A beautifully crafted, browser-based note-taking app with local AI, infinite canvas drawing, wiki-linking, developer-grade exports, and procedurally generated, collectible digital companions.
Every note, image, and checklist lives in your browser's IndexedDB. No databases, no cloud sync, no third-party servers. Your private ideas never leave your physical computer.
No sign-up, no email, no password, no tracking cookies. Open the file and start writing immediately. You are completely anonymous from the first keystroke.
Use it on a plane, in a coffee shop, or in a high-security environment. Zero internet dependencies — ever.
SuperNotes Online bridges the gap between a simple notepad and a complex knowledge manager — without the learning curve of either. Every feature is built right in.
A custom glassmorphic dropdown that formats your notes for X, LinkedIn, Slack, Discord, or Email with instant premium visual confirmation modals. Features a true standard Markdown compiler, optimistic zero-latency clipboard writes, and one-click auto-launch redirects!
Click once to open an infinite vector whiteboard directly inside your note. Sketch architecture diagrams, wireframes, and flowcharts alongside your writing — no context switching, no separate app.
Type [[ to instantly link any two notes. Hover over links to preview the target note's content in a floating popup without losing your cursor position. All backlinks are automatically tracked.
Built-in Pomodoro timer with play, pause, and custom durations for deep work. Auto-saves snapshots of every note body so you can browse the full history and restore any previous version instantly.
Paste images from clipboard, drag-resize with live pixel labels, embed YouTube cards that bypass local security policies, and upload local videos stored directly as Data URIs in your notes.
Meet your own procedurally generated developer companion! Every mascot is born with unique DNA, a rare 7-digit serial number, custom names, and gorgeous neon pixel aesthetics. Built as an interactive discovery engine, every roll offers a fresh surprise. Copy high-fidelity PNGs directly to your clipboard in one click and paste your companion instantly into X/Twitter to share your note-taking journey!
All essential formatting tools, checklists, syntax codeblocks, custom sizing, and real-time word counts. Now optimized with a universal tactile physics engine—every button click delivers responsive, physical, mechanical switch-style feedback!
No file clutter, no upload modals. Clicking 'Share' instantly renders your mascot with vibrant OKLCH colors, centers their circular pupils, lights up their glowing visor mouths, and copies them to your clipboard. Simply hit Ctrl+V on X/Twitter to share your note-taking partner with the world!
Unlock a conversational partner directly inside your notepad. Connects seamlessly with the official DeepSeek API to let you summarize complex files, ask deep questions about your second brain, write code, or brainstorm ideas in real-time — no context switching, just pure intelligent workflow.
SuperNotes Online gives you the best of both worlds: 100% private local intelligence and cutting-edge global reasoning.
📡 Local Connection Engine — Runs a private TF-IDF similarity engine in the background to automatically find connections and suggest bidirectional links as you type. Every match is ranked by a cosine similarity score — the higher the %, the stronger the connection.
🤖 Ask SuperNotes Chat — Pull up the conversational command center powered by DeepSeek's official API to query your notes, outline new articles, or refactor code instantly inside a gorgeous, non-intrusive chat window.
Every SuperNotes Online user gets a procedurally generated developer companion born with a rare 7-digit serial number, a unique name, and gorgeous neon pixel aesthetics that are entirely their own. Roll a fresh companion on every session, download a high-fidelity PNG in one click, and paste your mascot directly into X/Twitter — no uploads, no friction, just pure collectible personality living right inside your notepad.
SuperNotes Online turns your notes into a rich multimedia workspace — images, videos, and YouTube players live alongside your writing without ever touching a server.
Drag-and-drop local images and videos directly into any note, or paste a YouTube URL to instantly embed a fully interactive player — no upload, no server, no waiting.
Click any image to reveal a professional overlay with Left / Center / Right alignment controls. Drag the corner handles to resize with a live pixel-dimension label updating in real time.
Toggle between a focused Reading width for distraction-free writing and Full Width mode for rich media layouts — one click switches between the two.
Every competitor stores your data on their servers. SuperNotes Online stores it on yours.
