Smart Food Logging

YuHeng provides an intelligent way to log your meals using Large Language Models (LLMs). It can transform unstructured text or photos into detailed nutritional entries.

Photo-Based Logging

The flagship feature of YuHeng:

• Instant Analysis: Take a photo of your meal and the AI will identify the dishes and estimate their weights.
• Asynchronous Processing: Uploading a photo triggers a background task. You can keep using the app while the AI analyzes your food. (See Recognition Queue for technical details).
• Visual Confirmation: Once analyzed, the results are displayed for your review before saving.

Smart Text Addition

You can also log food by typing a simple description:

• “Two eggs and a slice of toast”
• “Large bowl of beef ramen”

The AI parses these descriptions to find matching nutritional profiles.

Real-Time Adjustments

If the AI makes a mistake (e.g., misidentifying a protein or missing an item), you can:

• Edit Items: Manually change the amount or description.
• AI Refinement: Provide a text instruction like “The fish is actually salmon” or “Increase the rice amount”, and the AI will recalculate the entry based on your feedback.
