End your day feeling done — not buried. 88% of people go to bed feeling unaccomplished. Not because they didn't work hard, but because their tools fight them: a to-do list in one app, a calendar in another, a Kanban board in a third, and an AI chat in a fourth. Nothing talks to anything. Kaizen brings it all into one app that you actually want to open. → TIME-BLOCK YOUR DAY, NOT JUST LIST IT Drag tasks straight onto your calendar. See your real day — to-dos AND time blocks — side by side on a split screen (iPad/large screens). No more "I have 17 to-dos and 6 hours, what now?" — Kaizen shows you when, not just what. → AI THAT ACTUALLY KNOWS YOU You can use Kaizen's build in AI assistant or work with frontier models through MCP. Set persistent instructions ("Be blunt", "Push me on my side project", "Cut me slack on Fridays") and the AI shapes itself around you instead of you adapting to it. Brain-dump out loud, get a structured plan back. → KANBAN WHEN A LIST ISN'T ENOUGH Every project gets a board view. Drag tasks through Backlog → Doing → Done. Perfect for side projects, course work, and creative work where a flat list doesn't fit. → LIFE TIERLIST: SEE WHAT ACTUALLY MATTERS Hidden behind a long-press on the calendar icon: rank the areas of your life — Career, Health, Family, Learning, Side Project, ... — into a visual hierarchy. When you don't know what to work on, your tierlist answers for you. No other planner does this. → MAKE IT YOURS — REALLY YOURS Backgrounds per page. Custom fonts, sizes, icons. Opacity and blur per element. Custom colors. Windowed mode on larger devices. Most planners give you "dark mode and three theme colors." Kaizen gives you a workspace that feels like it was built for your brain. WHO IT'S FOR • Employees juggling work, life and a side project • Founders and freelancers who can't afford a messy day • Students whose calendar and homework live in different worlds • Anyone who's tried five planners and bounced off all of them WHAT YOU GET WITH UNLIMITED - Unlimited tasks, folders, and task lists - Calendar with day, week, month views - Drag-and-drop time blocking - Kanban board per project - Habit-style recurring tasks and reminders - iOS, Android, and Web — synced - Life Tierlist - Deep customization (backgrounds, opacity, blur, custom fonts) - Import/export your data anytime AI UNLOCKS - Kaizen AI with persistent instructions + MCP for Claude/ChatGPT - Speech task creation WHY "KAIZEN" Kaizen (改善) is the Japanese practice of getting 1% better, every day. Not a productivity hack. A way of building a life that compounds. START TODAY Spend 60 seconds importing your existing tasks. Block tomorrow morning. Notice the difference by Friday. Have an idea? Tap "Suggest a feature" in settings — we read every one.

Levin — For people with too much on their mind You're not unorganized. You just have too many things that matter. Your brain is not a to-do list. Most apps expect you to structure everything upfront. That's not how real life works. You think in fragments — half a plan in the shower, a deadline while cooking, a idea you'll forget by tomorrow. Levin catches all of it. Voice, text, image — whatever form it takes. You don't file it, tag it, or decide what it is. You just send it. Levin listens, pulls out tasks and deadlines, and keeps the rest as thoughts you can revisit later. It learns how you think. Over time, Levin understands your priorities, your patterns, what you care about. Suggestions get sharper. Your morning view shows only what matters now — not everything, just what's ready. What Levin does for you: Captures thoughts instantly in any format — no structure required Extracts tasks, deadlines, and priorities from what you say Organizes everything into topics automatically Gives you a calm morning focus view of what actually needs attention Connects related thoughts so nothing exists in isolation Gets smarter the more you use it — your context, your world Extracts payment details from bills and invoices — IBAN, amount, reference — ready to copy This is not another productivity app that makes you feel behind. There are no streaks, no inbox zero, no guilt. Just a place where your thinking accumulates into something useful — and progress happens without forcing it. You don't need more discipline. You need a system that works the way you think. Terms of Use: https://getlevin.com/terms
