Steps
1. Initial Prompt
I started by defining a prompt that described both the functionality and UI layout for the app within Famous.ai.
2. User Input Interface
I set up a text input field for lyrics (with a 200-word limit) and added dropdowns for genre and voice selection.
3. Integrating AI-generated Music and Text-to-Speech
Upon submission, the app uses Cassette AI to generate a background track in the chosen genre and Eleven Labs API to convert the inputted lyrics into vocals, matching the selected voice style.
4. Connecting Supabase as Backend Service
I connected the app to Supabase to handle backend operations. I selected a Supabase project as part of the setup.
5. Providing API keys for External Services
Famous.ai will ask user to input API keys for any external API service that is being used in the application in my case it happened to be Eleven Labs and Fal.ai
I can click on "How to get this" to view instructions for obtaining the API key. Once the keys are filled in, I can submit them to continue the application generation process
