Which tool allows you to draw freeform paths in Illustrator?

The Pencil Tool is specifically designed for drawing freeform paths in Adobe Illustrator. This tool enables users to create fluid and natural-looking lines by simply clicking and dragging the mouse to draw freehand. The paths created using the Pencil Tool can be adjusted and refined after they have been drawn, making it ideal for creating custom shapes and designs that require a more organic feel.

In contrast, the Brush Tool primarily applies textures and styles to paths rather than allowing for the drawing of paths themselves. It is often used to enhance existing shapes with various brush strokes rather than creating new paths from scratch. The Line Segment Tool is intended for creating straight lines with precise endpoints, while the Shape Tool is geared towards generating predefined geometric shapes like rectangles, circles, and polygons. Therefore, the Pencil Tool stands out as the most effective option for artists looking to draw unique, freeform paths in their illustrations.
