Have you ever opened an app to record something, only to give up because you got stuck on the title and category first? Sometimes, the format wears you out before you even get to write down the thought that really mattered. Don’t force yourself to organize. Your thoughts are enough, just as they are. monolog is an app where you can record things as casually as sending a message to yourself, while AI organizes the tags and timing for you. All you have to do is leave things there, just as they come to mind. ■ monolog keeps recording from feeling like homework 1. Frictionless Recording - Leave things as casually as chatting with a friend. There’s no need to come up with a title or choose a folder. Capture them in whatever form they come to you — text, photos, links, even voice. 2. AI handles the organizing. You find it again in 1 second. - AI understands the context of the records you leave behind almost without thinking, and adds tags automatically. Later, when you need something, just find it right away with tags and keywords. 3. Records that speak to you again - These are not notes you write once and forget. The unfinished thoughts you left two days ago, a week ago, casually speak up and ask, “Haven’t done it yet?” Experience the moment when the past version of you — the one who knows you best — wakes up the present you. 4. A fast and safe space of your own - Local-first sync: It saves the moment you tap. Keep recording without interruption, even in airplane mode or on the subway. Once you’re back online, everything syncs safely on its own. - Strong privacy: Data used for AI features is never used to train models. ■ monolog is for someone like me • someone who felt stuck from the very first line of a memo app • someone who has managed life through “messages to myself” • someone with plenty of records, but no easy way to find them again • someone who values a single thought more than complex features ■ Reach for monolog at moments like these • Hard-to-remember details — “What was our home Wi-Fi password again?” • Kindness worth remembering — a friend’s gift preferences, your parents’ clothing sizes • Turning anxiety into reassurance — when you took your medicine, the pillar number in the parking garage • Fleeting inspiration — an idea that flashes right before you fall asleep • For the master organizer — where you put that thing you tucked away somewhere deep ■ monolog is a slightly slow app monolog is not an instantly responsive AI chatbot, nor a busy assistant managing your schedule. There is only one value we insist on: “Memory.” “Toss in a thought you wanted to remember, and even years later, find it again in 1 second.” • Freedom from the burden of recording: You only need to focus on writing. monolog quietly takes care of the rest in the background. • A place to find, not a place to ask: Instead of asking a chatbot, it helps you face your own past thoughts again in 1 second. Rather than speaking ahead of you, it is a tool that helps you bring your memories back most clearly. • Coexistence that doesn’t rush you: It does not push you with alarms going off all the time. But if an unfinished record is beginning to fade, it quietly calls back the past version of you at just the right moment. You may not feel a big change right away. But as your records build up, and the moment comes when you need your memory, monolog becomes the most reliable extension of it. Now, stop putting effort into recording. Start the experience of letting your fragmented thoughts return as meaningful stories, with monolog. Terms of Service : https://monolog.ing/terms Privacy Policy : https://monolog.ing/privacy

NonZero You don’t need perfect days. You just need non-zero ones. Life gets interrupted. Motivation fluctuates. Some days go quiet. What matters is not perfection - it’s return. NonZero is not a streak app. It’s a practice. NonZero helps you track the things that matter to you, set a minimum effort, and keep moving forward, even if that movement is small. --- What Makes It Different Minimum-Based Tracking Define your own minimum. One page. One rep. One minute. That counts. Non-Zero Day System A day doesn’t have to be perfect to matter. If you show up at least once, it’s non-zero. Resilience Index Resilience isn’t measured by flawless streaks. It’s reflected in how consistently you come back after missing days. The Resilience Index captures your pattern of returning — because refusing to stay down is what builds strength over time. Comeback Metrics See how often you resume, not just how long your streak lasts. Simple, Calm Design No pressure. No noise. Just a quiet space to keep moving. --- Built Around a Simple Principle Do not let a day become zero. And when you miss, return. NonZero is for anyone who believes progress is not about intensity, but continuity. As long as you keep coming back, you’re growing.
