Neuroline: Think & Reflect

A private AI journal that lives on your iPhone

Neuroline: Think & Reflect is a private, on-device AI journal for iPhone. It is built for people who think a lot and lose too much of it: founders, writers, students, researchers and anyone whose best ideas show up at inconvenient moments. Neuroline gives those thoughts a calm, fast place to land, and then helps you find them again and understand them over time. Every part of it runs on the device. Nothing is uploaded, there is no cloud account, and your writing is never sent to a server.

Capture

Save ideas, reflections, plans and moments the instant they happen, by voice or by text. Capture is designed to be quick and quiet, so the app gets out of the way and the thought does not slip away while you are opening menus or choosing folders.

Recall

Find any thought without endless scrolling. On-device AI search works by meaning, not just exact keywords, so you can ask the way you actually remember something, such as that idea about pricing from last month, and Neuroline surfaces the entries that match what you meant.

Reflect

Neuroline notices patterns across your thinking over time: recurring themes, ideas you keep circling back to, and plans that are still unresolved. It then gently guides you deeper into them, turning a pile of notes into a clearer picture of what you care about and what you want to do next.

Private by design

Privacy is the product, not a footnote. Because the AI runs entirely on your iPhone, Neuroline never sends your thoughts anywhere: not to servers, not to the developer, not to anyone. If you have tried journaling inside a chatbot or a cloud notes app and felt uneasy about where your words end up, Neuroline is the alternative.
