Papyra gives you a calm, private home for notes that stays as easy as sticky notes while quietly linking everything together like a wiki. Cards pin, colour, and drag into place on your desk, and opening one drops you into an editor where slash commands insert headings, checklists, tables, or maps without leaving the keyboard. Type two brackets to link another note, and backlinks gather the other direction automatically, following the note even if you rename it. Notes save themselves, and every earlier version is kept, so you can scrub back through history and restore the draft you actually wanted. Sharing a note lets several people type in it together with visible cursors, comments in threads, and mentions that bring the right person in. Private notes lock behind a PIN or your fingerprint and sit encrypted on disk, while a daily journal page collects the day with a mood and a calendar to browse the year. Search covers notes, to-dos, and attachments with highlighted matches, and image text and audio transcripts can join the index. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GPL-3.0 licensed.
