Stealward vs SideLinker

Stealward turns a MacBook or iPad into an AI anti-theft guard for the devices and belongings you leave behind. It uses the camera to understand what changes and alerts the iPhone you carry in real time. Arm protection before you step away in a café, library, coworking space, or airport lounge. AI Watchdog watches what you leave in view, while encrypted live video lets you check the scene from your iPhone. Stealward also detects movement, power disconnection, and loss of connection. HOW IT WORKS 1. Point the camera at the devices and belongings you want to protect, then start protection on your MacBook or iPad. 2. Let AI Watchdog watch the scene. It checks still frames during the live session, understands meaningful changes, and alerts your iPhone. 3. Check what is happening. Open the end-to-end encrypted live view from your iPhone, then review the recording when you need the full timeline. 4. Get essential security alerts. Movement, charger disconnection, low battery, or an offline device can trigger an immediate notification and a loud local alarm. LIVE VIDEO, RECORDINGS, AND AI Live encrypted video. See and hear what the protected device sees from your iPhone. Encrypted recordings. Session video and audio are encrypted on the protected device before upload, so only your own devices can decrypt them. AI Watchdog. With your permission, AI Watchdog checks still frames during a live session, watches the devices and belongings in view, and explains what changed in plain language. A clear event timeline. Review movement, connection, power, and AI events in one place. CORE ANTI-THEFT PROTECTION Movement alerts. Know when a supported Mac or an iPad is picked up or moved. Power alerts. Get notified when the charger is disconnected or the battery runs low. Offline alerts. If the protected device stops checking in, your iPhone lets you know within seconds. A loud local alarm. Draw attention to interference and help deter someone from taking the device. PRIVACY BY DESIGN Your recorded video and audio are end-to-end encrypted before upload. Only your devices hold the keys needed to decrypt them. During a live session, AI Watchdog analyzes still frames to spot potential threats. After analysis, those frames are encrypted at rest so only your devices can open them afterward. No email or password is required. Stealward creates an anonymous account protected by keys that remain on your devices. You can delete your account and its data from inside the app. GOOD TO KNOW Stealward is designed around two devices: the MacBook or iPad you leave behind and the iPhone you carry. There is no extra hardware to buy. Some featured capabilities require an in-app purchase, including AI Watchdog, live video, and recordings.
