Knot turns your map into a journal. Every place you've been holds something. The friend you met there. The conversation that stuck with you. The ordinary afternoon you'd otherwise forget. Knot gives you somewhere to put it. Drop a pin, write down what happened, and your map slowly becomes a record of your life as you actually lived it. WHY A MAP Most journals organize memories by date. But that isn't how we remember. You walk past a coffee shop and the whole evening comes back. You see a street name and remember who lived there. Place is the thread that pulls memory loose. Knot is built around that idea. Instead of scrolling backward through entries, you look at where you've been and everything comes with it. WHAT YOU CAN DO Drop a pin anywhere and attach a memory to it Note the people you were with and how you know them Write as much or as little as you want, from a sentence to a full entry Watch your map fill in over time as a picture of where your life has actually happened Revisit any pin whenever you want to remember FOR PEOPLE, NOT JUST PLACES Knot started as a way to keep track of people. Where you met someone, what you talked about, what they mentioned they were working on. It's the kind of detail that matters and disappears fast. Pin it, and it's there the next time you're in touch. YOUR MEMORIES STAY YOURS Knot stores everything on your device. Your pins, your notes, and your people never leave your phone. There's no feed, no followers, and nothing to perform. This is a private record, kept for you. QUIET BY DESIGN No streaks. No notifications nagging you to log your day. No metrics telling you how you're doing at remembering your own life. Open Knot when you have something worth keeping, and close it when you're done. Start with one pin. See what your map looks like in a year.
