Live note, locked for everyone but you

Everyone watches.
Only you
can type.

Write a note, turn on Classroom Mode, and share the link. Your class, audience, or team watches it update in real time — but nobody else can edit it unless they have the PIN. Built on the same real-time sync ShareNotes already uses for collaborative notes, just locked the other way.

§ Frequently asked

Answers, briefly.

What is Classroom Mode on ShareNotes?

It's ShareNotes' edit-only password protection: anyone with the link can view the note and watch it update live, but a PIN is required to edit it. Built for teachers, presenters, and anyone broadcasting text to a group who shouldn't be able to change it.

Do students or viewers need an account to follow along?

No. They just open the link. No sign-up, no app install, no email. Works in any modern browser on any device.

Will I have to re-enter the PIN every time I edit?

No. Once you enter the correct PIN on a device, ShareNotes remembers it in that browser for future visits, so you won't be prompted again on the same device.

How is this different from Google Docs view-only mode?

No account or sign-in for either the presenter or the viewers, and live updates use a websocket — viewers see each change as you type, not after a periodic refresh. There's also no separate viewer link to manage; the same link works for everyone, and the PIN is what unlocks editing.

Can a viewer just guess the PIN and edit anyway?

The PIN is a 4-6 digit code checked against a hashed value on the server, so it isn't trivially guessable in a live session, but ShareNotes has no rate-limiting account lockout — treat it like a presenter PIN, not a security boundary for sensitive data.

Is Classroom Mode free?

Yes. It's part of ShareNotes' free tier — no ads, no paid plan, no usage limit.
