Hume AI

Hume AI belongs in the database because it solves a narrower but very real builder problem than most general AI platforms: emotionally aware voice and multimodal interaction. The checked product and pricing surfaces position Hume around text-to-speech, empathic voice interfaces, expression measurement, and multimodal analysis across audio, video, images, and text. That makes it a specialist platform for teams building voice products, conversational experiences, and affect-aware interfaces rather than a generic model API vendor.

It also deserves inclusion because the pricing is unusually transparent across both subscriptions and raw usage. The checked pricing page publicly shows Free at $0/month, Starter at $3/month, Creator at $7/month for the current promotion shown on the page, Pro at $70/month, Scale at $200/month, Business at $500/month, and Enterprise as custom. It also publishes included text-to-speech characters plus pay-as-you-go rates for multimodal expression measurement across video with audio, audio only, video only, images, and text. That level of public pricing clarity is exactly what a premium tools database should preserve.
