PLOPI vs Our Postbox

PLOPI is a private diary for two that can begin with one unexpected line, one invite, or one person you want to answer. Sometimes a few words stay with you before you know much about the person. Instead of disappearing in a fast chat, those words can become a slower diary you can read again later. Write about a scene from your way home. A small thought that reminded you of them. A thank-you you did not want to lose. The feeling of a day that a photo alone cannot hold. With PLOPI, a short note, a longer letter, a photo, or a sticker can become part of a diary that belongs to just the two of you. A DIARY FOR JUST THE TWO OF YOU Invite one person and start a diary together. Use it with a partner, someone you miss, a close friend, or someone far away, without needing to reply right away. SLOWER THAN CHAT, EASIER TO KEEP PLOPI is not built around instant replies. Write at your own pace, let the other person read at theirs, and keep the feelings you may want to revisit later. WRITE LIKE A LETTER Encouragement, everyday updates, gratitude, or a small love letter. PLOPI gives you a calm place to write what did not fit into a quick message. ADD PHOTOS AND STICKERS Make entries feel personal with photos and stickers. Even a short line can become a memory worth opening again.
