About
An outliner is a text editor built around one simple idea: every thought is a bullet point, and bullet points can be nested inside each other. Instead of writing long, flat documents, you capture ideas as short lines, indent details under the topics they belong to, and collapse branches you are not working on. The result is a living tree of your thinking — one that you can reorganize in seconds as your understanding grows. Writers use outliners to structure articles before drafting them, engineers use them to break projects into tasks, and students use them to take layered lecture notes where big concepts sit above supporting details.
NNote is an outliner designed around a second idea: your notes should belong to you. Most modern note apps store your writing on a company server, require an account, and stop working when your connection drops. NNote takes the opposite approach. Everything you write is saved directly on your device, the app works fully offline, and when you want your notes on another device, they travel peer-to-peer between your own machines: a signaling service only helps the two devices find each other, but your note content itself is never sent to or stored on any server. There is no sign-up, no subscription, and no lock-in: your entire notebook can be exported as plain Markdown files at any time.
NNote also brings modern AI to this private-by-design architecture. Using Chrome's built-in on-device model, NNote can search your notes by meaning rather than exact keywords, summarize long outlines, and suggest tags — all computed locally, so the privacy promise is never broken. You get the convenience of an AI-assisted knowledge base with the peace of mind of a paper notebook that never leaves your desk.
Getting Started
From a blank page to a synced, searchable knowledge base in four steps.
NNote runs entirely in your web browser — there is nothing to install. Click "Start Writing" and the editor opens immediately. Because all data is stored locally in your browser using IndexedDB, no account registration or sign-in is required. You can also install NNote as a PWA (Progressive Web App) from your browser menu to launch it like a native app.
Press Enter to create a new line and Tab to indent it under the line above. Shift+Tab moves a line back out. On mobile, swipe right on a line to indent and swipe left to outdent. Every line becomes a node in your outline tree, and you can collapse or expand any branch to hide details while you think about the big picture.
Use #tags to categorize notes and [[wiki-style links]] to connect related topics. NNote automatically builds backlinks, so you can always see which notes reference the one you are reading. Type !! to insert a date from a calendar picker — useful for journals, meeting notes, and task deadlines.
When you want your notes on another device, open the sync panel on both devices and connect them peer-to-peer over WebRTC — your notes travel directly between your devices without passing through a server. You can also sync to your own Google Drive, or export everything as Markdown files in a ZIP archive at any time.
Use Cases
An outliner is a general-purpose thinking tool. Here are the workflows where NNote shines.
The date picker (!!) and date-based search make NNote a natural fit for chronological notes. Capture decisions during a meeting as nested bullet points, tag them with the project name, and find them later by date or tag — even when you are offline on a train or plane.
Outlines are ideal for breaking a large goal into smaller steps. Start with the project name as a top-level node, add milestones beneath it, then break each milestone into concrete tasks. Zoom into a single branch when you need to focus, and drag items around as priorities change.
Connect concepts with bidirectional links to build your own wiki. When you write a note about a new topic and link it to related notes, backlinks accumulate automatically — over time your notes become a networked knowledge base you can explore, with on-device AI search to find ideas even when you forget the exact words you used.
Many writers plan in outlines before writing prose. Sketch the structure of an article as nested points, reorder sections by dragging, then flesh out each point with Markdown formatting. When the draft is ready, export it as Markdown and paste it into your publishing tool.
FAQ
Answers to common questions about pricing, privacy, and how NNote works.
Yes — NNote is free to use, with no paid tiers, feature limits, or trial periods.
All notes are stored locally in your browser using IndexedDB. Nothing is uploaded to servers — NNote has no accounts or database of users. P2P sync transfers data directly between your own devices over an encrypted WebRTC connection. You can optionally sync to your own Google Drive, where files are stored in your account and visible only to you.
Because notes live in browser storage, clearing site data for NNote will delete them. To protect your work, consider performing optional Google Drive sync or periodically exporting to Markdown ZIP so you always have an offline copy. Drive sync also keeps up to five dated snapshots from the last month, so a bad merge can be undone from the sync settings. If you use NNote on two devices with P2P sync, the second device also acts as a natural backup.
Yes. NNote is an offline-first PWA — after your first visit, the entire app is cached on your device and works without any network connection. You can read, write, and organize notes on a plane or in the subway, and sync whenever you are back online.
NNote uses the Chrome built-in Prompt API (Gemini Nano), which runs a language model directly on your device. AI search, summarization, and tag suggestions are all computed locally — your notes never leave your machine. This feature requires a recent version of Chrome with on-device AI support; NNote works fully as an outliner without it.
NNote implements WebMCP, an emerging web standard that lets AI agents interact with web apps through structured tools instead of clicking around the UI. When you use a WebMCP-capable agent, it can list, search, read, create, update, and organize your NNote notes directly. Notes an agent accesses are shared with that agent — and with its AI model, which may run in the cloud — so connect only agents you trust. Without an agent, NNote works exactly the same as before.
NNote works in modern browsers on Windows, macOS, Linux, Android, and iOS. The outliner, offline mode, sync, and export work across all of them. On-device AI features are currently available in Chrome on desktop. Touch gestures like swipe-to-indent are designed for phones and tablets.
Your data is never locked in. NNote stores outlines as plain structured text with Markdown support, and the export feature produces standard Markdown files in a ZIP archive that any editor can open. This means you can move to another tool at any time. The goal is for NNote to be useful enough that you choose to stay, not to trap you in.
The biggest difference is architecture: NNote has no server and no account. Most outliners store your notes in the cloud and require sign-up; NNote keeps everything on your device and syncs peer-to-peer. It also adds on-device AI search and generation, which cloud tools typically perform on remote servers. If privacy, offline access, and data ownership matter to you, that trade-off is the whole point of NNote.
NNote stores everything locally on your device. No accounts, no servers watching your notes. Sync only when you choose to — peer-to-peer, direct.
