Juliet turns your smartphone into an autonomous digital coworker. Give it arbitrary goals, assign standing responsibilities, and let it operate your phone with native precision, sub-42ms inference, and verified safety boundaries.
External AI models provide replaceable language intelligence. The Juliet Runtime provides sensory perception, phone world state, action primitives, persistent memory, and strict authority boundaries. The external model can change from Groq to Gemini to DeepSeek — the Juliet Runtime remains.
Assign Juliet persistent roles. A shopkeeper installs Juliet on a shop phone to handle incoming customer inquiries on WhatsApp, match products from local catalog memory, and reply instantly. When discounts exceed ₹500, Juliet halts and escalates to the owner.
Traditional mobile agents freeze while taking 5-second screenshots. Juliet dispatches through a native hierarchy: Level 0 Direct Intents (<5ms), Level 1 Semantic Accessibility Nodes (<25ms), Level 2 Predictive Graph (<15ms), and Level 3 Groq LPUs (<42ms). 110x faster than cloud computer-use loops.
Financial applications (Google Pay, PhonePe, Paytm, net-banking) are hard-quarantined at the OS level. External customer messages are treated strictly as untrusted data, rendering prompt injections powerless. An instant hardware STOP button halts execution immediately.
Select any scenario below to observe how Juliet intercepts real OS events, evaluates authority rules, executes UI actions, and verifies screen state in sub-42ms.
