Browlens is an AI eyebrow shape analyzer and virtual try-on tool. Upload a photo to map your natural brow geometry with six movable control points, then adjust thickness, length, angle, spacing, height, and arch height. A balance report compares left and right brow arch height and length. Choose Natural, Arched, Straight, Soft Angled, Feathered, or Defined styles and generate an AI preview. Brow mapping, editing, and analysis are free with no sign-up required.
