Browlens is an AI brow app that helps you find your best eyebrow shape. Upload a photo to get automatic brow mapping with six draggable control points. Adjust thickness, length, angle, spacing, arch height, and overall position. Read a left-right balance report comparing arch-height and brow-length differences. Then choose a brow style — Natural, Arched, Straight, Soft Angled, Feathered, or Defined — and generate an AI preview on your face. Brow mapping and analysis are free with no sign-up required.
