The Brush Tool in Adobe Illustrator allows users to draw brush-like strokes and paint with different options like fill color, brush size, and shape. It has various brush modes like Paint Normal to paint anywhere, Paint Fills to only paint fill colors, and Paint Behind to paint underneath existing artwork. Users can select the Brush Tool, choose a brush mode and properties, then drag on the stage to paint or use shift and drag to constrain strokes horizontally and vertically.
