Grimzoo is your life's memory. You tell it what you lived through, and your AI clone gets to know you, memory after memory. CATCH IT WHILE IT'S THERE A thought, a moment, a fit of laughter: note it down in seconds from the Manor. Write it, speak it, add a photo or a fifteen-second clip. Even with no signal, your capture sends itself the moment the network is back — nothing is lost on the train. NEVER FACE A BLANK PAGE Three ways to write, depending on your mood. The Fireside: a guided conversation that draws the story out of you, then composes it back in your own words. Free writing. Or questions drawn from what you have already written. A question of the day is waiting every time you open the app. YOUR GRIMOIRE, SORTED ON ITS OWN Your Memories file themselves by life theme, by feeling, by year, by tag. Instant search finds a word; search by meaning finds the one you only half remember. And when it is the photo that shows it, the Memory surfaces anyway — the Grimoire then tells you the photo is why. THE ATLAS Your Memories land on a map. One pin per place, zoom all the way down to the town. The "Place" field even reads the town from your text, the way it already reads the date — and you can always correct it or clear it. THE WITNESS A memory is not yours alone. Ask someone close to you to fill it in: they answer from a plain link, with no account to create, and you choose whether to quote their words or fold them into your story. Nothing is written without you. TALK TO YOUR CLONE Ask it anything about your own life. It answers with your Memories, your voice, your way of telling a story — and tells you which ones it read. The more you write, the more it sounds like you. SHARE, IF YOU WANT TO Send a Memory with a plain link, or open part of your Grimoire to the people close to you — with your Clone, if they want to ask you things. Close it again whenever you like. YOUR MEMORIES ARE YOURS The content of every Memory is encrypted (AES-256) and hosted in Europe. Lock the app with Face ID. No trackers, no ads, nothing sold on. You can delete your account and everything in it from the app, in two taps. Grimzoo is free. Your Grimoire is waiting.
