Questions & Answers

As answered by people managing visualOS and PureRef.

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).

  • how do u guys organize your visual inspiration/refs digitally?
    I mainly use offline means: organising all my files in a hierarchy of folders and using pureref (which I highly recommend) to make moodboards, and ofc an external hard drive to save backups. The only online means I use is google drive... Source: about 4 years ago
  • HELP! So I want to trace this Image(704x702) into a Pixel art (32 x 32 or 40 x 40) but when I resize it, it gets like this (2nd picture) and if I don't, then the pixels are too small, What do i do?
    If you just want the image to be a transparent overlay while you draw 'through the image'(with it being unchanged) you can use something like Pureref(pureref.com) to set the image as always on top + turn opacity down a bit. Source: over 4 years ago
  • Hide user name in menu bar.
    If you can’t get it to work inside of max, I thought of a free easy workaround you could try. I use the software pureref to manage and quickly access reference images. You could just resize an empty pureref window to cover your username.... Source: over 4 years ago
