime. And Supabase is the online storage database where your app’s data will be stored like the user details messages and other app details.
So first we’re going to connect Lovable to GitHub and to do that click on GitHub here and click enable GitHub sync; sign in with your GitHub account. If you don’t have one you can click here to create one; once you’re signed in click install and authorize and once you’re done click here select your account then click view on GitHub and it’ll take you to the GitHub repository where all your app files will be stored.
Now our project is successfully connected to GitHub and next let’s connect to Supabase. To do that let’s go back to Lovable click on Supabase here now click on connect Supabase here sign in with your GitHub account click authorize Supabase and here you can see that Lovable is asking permission from Supabase to access the app data. To enable the access we need to create an organization first; to do that just scroll down and click create organization and once again click create organization.
Now select create new project and here enter your project name password and the region to create a project; once you’ve entered all these details click create new project and the project will be created. Now let’s go back to Lovable and here you can see the project that we just created; click connect once again and as you can see Supabase is successfully created with Lovable.
Part 2: From Concept to Reality – Building Your App Phase by Phase
All right now we successfully set up everything to build the app so next let’s move on to the second part which is to start building your app. Now let’s build our app phase by phase following our plan so you can easily check out how it looks and how it works,. So to build the first phase let’s go to Gravity Write copy the first phase and paste it here now click enter and as you can see Lovable has started building the first phase and it is done.
In this phase the AI has built the welcome page which allows the users to choose their travel preferences to personalize recommendations. Now let’s check and see how it works; i’ll choose some travel preferences here and if you want to see the mobile view of the application click here. So this is how your application will look on the mobile and once you enter the travel preferences next the app will take us to the login page; i’ll enter the username and password to login.
Okay now that we’ve built the first phase in the same way let’s build the next phase of the application. Let’s copy phase 2 from Gravity Write and paste it in Lovable click here; as you can see Lovable has built further pages with relevant travel information and guides also users can find the travel destination by searching here,. Next now let’s follow the same steps to build the next phase; let’s copy the plan and paste it into Lovable.
Here you can see Lovable is asking us to approve the security policies to build this phase; if your application has got any security policies you can check those here. Now I’m good with the policies mentioned here so I’m going to click apply changes and as you can see we’ve got an error while building our app. If you face an error like this don’t worry just click here then click try to fix and Lovable will make the necessary changes and solve the error for you and as you can see the error has been fixed and we’ve successfully completed this phase.
Now let’s build the next phase; let’s go to Gravity Write now in this phase you can see that the plan includes the signup functionality so let’s build this. Copy the plan and paste it in Lovable; you can see that the user sign in has been added to the application,. Now let’s try to create an account so let’s fill in these details and click create an account; as you can see the account has been created. Now let’s see where the user account details are stored in the database;
so to check that let’s go to Supabase and you can see the account details are stored here. We have successfully built this phase and now we can move on to the next phase; i’m going to follow the same steps so just copy the plan from Gravity Write and paste it here. In this phase you can see our app includes the AI chat feature to assist users in real time so let’s try to chat with the AI; as you can see the chat features are not working.
Integrating Intelligence: Activating the AI Chat Feature with OpenAI API
To enable the chat feature we need to integrate an API key of a chat service provider. To do that I’m going to use the OpenAI API key which is a popular AI chat API provider used by ChatGPT; click here and it’ll take you to OpenAI. Click login now login with your Google account click create new secret key then enter app name here and click create secret key,. As you can see the API key has been created and once you got the API key copy it go back to Lovable here click add API key paste the key into the input field and click submit. Let’s check the chat feature again and you can see that the chat feature has been working well. Great so now we have successfully built the app.

If a user opens any of these destinations it’ll show the complete overview of hotels restaurants and the things to do in that place.
Also users can search for their favorite destinations here and get a complete trip plan by adding location trip date and budget and the completed trips will be shown here. The next feature in the app is the AI chatbot; i’ll enter this question to get personalized recommendations as you can see the AI has created top places with its explanation, pretty cool right?. All right here’s a profile page where users can change their name and avatar so this is an app that we’ve built using AI.
Now if you want to access the app easily on a mobile device we can create a shortcut to add it to your home screen so that we can access the app anytime from here instead of entering the URL in the browser. To do that open your web app in your mobile browser then click here now click add to home screen here enter the name then click add and here you can see we have added the shortcut on the mobile screen.
