Stop losing ideas in a pile of disconnected notes. NoteOrbit is a linked-notes app that turns everything you write into a living knowledge graph — every note becomes a node you can see, connect, and explore. Most note apps bury your thinking in folders. NoteOrbit does the opposite: type a note, drop a [[wiki-link]] to any other note, and the connection is built for you — both ways. Open any note and you instantly see what references it. Then step back and watch your ideas orbit as a glowing constellation you can pan, zoom, and tap to follow the thread. WHAT YOU GET - Write a note, add a [[wiki-link]], and NoteOrbit autocompletes titles and wires up the connection for you - Automatic backlinks so every note shows exactly what links to it — context folders can never give you - An interactive orbit graph that lays out your notes by how they actually connect - Instant tags with #hashtags to slice your notes any way you think - Hubs and orphans finder that surfaces your most-connected ideas and the notes hanging loose - Full-text search across every note, title, and link PERFECT FOR - Students and researchers building study and reference notes that reinforce each other - Writers and thinkers growing a personal knowledge base or second brain - Zettelkasten and PKM fans who want backlinks without a heavy desktop setup - Anyone journaling ideas and projects who wants to rediscover old connections WHY NOT JUST USE FOLDERS Folders force every note into one place and hide how your ideas relate. NoteOrbit lets a note live in as many contexts as it links to, then draws the map for you — so the connection you made months ago is one tap away, not lost three folders deep. PRIVACY Everything stays on your device. No account, no sign-in, no ads, no tracking. Your notes never leave your phone. FULL ACCESS NoteOrbit Premium unlocks the full experience: unlimited notes and connections, the complete interactive orbit graph, hubs, tags and the orphan finder, plus Markdown export to take your notes anywhere. Choose the plan that fits: - Weekly - Yearly - Lifetime (one-time purchase) Open NoteOrbit, write your first note, and link it — watch your thinking take shape.
