This system runs entirely on your local machine using the Firebase Emulator Suite, which simulates the Firebase cloud environment. It connects a local file system event to the Gemini API for analysis.

Core Components:

Local File Watcher: A simple script (e.g., using Node.js with the chokidar library) that monitors specific folders on your computer for new files.

Firebase Emulator Suite: Your local "cloud" containing:

Cloud Storage Emulator: To temporarily hold the file being processed.

Cloud Functions Emulator: To run the AI logic when a new file is added.

Firestore Emulator: To store the structured AI results.

Google AI (Gemini API): The brain of the operation. The local function calls out to this cloud-based API to perform the analysis.
