A search that takes natural language and returns results. A GPT-powered movie search is a great first AI feature: send the query, get movie names, look them up on a movie API, and display the results.
To keep the API key safe. Putting the key in client-side React code exposes it to anyone. Call a backend or serverless function that holds the key and calls the AI, so the key never reaches the browser.
