Real-time Collaborative Document Guide

Open the app — Real-time Collaborative Document

You want to write meeting notes together during a meeting, but Google Docs asks everyone to sign in first.
If even one person has no account, that’s where it stops.
Asking people to create an account just to share a quick memo feels excessive too.

With this tool, opening the address creates a new document on the spot.
Share that address and you’re done. No sign-in, no registration.
Several people can edit at once without overwriting each other.

You can sign in with Google if you want your document list and templates kept in your account. Only those who need it have to.

How to Use

1. A new document is automatically created when you visit the page.
2. Click the Share button at the top to copy the URL.
3. Send the URL to others, and they can edit the same document simultaneously.
4. The first line of the document is automatically used as the title (large, centered).

Managing Documents

Archive

The document owner (creator) can make a document read-only using the Archive button.

• Archived documents cannot be edited by anyone.
• An Archived (read-only) badge is displayed in the presence bar.
• Only the owner can restore editing using the Restore editing button.
• Archive state changes are reflected in real-time across all sessions.

Templates (Google Sign-in)

If you type the same thing every time — a meeting-notes skeleton, say — save it as a template.
One shortcut drops it in.

• Up to 10 templates
• Shortcuts: Alt+Shift+1~0 or Ctrl+Shift+1~0 (configurable)
• Templates are saved to your Google account and synced across devices

Document List (Google Sign-in)

After signing in with Google, click the My Docs button in the top-right corner to view saved documents.

• Up to 30 documents are saved. Oldest documents are automatically removed when the limit is exceeded.
• Use the pin feature to protect important documents from automatic deletion.
• Empty documents are automatically deleted after 6 hours.

Good to Know

• Active users are shown as colored badges in the presence bar at the top.
• Other users’ cursor positions are displayed with matching colored badges in the document.
• URLs are automatically converted to clickable links after pressing space/enter.
