Overview

Tofu is a private AI health companion designed for logging vitals and meals, with its core intelligence running locally on the device. This ensures that intimate health data never leaves the user's phone, addressing privacy concerns. The app was built based on field research that revealed the target users—often elderly—carried capable smartphones, debunking the assumption that they needed extremely low-end devices. The local parser achieves exact intent routing on a golden set, removing per-message inference costs. Tofu is free to use and aims to be simple enough for grandparents, emphasizing accessibility and ease of use without requiring an internet connection for its core functionality. The project is part of a broader effort by the developer to create products that balance user value and business viability, with a lifetime tier available.
