Nucleus Icons
Origin Story
Beyond Generic Symbols
In 2017, AI, blockchain, and spatial computing were emerging, but designers were stuck with generic symbols that couldn't capture these concepts. Marketing teams needed visuals for workflows, design researchers lacked icons for their methodologies, and professionals needed symbols that could explain complex new systems in simple, visual terms. That's when we built Nucleus Icons: carefully researched, stylized symbols designed in a consistent style. We launched with 125 icons. Today, Nucleus has grown to 1,000 icons across three styles - Binary, Duotone Dark, and Duotone Light. What makes Nucleus unique is precision. Every icon is research-driven, capturing complex ideas - from conversational AI to design thinking methodologies - and turning them into accurate graphical elements. Not approximate. Not generic. Built for designers, marketers, and brand managers who need to communicate complexity without losing clarity.

FAQ
Questions & Answers
What kind of files do I get?
Nucleus is built for Figma and Sketch and fully optimized for both. You'll also get files compatible with Adobe Illustrator and IconJar. All icons are ready to export as SVG, PNG, and EPS for immediate use.
Can I customize the icons?
Yes. The Figma and Sketch files give you full control: adjust colors, weights, and proportions however you need. Changes can be applied across all 1,000 icons instantly.
How can Nucleus Icons be used?
All icons are designed for digital media - interfaces, presentations, apps, and web platforms across all screen sizes. They're built specifically for Figma and Sketch, with each icon uniquely named for easy management. For faster browsing across all categories, we recommend Iconjar (the tag search is handy), but it's not required, the files work perfectly without it.
