Your head is not a filing cabinet. Stop treating it like one. Antichaos is the brain-dump-first organiser: open the app, dump whatever is rattling around (typed or spoken, one thing or twenty) and watch it become clean, categorised cards. Tasks, reminders, dates. A brain dump goes in, a clear plan comes out. BRAIN DUMP Type or talk. The AI splits your stream of consciousness into individual items, sorts them into your categories, spots deadlines, and flags what's genuinely urgent. You confirm with a tap. TASKS Every task in one place, personal and professional kept separate so you can look at either on its own. Sort by priority, by what is due soonest, or by what you added last, or switch to Focus mode for the urgent and important only. SHARING Send one card to someone who can actually help. They see the title, the notes and the steps, and from then on edits travel both ways. What stays yours stays yours: your reminders, your waiting-on, and the private ratings you give a task. Nobody can connect to you without a code you gave them, and it expires. THOUGHT PARTNER Stuck on a decision? Talk it through. It asks the questions a good mate would, then turns the outcome into actionable cards. It won't write your essays or make your decisions for you. CALENDAR DUMP Paste a roster or rattle off your week. Shifts, appointments and kid pickups land on the right days. Built with shift workers in mind. You can also bring your iPhone calendars in, read only, and pick which events become Antichaos events. BRIEFING Your week written back to you in plain words: what you got done, what is still open. Made to be read, or sent to whoever asked how it is going. WORKS OFFLINE You can capture and edit with no connection. Your changes queue up and sync the moment you are back. ALSO IN THE BOX • Insights: what you actually finished, including recurring wins • Recurring tasks, reminders, categories you control • Light mode, dark mode, or follow your phone Free 28-day trial of AI features. Your data is yours: export your tasks and decisions as plain text, or delete your account and everything in it from Settings. Antichaos Core and Antichaos Premium are auto-renewable subscriptions, monthly or annual. Prices are shown in the app before you buy, and you can cancel any time in your Apple ID settings.

Verdict
The clearest difference is in-app purchases: OPark at none against Antichaos's 4. Antichaos's advantage is update cadence (every 4 days vs monthly) and device support (3 vs 1). On price, ads and iOS requirement there is nothing between them.
