Questions & Answers

As answered by people managing LucidChart and Opal.

What makes your product unique?

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.

Why should a person choose your product over its competitors?

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

How would you describe the primary audience of your product?

Opal's answer:

Solopreneurs, freelancers, people juggling multiple clients, visual thinkers, neurodivergent thinkers, and people who've quit productivity apps.

What's the story behind your product?

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.

Which are the primary technologies used for building your product?

Opal's answer:

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