Hush

Hush is an AI-powered sleep assistant designed to transform a spare phone or tablet into a smart baby monitor and sleep soother. Created by a clinical psychologist and software engineer in California, it addresses concerns about privacy and the high cost of traditional baby monitors by processing all audio locally on the device, ensuring that no recordings are stored or transmitted to external servers. The tool is aimed at parents seeking a secure, affordable, and effective way to monitor and soothe their infants.

Key features of Hush include on-device AI cry detection that recognizes a baby's cries in real time, with adjustable sensitivity for different environments. When crying is detected, the Smart Nanny™ feature automatically plays calming sounds to soothe the baby before they fully wake, and instant parent alerts are sent to a paired device. The system operates entirely offline for monitoring and soothing, with the exception of sending alerts, which requires an internet connection. Audio is processed in one-second snippets, analyzed for crying, and then immediately discarded, with only a "cry detected" flag sent to the parent device. No account is required to use the app, and there is no tracking or data collection.

Hush offers a curated library of science-backed sleep sounds optimized for infant calming, including white noise, pink noise, brown noise, rain sounds, womb sounds, heartbeat, shusher, fan, and hair dryer. Some sounds are available for free, while others are part of the premium tier. Users can also mix multiple sounds together and use ready-made presets tailored for specific needs such as colic relief or deep sleep.

The app is compatible with both iOS and Android devices and allows pairing across platforms, enabling parents to use any combination of devices. One premium subscription covers up to three devices, and users can share access with a partner by signing in with the same Apple or Google account. 99, all of which unlock additional features and sounds. No dedicated hardware is required, making Hush a flexible and privacy-focused alternative to traditional baby monitors.
