The Mental Edge Alternative to Hume AI Expression Measurement
Hume AI retired its Expression Measurement API on June 14, 2026, pointing facial customers to a voice product. Mental Edge is the facial and micro-expression measurement alternative built for developers — with transparent, predictable pricing, deep micro-expression analysis, self-host options, and no vendor lock-in.
