There is a companion blog post about it as well that gives an overview of how it works.

You can create a weekly workout plan to help you reach your goals. Information about you is stored in a local SQLite database. Report on your workouts to your assistant and they will log them for you. The assistant can access your stored information and historical workout logs to answer questions and help you on your personal fitness journey! 💪

Features:

• Context around how the AI is configured is hidden from the user.
• Data about the user is written in a structured format by the AI into a local SQLite database.
• Historical fitness log entries are stored and fetched from the local database.
• Provides a simple but powerful working example of how to create an AI agent in Elixir that integrates with your app.
