EvidenceDeck — Live Debate Evidence Control Room

The only tool built specifically for displaying evidence instantly during live debates. Not a slide deck. Not a teleprompter. A control room.

The Problem EvidenceDeck Solves

Slides force a fixed order. Debates don't. When your opponent raises something unexpected, you need a specific quote, a comparison chart, or a scripture reference immediately — not in 15 slides, not in another tab, not from memory.

EvidenceDeck keeps your entire case loaded and ready. Pull the card you need the moment you need it. The audience sees clean, formatted evidence on a separate display. You stay in control of what they see and when.

What Makes EvidenceDeck Unique

• Non-linear evidence retrieval — Unlike PowerPoint or Google Slides, evidence is not locked in a fixed sequence. Access any card from any section at any time.
• Dual-window architecture — Your control interface and the audience display are completely separated. You see everything; they see only what you choose to show.
• Sub-100ms card switching — Cards appear on the output display before your sentence ends. No loading screens, no transitions, no lag.
• Purpose-built for argumentation — 10 specialized card formats designed for evidence presentation: quotations with source attribution, scripture with chapter/verse, claim-response pairs, side-by-side comparisons, and more.
• Works without internet — Full offline mode. Preflight your deck before going live. If connectivity drops, you keep presenting.
• No new software for your audience — Works with OBS Studio, Zoom, StreamYard, YouTube Live, Google Meet, X Spaces, Riverside — any platform that can capture a browser window.

Key Features

• Instant Search — Full-text search across all cards by title, tag, source text, or body content. Find any card in milliseconds.
• Keyboard Shortcuts (1-9) — Assign your strongest evidence to hotkeys. Fire them with a single keystroke mid-sentence.
• Phone Remote Control — Control the presentation from your phone or tablet. Push cards, navigate sections, blank the screen — one-handed, no eye contact break.
• Sections and Organization — Group cards into logical debate sections. Switch entire arguments with one click.
• Cloud Sessions — Share a live session link. Your remote display stays in sync across devices and locations.
• Offline Preflight — Verify all assets are cached before going live. Built-in diagnostics confirm readiness.
• Import and Export — Back up your entire debate as JSON. Restore across devices or share with teammates.
