PenNib AI

Analyze fountain pen nib grind profiles with AI macro photography

Data & AnalyticsFreemium

PenNib AI examines macro photographs of fountain pen nibs to characterize tipping material shape, grind symmetry, and slit alignment, identifying deviations that cause writing issues such as hard starts, railroading, or scratchiness. The system provides specific adjustment recommendations for nibmeisters and helps collectors verify grind quality on custom nib work. A grind profile database allows comparison against reference profiles for popular nib types.
