Ori is a journaling application that functions as a personal writing companion. Instead of presenting the user with a blank page, it listens to spoken or typed input about the user's day and composes a personalized letter back each evening. The app is designed to offer a space where the user's words, along with optional biometric data from a wearable device (such as sleep and energy levels), are combined to form a gentle reflection of the day. Ori does not provide advice, clinical diagnoses, or scores; it simply mirrors back what the user has shared. The primary workflow involves a brief daily check in. The user talks or types a few lines about whatever is on their mind, and the app listens, noticing details the user might overlook. After the evening settles, Ori writes back with a letter based solely on the user's shared content and any connected data. Over time, the app surfaces patterns in the user's days, drawn from real life rather than invented insights, allowing the user to see their own trends. The app is not a medical tool and makes no clinical claims. Key features include voice or text input, optional integration with wearables to read sleep and energy data (all numbers are displayed transparently), and a completely private experience. No account is required, and no user data is sold or shared. The journal lives entirely on the user's device, not on a remote server. Users control what data Ori accesses and can disable any feature at any time. The app is free for everyone, with no cost or subscription, and aims to be accessible especially for those who have never maintained a journal or had a confidant to talk to.
