This project relies on OpenAI to generate a newsletter. Enter your favorite topics, add your own links, and let the app generates a digest for you. Behind the scenes, webpages are downloaded, and the content is summarized using the LLM. The app takes care of rendering the result in a single page.

This app is powered by Spring AI, an open-source Spring project which simplifies the use of AI technologies for your Java project.

Use Java 17+ to build and run this app.

Use this command to build the app:

./mvnw clean package

The application was tested with 3 AI providers: OpenAI, Azure OpenAI and AWS Bedrock based on Llama2. Choose the one you preferred and enable it based on the options below.

You need an OpenAI API key to run this app. Refer to this page to get an API key.

Set your API key as an environment variable:
