VOID//TASK is the Productivity Operating System built for people who work fast, and refuse to settle for software that looks like it was designed in 2015. Every screen is crafted with a dark terminal-grade interface — monospaced type, neon accents, scanline overlays, and zero visual clutter. This is what task management looks like when it is engineered, not decorated. — COMMAND YOUR QUEUE — Create, prioritize, and manage tasks with military-grade precision. Four priority tiers (CRIT / HIGH / MED / LOW), eight project namespaces, and time estimates from 15 minutes to 48 hours. Drag to reorder. Search instantly. Archive when done. Speak your mind and the AI in the NEXUS view will create your project and tasks. — AI DAEMON — An on-device AI assistant lives inside the app. Talk to it. Tell it what you need to remember. The Daemon extracts task titles, priorities, estimates, and project tags from natural conversation — then injects them directly into your queue. No cloud. No latency. Private by design, powered by Apple Intelligence. — NEXUS KNOWLEDGE GRAPH — See your tasks the way your brain connects them. NEXUS maps relationships between tasks using AI-powered semantic analysis and deterministic pattern matching. Nodes cluster by priority, namespace, and meaning. Tap to explore. Pinch to zoom. This is your second brain, visualized. — FOCUS MODE — Lock in. Select a task, set your session length, and enter a distraction-free countdown. Inspired by deep work methodology and Pomodoro technique. Your calendar can auto-block the time slot so nothing interrupts your flow. — OCR SCAN — Point your camera at a whiteboard, notebook, or printed page. The Vision engine extracts text instantly and drops it into a new task. Handwriting to queue in seconds. — VOICE INJECT — Speak your task aloud. Real-time speech recognition transcribes it directly into the task input. Hands-free productivity when you are on the move. — STREAK TRACKER — A GitHub-style contribution heat map on your home screen. Every completed task lights up the grid. Watch your streak grow. Stay accountable to yourself. — CALENDAR SYNC — Connect your calendar and block focused time automatically. VOID//TASK finds the next open slot and creates an event matched to your task estimate. — DEPLOY DASHBOARD — Ship your progress. Review completed work, audit your throughput, and track what you have accomplished across every namespace. — MULTI MODAL NOTES — Record audio over images, notes, sketches, overlays. — TEAM COLLABORATION — Share, import and export with your team. Export to AI. MD file export. Integrations with other productivity systems. — BUILT DIFFERENT — No ads. No tracking. No analytics. No accounts required. Your data stays on your device. Period. VOID//TASK is built with SwiftUI, SwiftData, and Apple Intelligence — fully native, fully private, fully yours. Integrations for GitHub, Slack, Notion, Google Calendar, Jira, and more are on the way. Welcome to the VOID. Your productivity starts here. Jack in.
