Memkeep

Memkeep is a shared diary for the people you love most. Some moments are too good to keep to yourself — and too personal to post on social media. Memkeep is a private, end-to-end encrypted memory book you build together with your partner, your closest friends, or your family. No followers. No ads. No algorithm. Just the two (or three, or four) of you. WHY MEMKEEP IS DIFFERENT • Truly private — every photo and word is end-to-end encrypted by default. Not a paid upsell. Not "encryption in transit." Real E2E. We can't read your memories. Nobody can but you and the people you invite. • Works offline, syncs later — built on a local-first architecture, so the app is fully usable on a plane, on a hike, or anywhere with no signal. Your entries sync automatically the moment you reconnect. • Built for two (or a few) — Memkeep is designed for couples and small friend groups. Create a shared space, invite your partner or your closest friends, and start writing. Family use is supported too. • No social media patterns — no likes, no follower counts, no public profiles, no algorithm deciding what you see. Just your shared timeline, in chronological order, the way memories actually happen. WHAT YOU CAN DO • Create a shared diary space and invite the people who matter • Write entries with text, photos, and dates • Comment and react on each other's memories • Browse a clean month-by-month timeline of your story • Keep a separate personal diary alongside your shared spaces • Use it on a flight, in the mountains, or anywhere offline PERFECT FOR • Couples — capture date nights, trips, anniversaries, and the small daily moments that make a relationship • Long-distance partners — stay close even when you're apart, with a private feed only you two can see • Close friend groups — document trips, inside jokes, and the years you spend together • Families — build a shared memory book across generations, without putting your kids on Instagram PRIVACY YOU CAN VERIFY Most "private" diary apps store your data in plain text on someone else's server. Memkeep doesn't. Your words and photos are encrypted on your device before they ever leave it. Even we, the developers, can't read them. Your shared diary belongs to you and the people you invited — nobody else. LOCAL-FIRST, BY DESIGN Memkeep is built on a modern local-first architecture (powered by Jazz CRDT). That means: instant writes, no spinners, no "trying to reconnect" errors, and a real app that keeps working when your signal doesn't. START TODAY Open Memkeep, create your first shared space in under a minute, and invite your favorite person. Build your story, one memory at a time. The little moments are the ones you'll want to remember in five years — Memkeep is where they go. Made with care for couples, friends, and families who believe their memories are theirs to keep. — — — Questions, feedback, or feature requests? We'd love to hear from you: hello@memkeep.app
