On-Device AI: Privacy First

What is On-Device AI?

On-device AI refers to running artificial intelligence models directly on your local hardware—your smartphone or computer. Instead of relying on remote cloud servers to process your food logs and photos, all computation happens locally on your device's Neural Processing Unit (NPU) or CPU.

How it Works

When you take a picture of your meal or log a food item, our proprietary AI model analyzes the data instantly right on your device. The request never leaves your hardware, meaning you get immediate results with zero latency.

The Privacy Advantage

We built Katori around the core principle that your dietary data is strictly yours. By using on-device AI, we ensure:

• Data Stays Local: Your photos, eating habits, and health metrics are never transmitted to a third-party server.
• Reduced Exposure: Eliminating internet transmission minimizes the risks of data interception or profiling.
• Offline Functionality: You can log your meals even when you don't have an internet connection.

Need More Power? Cloud AI Fallback

While our proprietary on-device model handles day-to-day tracking with absolute privacy, some complex meals might need heavier processing. If you want, you can opt-in to use our off-device, cloud-based AI. This cloud fallback is significantly more powerful for identifying complex, mixed Indian thalis—giving you the ultimate flexibility between maximum privacy and maximum power.
