Introducing SlideBySide: A New Way to Present

SlideBySide allows you to present together, live and side-by-side, eliminating the need to share your entire screen.

Stop struggling with screen-sharing lag and privacy concerns. Now, everyone stays synchronized on the same slide, featuring real-time cursors, shared navigation, and collaborative drawing tools.

🚀 Quick Start Guide

Getting your presentation live is a seamless process that requires no installations, no bulky meeting software, and zero account creation for your audience.

The 3-Step Workflow:

  1. Upload your materials: Support for .pdf, .ppt, and .pptx files. You can also import directly from Google Drive or OneDrive once authenticated.
  2. Distribute the link: Anyone with the URL joins instantly. To keep things light, users are assigned a random_fun_name (which they can edit).
  3. Lead the session: Control the slide progression for the group, use your cursor to highlight points, draw on the screen, or allow participants to explore the deck independently.

🛠️ Feature Deep Dive

SlideBySide provides every tool necessary for a professional shared experience:

FeatureDescriptionBenefit
Live CursorsReal-time pointer tracking with name labels.Everyone knows exactly what is being discussed.
PermissionsGranular control over who can flip slides, draw, or download.Maintain order or encourage collaboration.
Independent BrowsingViewers can navigate away from the live slide and jump back.Allows users to review previous data without interrupting.
Presentation ModeToggle full-screen with a single keypress.Clean, focused viewing (with or without cursors).

🔐 Privacy & Management

  • Access Levels: Choose between Private (just you), Shared (specific emails), or Public (anyone with the link).
  • Version Control: Upload updated decks without losing your place. Old versions are archived along with their associated drawings.
  • Cloud Integration: Seamlessly pull content from Google Slides, Drive, or OneDrive.

📈 Example Use Case: The Q3 Review

Imagine presenting a financial slide where you highlight that: Revenue Growth=38%↑\text{Revenue Growth} = 38\% \uparrowRevenue Growth=38%↑

While you speak, your audience (e.g., BraveOtter, LunarPanda, and SwiftHeron) sees your cursor circling the growth metric in real-time.

Presenter's Checklist:

  • Upload PDF/PPTX
  • Set permissions to "View Only" for guests
  • Share link via chat
  • Trigger Full Screen mode

💻 Technical Implementation Note

The synchronization logic ensures that the state of the deck is mirrored across all clients:

// Conceptual sync logic
function onSlideChange(slideNumber) {
  broadcastToAllUsers({
    action: 'CHANGE_SLIDE',
    value: slideNumber,
    timestamp: Date.now()
  });
}
