What It Does

This workflow acts as a smart financial assistant that helps users stay on track with their savings goals. It fetches savings data from a Google Sheet, processes it to calculate key metrics like progress percentage, expected savings and remaining days and determines whether the user is ahead, on track or behind schedule.

Based on this evaluation, the workflow generates personalized financial nudges using an AI agent. These nudges include motivational messages, practical advice and updated daily savings targets tailored to the user's current progress.

Finally, the workflow formats this information into a structured email and sends it directly to the user, creating a fully automated feedback loop that encourages consistent saving behavior.
