HackleAI

Calculate ideal hackle fiber density and wrap count for any dry fly pattern

Data & AnalyticsFree

HackleAI computes wrap count, fiber angle, and barb spacing recommendations for dry fly hackle based on hook size, target insect wing silhouette, and surface film float requirements. Its buoyancy simulation validates whether the recommended hackle configuration will support the body weight of the dressed fly at the target drift speed. Tyers can adjust stiffness class—soft hen to stiff rooster—and see updated float predictions in real time.
