Your notes. Your browser.

THREE THINGS WORTH KNOWING

01

Your notes never leave your browser.

Everything is saved in Chrome's local storage on your device. We have no database, no cloud, no server holding your writing.

02

Collaboration is direct. Peer to peer.

When you share a note, the content travels between browsers — not through us. A signaling server handles only the connection handshake, never your text.

03

No account. No email. No setup.

Install it, click the icon, start writing. Collaboration requires nothing but a room key you share with the other person. That's everything.

NOTES

A notepad that's always there.

Journals. Meeting logs. Brainstorms. To-do lists. Code snippets. NoteRoom handles all of it. Your notes are stored locally and open instantly — no loading screen, no sync delay, no internet required.

COLLABORATION

Share a key.
Write together.

Click Share, get a short room key — something like "soft-frost-35". Send it over Slack, WhatsApp, text, or email. The other person enters it in their NoteRoom and your note opens in their browser. Every edit either of you makes appears instantly on the other's screen.

You click Share → Room key generated → They enter key → synced
Real-time sync No participant limit Key expires in 24h

For anyone who has ever wondered what a notes app does with their writing. NoteRoom's answer: nothing.

Questions.

Yes. Solo note-taking is fully offline. Your notes open instantly from local storage. Collaboration requires an internet connection only during the active session.
Notes are stored in Chrome's local storage. Uninstalling the extension removes that storage. We recommend copying important notes to a text file periodically. Cloud backup is not a feature — by design.
Yes. Anyone with the room key can join. There's no participant limit.
Only the connection handshake — not your note content. It stores a mapping of room key to note ID and forgets both after 24 hours.
Yes. No free trial. No freemium limit. No account needed to unlock anything. The full product is free.
It's open source. You can review exactly how it works on GitHub. We have nothing to hide because we store nothing.

Your writing belongs to you.
Not to a server.

NoteRoom is free, open source, and built around one idea: your notes should stay exactly where you put them.
