Questions & Answers

As answered by people managing MockFlow and visualOS.

What makes your product unique?

visualOS's answer:

visualOS stores your work as real files. Connect a folder and every board on the canvas becomes a folder on your disk, every document a Markdown file and every image an ordinary image file. There is no server and no account, so your boards work offline, sync through your own iCloud Drive or Dropbox, and stay readable even if you stop using visualOS.

Why should a person choose your product over its competitors?

visualOS's answer:

Choose visualOS if you work alone and want your boards to stay yours. Compared with Milanote, there is no 100-note limit and no subscription: the web app is free and complete, and the iPhone, iPad and Mac app is a one-time purchase. Compared with Miro or Apple Freeform, you get boards nested to any depth, stored as plain files, and the app works offline. If your team needs real-time collaboration, comments or share links, Milanote or Miro fit better.

How would you describe the primary audience of your product?

visualOS's answer:

People who think visually and work on their own: designers, photographers, illustrators and artists who build moodboards and project boards, plus students, writers and researchers who organise ideas on a canvas. Users often come from Milanote, Apple Freeform or Kosmik and want an offline tool without a subscription.

What's the story behind your product?

visualOS's answer:

We're Sarah Dorweiler and Gerald Reimertz, a husband-and-wife team from Nuremberg, Germany, who have been building things together for more than 20 years. As creatives we always organised our projects on visual canvas tools, but our files and ideas were tied to cloud services. We wanted the same visual overview for the files on our own devices: offline and private. That became visualOS, launched in 2026. We build it as a two-person team.

Which are the primary technologies used for building your product?

visualOS's answer:

The app is written in plain HTML, CSS and JavaScript, with no framework and no build step. The canvas is drawn with the Canvas 2D API and stays fast with thousands of elements. Data lives in IndexedDB or, through the File System Access API, in a folder the user chooses. The native iPhone, iPad and Mac app uses Capacitor plus Swift plugins built on UIKit, PencilKit (shape recognition) and Apple's Vision framework (handwriting search).
