@raphael0202 I added the idea to do on-device language recognition here

[teolemon]

What

Create a custom Tensorflow model for MLKit to classify Nutrition facts, Packaging instruction, Front and Ingredients photo on device Create a custom Tensorflow model for MLKit to classify food, pet food, cosmetics and other products on device

Explore using the on-device LLM for various tasks

• Food intake journaling
• Ingredient analysis
• FAQ/Support (chat?)
• other use-cases TBD
