SoundProof: AI Hi-Fi ID

Frame the rack. Snap. Identify.

SoundProof is the AI-powered vintage hi-fi identification companion for collectors, working restorers, and anyone who has ever inherited a tube amplifier or pulled a dusty receiver out of a closet and wondered "what is this?"

Point your camera at any vintage receiver, integrated amplifier, separates rig (preamp + power amp), turntable, tape deck, tuner, or speaker. SoundProof uses Claude Vision to identify the make, model, year built, era, finish, topology (tube / solid-state / hybrid / class A / class AB), tube complement, power output (W/ch RMS), frequency response, S/N ratio, THD, country of origin, original retail in USD, and an estimated market range. Plus the historical significance, notable owners, common failure modes, restoration considerations, and notable variants in the lineup.

Built for the audiophile audience -- not retrofitted from a generic image identifier.
