What is Dottie?

Dottie is a private AI journal designed exclusively for iPhone that helps you reflect, make sense of your thoughts, and notice patterns over time. Every entry stays on your device — no accounts, no tracking, and no data sharing. You can write or dictate freely, and Dottie responds with gentle, thoughtful summaries and reflections that help you see yourself more clearly. When using Apple Intelligence as the LLM, personal data never leaves your device. Even when using cloud-based models like ChatGPT, Gemini, or Claude, your data is not stored or used for training.

Who it's for

• Anyone seeking privacy-first journaling – If you want a digital diary that never sends your thoughts to a server, Dottie keeps everything on-device by design.
• People who want AI-guided reflection – You’ll benefit from summaries and pattern recognition that help you understand your emotions and growth without overthinking.
• iPhone users who value calm, minimal tools – The app offers a distraction-free space that feels safe and human, ideal for daily check-ins or deeper writing sessions.

Key features

On-device privacy by default

All journal entries are stored locally on your iPhone. No accounts are required, and no tracking occurs. When you choose Apple Intelligence as your AI engine, your personal data never leaves the device.

Choose your AI personality

You can select from different AI engines and personalities — from a supportive friend to a thoughtful coach or a straight shooter. This lets you tailor the tone of reflections to what feels most helpful in the moment.

AI-generated summaries and reflections

Dottie highlights patterns, emotions, and growth over time. Instead of just recording entries, you get meaningful insights that help you see your own progress and recurring themes.

Flexible input methods

Type or dictate your thoughts anytime. The app supports VoiceOver, Voice Control, larger text, and a dark interface, making it accessible across different needs and preferences.

What stands out

All entries stay on your device. No accounts. No tracking.

This isn’t just a privacy promise — it’s the core architecture. Dottie doesn’t require you to trust a server with your most personal thoughts. Even when using cloud-based AI models, the developer ensures your data is never stored or used for training. Combined with the ability to choose your AI personality, this creates a journaling experience that feels both deeply personal and genuinely secure.
