As answered by people managing Opal and Motion.
Opal's answer
All your content is on a visual, infinite canvas desk. Notes, documents, files, etc. are draggable icons that you can organize spatially because we remember WHERE things are, not just what they're called. Opal keeps your work in sight so your brain never drops it.
Opal's answer
When content is spatially organized, you stop losing content buried under folders, hierarchies, categories, and menus. Your brain begins to fire differently, sparking new ideas and spotting links, patterns, and opportunities it used to miss. - You connect ideas across clients, projects, and ideas - You Stay In Flow, No Context Lost, And No Rhythm Broken - You make faster, sharper decisions because every note and project is visible at once - You reuse your best work instead of rebuilding it from scratch - You eliminate the need for text-based searches and can find things even if you can't remember what you named them
Opal's answer
Solopreneurs, freelancers, people juggling multiple clients, visual thinkers, neurodivergent thinkers, and people who've quit productivity apps.
Opal's answer
Something was lost when everything went digital. Having used various tools for years, I eventually discovered a fatal flaw that nearly all knowledge management tools suffer from: their attepts to organize content became the means by which content got buried. Over time as more content gets added, it became harder to find things, especially when you can't remember what you called it.
We remember things in physical space because we see them all the time and register their existence subconsciously, even if we don't need them in the moment. For example, if you asked where my keys were, I could tell you instantly. This spatial reasoning and thinking effect is severely hindered in the digital space.
After enough frustration, I decided to do something about it: build a spatial knowledge management tool that lets you see everything all at once. As you pan and zoom around your workspace, you are registering the existence of things even when you don't need them in that moment. That changes everything over time. Organizing becomes less about categorization, labeling, or hierarchy, and more about placement and "where I left it". Your brain remembers where far more easily than what. This is why I built Opal.

Web-based application built on NodeJS, Express, Form.io (MongoDB), and JavaScript.

I use this AI productivity app called "Motion" (usemotion.com). It requires google maps or outlook. I really can't stand that but it's been so helpful for me, I still use google calendar as my main calendar. Source: over 3 years ago
