Collective AI The future of AI isn’t one voice — it’s a council of the world’s best minds working together. Collective AI lets you build your own personalized AI council by choosing from 8 leading models: • OpenAI’s GPT-4o • xAI’s Grok • Anthropic’s Claude 3.5 Sonnet • Google’s Gemini 1.5 Pro • DeepSeek-V2 • Mistral Small • Meta’s Llama 3 70B • Cohere Command R+ Ask any question, and your council goes to work: 1. Each selected model generates its own response in parallel. 2. They review and critique each other’s answers — highlighting strengths, spotting weaknesses, and uncovering blind spots. 3. A final synthesis combines the best insights into one clear, balanced, and superior answer. The result? Smarter, more accurate, and less biased responses than any single AI can provide.

Turn your own iPhone, iPad, or Mac into a private home security camera. Set an old device to watch a room and its screen dims to a discreet dark monitor view — one that always shows a clear recording indicator, so it is never hidden — while it detects motion, saves event clips, and streams live to your other devices. Wake it any time with a press-and-hold. PRIVATE BY DESIGN Unlike typical CCTV apps, SentryBlack has no company servers watching your home. Your video stays on YOUR devices and YOUR own private iCloud — never our cloud, and never a third-party cloud you did not choose. • Live view goes device-to-device and is end-to-end encrypted. • If your network blocks a direct connection, you can optionally add a relay server of your own — the video through it stays end-to-end encrypted and the relay cannot decrypt it. SentryBlack provides no relay server, and this setting is off unless you fill it in. • Cameras, motion alerts, and clips sync only through your private iCloud. • No account, no sign-up, no tracking. USE ANY DEVICE AS A CAMERA • The screen dims to a dark monitor view with an always-on "REC" indicator and timer — discreet and power-saving, but never blank. • On-device motion detection saves a clip and snapshot of every event. • Press and hold to wake the screen. MONITOR FROM ANYWHERE • On another device signed into the same iCloud, tap Monitor to see all your cameras. • Get instant push alerts with a snapshot the moment motion is detected. • Watch live video — fastest on the same Wi-Fi, and end-to-end encrypted everywhere. SENTRYBLACK PRO The free version records with motion detection, sends cross-device alerts, and streams live on your Wi-Fi (with a small banner ad on non-camera screens; iPhone and iPad only — the Mac app has no ads). SentryBlack Pro adds: • Cloud clip backup to your own iCloud • Unlimited event history • HD live view • Person detection & motion zones • Multiple cameras • No ads Pro is an auto-renewing subscription (monthly or yearly) with a 3-day free trial. One subscription works on iPhone, iPad, and Mac. Payment is charged to your Apple Account; it renews automatically unless cancelled at least 24 hours before the period ends. Manage or cancel anytime in Settings. Note: because Apple stops the camera when an app is in the background or the device is locked, a camera device must stay on and in the app while on duty — keeping it plugged in is recommended. Please use SentryBlack only to monitor your own property and spaces.
