NoteRoom — Collaborative Notes, No Login Required

Peer-to-peer collaborative notes. No login. No server. Your data stays yours.

Write together in real time. No account. No server. No one has your data but you. NoteRoom is a peer-to-peer collaborative notepad that lives entirely in your browser. Open a note, write whatever you want — a journal entry, a meeting log, a brainstorm, a to-do list — and when you're ready to share, generate a room key and send it to anyone. They enter the key in their own NoteRoom, and your note opens in their browser. Every edit either of you makes appears instantly on the other's screen. When the session ends, both of you keep a full local copy. Nothing was ever stored on a server. ✦ WHAT MAKES NOTEROOM DIFFERENT Every other collaborative notes tool — Google Docs, Notion, Confluence, HackMD — requires you to create an account, hand over your email address, and trust a company to store your writing on their servers. NoteRoom does none of that. Your notes are stored in your browser. Your collaboration is peer-to-peer, meaning your text travels directly between browsers — not through a middleman. When you close the session, the note lives on your device and your collaborator's device. There is no cloud copy. There is no account to delete. There is no company database containing your thoughts. This is what private, local-first note-taking actually means. ✦ CORE FEATURES Real-time collaborative editing Share a room key with anyone. They open NoteRoom, enter the key, and you're both editing the same note simultaneously. See each other's changes character by character, in real time. Up to any number of people can join the same room — no participant limit. Live presence — see who's in the room Every collaborator's name appears in the toolbar. You set your display name before joining (no account needed — just a name). See exactly who is actively in the document with you. Local-first note storage All your notes are saved to your browser's local storage. They're available instantly when you open the extension, even with no internet connection. No sync delay. No loading spinner. Your notes are just there. Clean, distraction-free writing NoteRoom uses a Notion-style rich text editor. What you type is what you see — no raw Markdown syntax cluttering your view. Format as you write: headings, bold, italic, bullet lists, numbered lists, checkboxes, code blocks. Everything you need, nothing you don't. Note sidebar All your notes are listed in a collapsible sidebar. Switch between them instantly. Your note titles are auto-generated from the first line of each note, so your list stays readable without any extra effort. One-click sharing Click the Share button to generate a short human-readable room key (like "tide-orange-71"). Copy it and send it over text, Slack, WhatsApp, email — however you communicate. The other person enters it in their extension and they're in. Notes persist after collaboration ends When the session ends or your collaborator disconnects, the note stays on both devices in its final state. No data is lost. No syncing required. It's just a local note again. No installation friction Install the extension, click the icon, start writing. There is no onboarding screen, no sign-up flow, no email verification, no subscription to manage. ✦ HOW THE ROOM KEY SYSTEM WORKS NoteRoom's room key is the heart of how collaboration works — and it's designed to be as private as possible. When you click Share, a short key is generated (example: "swift-ember-04"). This key maps to your note's unique ID on a lightweight signaling server — but the signaling server never sees your note's content. It only handles the handshake: connecting your browser with your collaborator's browser. Once connected, all note data travels peer-to-peer, directly between your devices. Room keys expire after 24 hours. After that, there's nothing to connect to — the key is gone from the server. Your note, however, remains safely on your device. This architecture means: even if the signaling server were compromised, an attacker would find nothing — no note content, no user data, no writing history. ✦ WHO USES NOTEROOM Remote teams and freelancers — Quick collaborative notes without forcing everyone onto yet another platform. Share a room key in Slack, write together, done. Journalists and researchers — Notes that never touch a company server. Sensitive interview notes, source protection, draft writing that stays local. Students — Collaborative study notes without school email restrictions or account requirements. Works in any browser on any device. Privacy-conscious users — Anyone who has ever wondered "what does this app do with my writing?" NoteRoom answers that question before you even ask it: nothing, because it never has it. Developers and technical writers — Full code block support in the editor. Write technical documentation together without a shared Google account. Writers and journalers — A clean, fast, keyboard-friendly writing environment with no distractions and no algorithm deciding what you should write next. ✦ PRIVACY — THE FULL PICTURE NoteRoom was designed around one principle: your writing is yours. — No account required, ever. Not even an optional one. — No email address collected. Not even for "account recovery." — No analytics tracking your writing habits. — No cloud storage. Notes live in chrome.storage.local — your device, your browser, your data. — No ads, no monetization model that depends on your data. — Collaboration is peer-to-peer via WebRTC. Note content goes directly between browsers. — The only server involved is a signaling server that handles connection setup. It stores room key mappings only (not note content) and these expire in 24 hours. If you want to verify any of this: the extension's source code is available for review. We have nothing to hide because we have nothing. ✦ PERMISSIONS EXPLAINED NoteRoom requests only two permissions: storage — Required to save your notes locally in Chrome's storage system. Without this, your notes would disappear every time you closed the tab. unlimitedStorage — Required to store a reasonable number of notes without hitting Chrome's default storage cap. This does not mean we access unlimited data about you — it means your notes won't get truncated if you write a lot. No other permissions are requested. NoteRoom cannot read your browsing history. It cannot access other tabs. It cannot read your clipboard without your action. It does not know what websites you visit. ✦ SYSTEM REQUIREMENTS — Google Chrome version 88 or later (Manifest V3 compatible) — Works on Windows, macOS, Linux, and ChromeOS — For collaboration: both users must have NoteRoom installed — Internet connection required only during active collaboration sessions; solo note-taking works fully offline. ✦ FREQUENTLY ASKED QUESTIONS Can I use NoteRoom without collaborating? Yes. Most NoteRoom users use it purely as a local notepad. The collaboration features are completely opt-in and hidden until you click Share. What happens if my collaborator closes their browser mid-session? The note stays open and editable on your side. When they rejoin (with the same room key, if it hasn't expired), the sync resumes automatically and they receive any changes made while they were away. Can more than two people collaborate on the same note? Yes. Anyone who has the room key can join the session. There is no participant limit. Are my notes backed up anywhere? Notes are stored in Chrome's local storage — on your device. If you clear your browser data or uninstall Chrome, notes will be deleted. We recommend periodically copying important notes to a text file. Cloud backup is not a feature, by design. Does NoteRoom work on incognito mode? Chrome extensions have limited storage access in incognito mode by default. You can enable NoteRoom in incognito via Chrome's extension settings, but notes created there won't persist after the incognito session ends. Will you add mobile support? NoteRoom is currently a desktop Chrome extension. Mobile browser extension support depends on Chrome for Android's extension API, which is limited. We're watching that space closely. Is this open source? Yes. The source is available for review. We believe privacy tools should be auditable. NoteRoom — because your thoughts don't need an audience you didn't invite.
