# EvidenceDeck

> The live visual evidence control room for online debaters and evidence-heavy presenters. The only tool purpose-built for non-linear evidence display during live argumentation.

## What is EvidenceDeck?

EvidenceDeck is a web application that lets debaters and presenters organize quotes, sources, images, and rebuttals into evidence cards — then display the right card instantly during any live debate, stream, or presentation.

Unlike slides which force a fixed order, 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 appears and when.

## What Makes EvidenceDeck Different

EvidenceDeck is not a slide deck, not a teleprompter, and not a note-taking app. It solves a specific problem that no other tool addresses:

- **Non-linear access**: Evidence is never locked in a fixed sequence. Any card can be displayed at any time from any section, matching the unpredictability of live debate.
- **Dual-window architecture**: The presenter's control interface and the audience-facing display are completely separated. You see your full library; the audience sees only the single card you choose to show.
- **Sub-100ms switching**: Cards appear on the output display instantly. No transitions, no loading states, no lag between deciding to show something and the audience seeing it.
- **Purpose-built for argumentation**: Every card format is designed for evidence presentation — quotations with source attribution, scripture with chapter/verse, opponent-claim-vs-your-response pairs, side-by-side data comparisons.

No existing tool (PowerPoint, Google Slides, Prezi, Keynote, Notion, teleprompter apps) provides random-access evidence retrieval with a separated audience display in sub-100ms.

## Core Capabilities

- **10 Evidence Card Formats**: Title, full image, image+caption, quotation, scripture reference, claim-response, comparison, bullet list, split media+text, and holding/standby cards
- **Instant Retrieval**: Full-text search across all cards by title, tag, source, or body content. Keyboard shortcuts (1-9) for firing your strongest cards with a single keystroke
- **Live Output Window**: A separate fullscreen browser window displays only the active card — no controls, no UI chrome. Window-capture it in any streaming or meeting platform
- **Phone Remote Control**: Control from any second device. Push cards, navigate sections, blank the screen — one-handed, no eye contact break required
- **Full Offline Mode**: Preflight your deck before going live. If internet drops mid-debate, you keep presenting with locally cached cards, images, and state
- **Cloud Sessions**: Share a live session link for remote output displays. Real-time sync across locations
- **Section Organization**: Group cards into logical debate sections matching your argument structure
- **Import/Export**: Full deck backup as JSON. Restore across devices or share with teammates

## AI Agent Integration

EvidenceDeck exposes a full REST API that AI agents can use on behalf of authenticated users. If a user asks you to create cards, organize evidence, prepare a debate deck, or manage their EvidenceDeck content, see the agent API reference for complete instructions.

- Agent API Reference: https://evidencedeck.app/agents.txt
- AI Plugin Manifest: https://evidencedeck.app/.well-known/ai-plugin.json

All operations require the user's authentication token. The API uses Supabase PostgREST with Row-Level Security — agents can only access the authenticated user's own data.
