Brain 3 Line

The brain-3-line icon represents a stylized brain symbol, often associated with intelligence, cognition, and artificial intelligence. It is commonly used in contexts related to neuroscience, psychology, and machine learning.

In real-world applications, this icon appears in software and platforms focused on AI, such as TensorFlow, PyTorch, and cognitive architectures, where brain-inspired designs are used to represent intelligent systems.

From a UX perspective, the brain-3-line icon communicates the idea of intelligence, learning, and cognitive processing, and helps users understand the functionality of a feature or tool related to AI or machine learning.

Brain 3 Line is one of 3,135 icons in Remix Icon, made by Remix Design and released under Apache 2.0. It is drawn on a 24 × 24 grid.

Sign in (it's free), then open Get icon, Install with shadcn CLI, and pick your package manager to copy the command. It adds Brain3LineIcon to components/icons/ri-brain-3-line.tsx: one file, a size prop (24 by default) and every SVG prop, with no icon package.

Copy it as React (from Get icon, or the Code section): a typed Brain3LineIcon component you paste into your project, with no package to install. Only the icons you import reach your bundle. It works in Next.js and any React app.

Open Get icon, then Copy as code, and pick Vue, Svelte, Angular, Solid or Preact; the Code section shows each one too. Every version is one self-contained component with the SVG inside, and SVG and data URL copies are there for plain HTML and CSS.

With Pro, the shadcn.io MCP server lets Claude Code, Cursor or any MCP client find the Brain 3 Line icon, or any of 3,135 Remix Icon icons, and install it from a prompt.

It's drawn in currentColor, so it takes the text color wherever you use it: a class like text-primary recolors it. To bake a color in, set one in Customize before you copy.

Set width and height on the component, or a class like size-6. It's drawn on a 24 × 24 grid, so it stays sharp at any size. Customize also sets the size it exports at, its padding and rotation.

Yes. It follows the text color, so with text-foreground (or any theme token) it changes with your light and dark themes. The icon is a vector, so it needs no separate dark asset.

Next to a visible label it's decoration: add aria-hidden="true" so screen readers skip it. Standing alone, as in an icon button, give the button a name instead, like aria-label="Brain 3 Line", so screen readers say what it does.

Yes. Brain3LineIcon passes every SVG prop to the svg element, so <Brain3LineIcon aria-hidden="true" /> works, and so do role="img" with aria-label, or a title child, when it carries meaning on its own.

Yes. Open Get icon, then Download file: SVG for code or design tools like Figma; PNG, WebP or JPEG at 512px; or an ICO favicon with 16, 32 and 48px inside. Each one uses what you set in Customize.

Yes. Apache 2.0 allows commercial use; keep the license notice when you ship the icons' source files. The full terms are in the license, linked on this page.

No visible credit is required: Apache 2.0 only asks that you keep the license notice if you ship the icons' source files. Icons installed with the shadcn CLI already start with a comment naming Remix Icon, Remix Design and the license.

Yes. Copying and downloading it is free, and the shadcn CLI install only needs a free account.

Its tags are technology, AI, intelligence, psychology, cognitive and neural. Each tag page lists the icons that carry it from every library, which is the quickest way to find a match for Brain 3 Line in another set.

Remix Icon draws many icons in several styles: Fill and Line next to the default. Open the library and pick a style above the grid to see Brain 3 Line's siblings in it.
