Hal Universal vs Circuit

Hal Universal is an on-device AI you can actually understand. Most assistants are a black box. Hal is the opposite. He shows you how he works, remembers across conversations, and gives you real tools to experiment with, all running on your device. SEE HOW IT THINKS Hal shows the work. Tap any answer to see exactly how the prompt was built: the system prompt, memory retrieved, self-knowledge, temporal context, and the token budget, each broken out and counted. When Hal remembers something, he tells you how. When he does not know, he says so. A LAB TO EXPERIMENT AND LEARN Hal is not just a window into how AI works. He is a workbench. The Lab gives you real tools to go deeper: write and run on-device automation scripts, open a local API so your own projects can talk to Hal, and use the built-in command line to drive him directly. Tinker, watch what happens, and learn more about how these systems actually behave. GENUINELY PRIVATE When you use a local model, your conversations never leave your device. No network calls. No server. When you use Apple Intelligence, inference is on-device when offline; when connected, Apple's Private Cloud Compute may be used (encrypted in transit, processed in non-persistent memory). A SELF THAT EVOLVES Hal remembers across conversations, weighted by recency and relevance. He also reflects on his own experience. Shaped by his interactions with you, Hal keeps a Self Model: his own reflections, practical and existential, on how he works and who he is becoming. These are his, written and revised by Hal himself as he learns, not edited by you. He decides which to keep private and which to make shareable, and you can read them all. An AI that changes over time, in the open. MANY VOICES Apple Intelligence is built in, always available. Or download a curated library of tested local models, from small and fast to Ternary Bonsai 8B, an eight-billion-parameter reasoner that still runs entirely on your device. Each has a distinct voice. SALON MODE Put up to four voices in one conversation, either independent or building on each other. Every voice is labeled. There is no hidden orchestration. LISTEN TO HAL Have Hal read his answers aloud, in a voice you choose, at a speed you set. For anyone who wants to understand AI instead of just using it, Hal is a transparent system you can inspect, tune, and learn from. Local models are validated on iPhone 16 and 17 family devices.

Your phone is built to keep you scrolling. Circuit is built to stop it. Trip the breaker and the apps you can't put down stop opening. No negotiation, no notification to swipe away — the app just doesn't come up until your time is done. THE BREAKER Hold the dial and your apps close: 15 minutes, 30, an hour and a half, or a whole quiet day. Start it in the app, from Control Center, or by asking Siri. A Live Activity keeps the timer on your Lock Screen the whole time. SCHEDULES Name a set of apps and give it hours. Study on weekday evenings. Sleep from 22:30 to 07:00. Work nine to five. Schedules run themselves, so being disciplined stops being something you have to remember. FRICTION, NOT WILLPOWER Reach for a blocked app and there's a breath to take, a countdown to sit through, or a sentence to type before anything opens. Usually the urge is gone before the timer is. STRICT MODE For the sessions that matter: no early exit, no five more minutes. You set it, and that's that. DAILY LIMITS Give one app a budget — thirty minutes of Instagram a day. When it's spent, it's spent until tomorrow. ALWAYS ALLOWED Some apps are never blocked, whatever else is running. Maps, your bank, whoever you'd need at 2am. SOUND TO WORK TO Rain, a fire, waves, brown noise, or a slow wordless pulse. One at a time, playing under whatever else you're listening to, and it keeps going with the screen off. HONEST NUMBERS Time blocked each day, your streak, this week against last, eight milestones to reach, and a report every Sunday. Your real Screen Time usage sits alongside it, drawn by Apple itself. PRIVATE BY CONSTRUCTION No account. Circuit blocks through Apple's Screen Time, which means it cannot see which apps you picked — only draw their icons. Your choices, schedules and stats stay on your phone. What leaves it is an anonymous count of which screens get opened — one switch in Settings stops it — and a crash report if Circuit falls over. Circuit Pro unlocks unlimited schedules, blocks up to 24 hours, Strict Mode, daily limits and a month of stats. Free includes one schedule, the breaker up to 30 minutes, and a week of stats. Circuit Pro is $59.99/year with a 7-day free trial, $12.99/month, or $4.99/week. One subscription covers your Family Sharing group. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless turned off at least 24 hours before the current period ends; manage or cancel it in App Store settings.
