An iOS app that distils notes into usable knowledge with AI — application development for Apple iOS platforms

◷ Started 2022 as a web app · iOS rebuild since March 2026

Migrated from the artefacts of an earlier web-app project into the Apple world — with a clear new focus: synthesising notes with AI, securely, right on the smartphone.

— // FROM WEB APP TO iOS

This application was migrated from the web-app artefacts of an earlier project of mine into a native Swift foundation — Swift / Swift code / SwiftUI / SwiftData — with Xcode & the Apple Simulator in meticulous detail work.

The project had been on ice since 2022, because the client at the time dropped out and I saw no use for it until now.

— // AI-ASSISTED SYNTHESIS

In the meantime it turned out that the manual synthesis of notes can be considerably eased — and the quality of the results markedly improved — through the use of AI models.

On one hand, Apple Intelligence comes into play, keeping data security very high; on the other, integrating large frontier models makes it possible to handle an enormous workload — right on the smartphone.

— // STATUS & AMBITION

The app is currently in an early alpha phase and is expected to be completed in the autumn — after all, the entire development happens in my spare time.

The use of AI is deliberately kept to a minimum in this project: real, hands-on coding is excellent training and an indispensable foundation for working soundly with AI agents.

Keep smart Train yourself Know all your Code Understand the Project Delegate to your Agents

This guiding principle runs like a common thread through my work and areas of activity. Stay tuned — more on this exciting project here soon.
