This is a fantastic showcase of how Agentic workflows can seamlessly integrate into our daily lives to solve tedious tasks like comparing supplement labels. By combining Mastra's elegant Human-in-the-Loop capabilities with Gemini's powerful Multimodal vision and search grounding, the developer created a highly practical tool. It brilliantly highlights how accessible advanced AI has become for building genuinely useful weekend side projects.

"When you press 'Compare' in the Chrome Side Panel with multiple iHerb product pages open, the AI reads even the back labels and compares them in a table format. Furthermore, if you ask additional questions about the comparison results, Gemini's native search tool fires up and pulls up even the latest meta-analyses."
