Levin

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

Verdict
The clearest difference is ads: Underlairs at none against Levin's shown. Levin's advantage is update cadence (every 10 days vs every 3 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.
