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.

Memol
Read full descriptionHide full description
Memol is a notes app built on one idea: it's okay to forget. Notes aren't for remembering. Write something down, let it leave your head, and just ask the AI when you need it back. Write as a team, and a colleague picks it up right when you've forgotten it. We built Memol so you can work with a clear head, always. 【Who it's for】 • People who take notes but can never find them later • People whose notes turn to chaos because tagging and foldering is a hassle • Companies and shops where only one person knows how something works • People frustrated by Evernote's price increases • People who find Notion too heavy and feature-packed • Students and their study notes 【What makes Memol different】 ■ AI search — no tags, no folders needed The AI understands every note by meaning. Search with vague, natural phrases like "the hiring plan we decided in last month's leadership meeting" or "that design idea I had at the cafe" and you'll find it. Notes you forgot to tag, notes from back when your folders were a mess — all findable. ■ Share with your team and end key-person risk Invite people to a workspace and everyone can AI-search any note, no matter who wrote it. No more work grinding to a halt when a veteran is out, or knowledge vanishing when someone leaves. Important notes can be locked to "view only," so you can share them without risking unwanted edits. ■ Great for students, too Lecture notes, exam prep, report drafts, reading notes. ■ Simple, pleasant writing A focused editor with the extras stripped away. Markdown, image attachments, tables, and code blocks are all there when you need them. You can also capture voice notes that transcribe as you speak, and let AI start a draft from just a topic. 【How people use it】 • Sharing meeting minutes across a team • Sharing customer records (salons, clinics, animal hospitals, and more) • Managing client-specific rules (accounting firms, professional services) • Sharing recipes and manuals across locations (restaurants) • Building up a library of repair cases (auto repair shops) • Property notes and customer history (real estate) • Lecture notes, exam prep, reading notes (students) If you take notes but never really use them, if your team struggles with key-person risk, if you're looking to move off Evernote, or if you're a student — if even one of these is you, give Memol a try.
