Obius — Notes that evolve. Designed for the way you think. Your ideas don't arrive in straight lines. Obius is a visual workspace where notes carry color, ideas connect to each other, and what you wrote yesterday folds into what you're building today. Built for founders, PMs, designers, researchers — and anyone who outgrew Apple Notes but never quite fit into Notion. LOOPS — WRITE ONCE, REUSE EVERYWHERE Drop a Loop into any note — a named, reusable content block like @launch_checklist or @weekly_review. Edit it in one place, every copy updates instantly. Perfect for running lists, shared context, and anything you reference more than once. SECTIONS THAT CARRY MEANING Every section has an intent — a color that tells you at a glance what kind of thinking lives there. Open ideas, questions you're sitting with, work in motion, issues to fix, things that are done. Five colors. Five intents. Your thinking, visible. — Drag and drop to reorder — Collapse, expand, and nest sections — Rich content: text, checklists, code, quotes, images, audio — Tap once to change a section's intent ECHOES — REMINDERS THAT BRING THE NOTE BACK Attach a time-based reminder to any Loop. Unlike calendar pings, an Echo resurfaces the full note when the moment matters — with all its context intact, not a one-line nag. OBIUS INTELLIGENCE AI that lives inside the workspace, not in another tab. — Generate full pages from a single prompt — Edit, rewrite, and refine content in place — no copy-pasting between apps — Smart titles that actually describe the page — Semantic search that finds ideas, not just keywords — Research context: pull what you need, paste, and think from there INSIGHTS THAT SURFACE WHAT MATTERS Obius watches your pages for patterns so you don't have to. Cleanup suggestions, related notes you forgot about, lists hiding in your text, and safety flags for leaked credentials or secrets. VERSION HISTORY, BUILT IN Every note quietly snapshots itself. Browse the timeline, restore any earlier version, watch your thinking evolve over time. No save button. No lost work. SHARE LIVE OR FROZEN Generate a short public link to share a live note that updates as you edit — or freeze a snapshot in time. Readable URLs. View counts. Comments optional. CALENDAR See your work across time. Plan ahead, look back, stay oriented — without leaving Obius. LOCAL-FIRST. PRIVATE BY DEFAULT. — Pages stored on your device first — Works fully offline; syncs when you reconnect — End-to-end encrypted sync — No tracking. No selling data. Not now, not ever. — Optional local-only mode for maximum privacy YOUR MIND. YOUR ARCHITECTURE. Obius isn't another notes app. It's a workspace shaped like thinking — simple enough to start in seconds, deep enough to grow with how you actually work. Designed for the way you think.

YouNotes is a digital note-taking app designed for learning, work, and creative thinking. Everything you need is in one place—notes, PDF annotation, an infinite whiteboard, mind maps, text documents, and more. In addition to Apple's built-in drawing tools, YouNotes provides a complete set of creative tools including Lasso Selection, Text, Mind Map, Shapes, and a Laser Pointer, making handwriting, annotation, organization, and layout feel more natural and intuitive. With YouNotes, you can enjoy: • Infinite Canvas Combine mind maps, handwritten notes, images, stickers, and shapes on an unlimited canvas where your ideas can grow without boundaries. • Mind Maps Create expressive mind maps by freely mixing text, images, and handwriting, making your ideas more visual, flexible, and engaging. • Seamless Sync Across Devices Works on iPhone, iPad, and Mac with iCloud Sync, so your notes are always available wherever you are. • Multiple Interaction Modes Choose between Apple Pencil Mode, Finger Drawing Mode, and Reading Mode to match the way you like to work. • Teaching & Presentations Use the built-in Laser Pointer to highlight important content during classes, meetings, or presentations. • Dark Mode Enjoy a comfortable viewing experience at night while reducing eye strain and helping extend battery life. From a simple idea, to a single page of notes, to an entire knowledge system, YouNotes is designed to be your quiet, reliable creative companion—helping every thought become clearer and every note more meaningful. Looking Ahead Traditional note-taking is about recording information, organizing it yourself, and searching for answers on your own. As YouNotes continues to evolve, my vision is to transform it into an AI-powered notebook built for the future. More than just a place to write, YouNotes will integrate powerful AI capabilities that actively support your learning—from capturing ideas to understanding concepts, from asking questions to finding answers. Every note will become more valuable as AI helps organize knowledge, explain complex topics, and solve problems—like having a personal tutor by your side whenever you need one.
