Dottie is a private AI journal designed to help users reflect on their thoughts and experiences. It emphasizes privacy by storing all data directly on the user's device.

The key feature of Dottie is its use of Apple Intelligence as the LLM, which ensures that personal data never leaves the device. Additionally, it supports other AI models like ChatGPT, Gemini, and Claude, which run in the cloud but do not store data or use it for training.

The product works by leveraging on-device processing for maximum privacy when using Apple Intelligence. For cloud-based models, it maintains privacy by not retaining or training on user data.

Benefits include enhanced privacy and secure reflection, making it suitable for personal journaling without data exposure.

Dottie targets users seeking a private journaling tool, particularly those using iOS devices and interested in AI-assisted reflection.
