Platform Advantages

Built for Performance & Privacy

Acoustic Feature Extraction

Client-Side Inference

Runs 100% locally using Web Audio API and native JS FFT. No audio streams are ever uploaded to cloud servers, keeping user data private.

Smart Neural AI

Temporal Delta-MFCCs

Captures spectral energy velocity across frames with Z-Score normalization. Accurately separates sharp transient impacts from background noise.

Sensifai Marketplace Metered Billing

Sensifai Marketplace API

Secured with Logto OIDC authentication and metered seamlessly via Gatekeeper REST API for pay-as-you-go credit and subscription tracking.
