Introducing Cipher: Your AI Dungeon Master for D&D 5e
Learn how we're using Claude AI to revolutionize D&D campaign management and make DMing more accessible than ever.
We're thrilled to introduce Cipher & Scrollbook - a comprehensive platform that brings AI-powered storytelling to your D&D campaigns. Whether you're a seasoned Dungeon Master or just starting your journey, Cipher makes running incredible campaigns easier than ever.
The Problem We're Solving
Let's be honest: running D&D campaigns is hard work. Between session prep, rule lookups, NPC voice management, combat tracking, and note-taking, DMs spend hours on bookkeeping instead of storytelling. Players struggle to keep track of session details, and communities juggle multiple campaigns across their Discord servers.
We built Cipher to handle the mechanical parts of DMing while preserving the creativity and magic that makes tabletop gaming special.
What is Cipher?
Cipher is an AI-powered Dungeon Master that integrates directly into your Discord server and provides a companion web application (Scrollbook) for campaign management. Powered by Anthropic's Claude Sonnet 4.5, Cipher can:
- Run game sessions with context-aware storytelling and dynamic NPC personalities
- Track campaign state across sessions, remembering player choices and plot threads
- Handle rules with instant SRD lookups and context-aware applications
- Generate summaries with AI-written session recaps and highlights
- Manage characters with real-time digital character sheets
- Create homebrew with unlimited custom content creation tools
How It Works
1. Add to Discord
Invite Cipher to your Discord server with a single click. No complex configuration needed.
2. Create Your Campaign
Use /create-campaign to set up your world. Choose from preset eras (Forgotten Realms, Eberron, etc.) or create custom homebrew settings.
3. Start Playing
Invite players, create characters, and let Cipher handle the rest. The AI adapts to your party's choices, voices NPCs, tracks combat, and generates session summaries automatically.
4. Manage via Scrollbook
Access the web app for advanced campaign management, character sheets, homebrew creation, and analytics.
What Makes Cipher Different?
AI That Understands Context
Claude Sonnet 4.5's 200K token context window means Cipher remembers your entire campaign history. NPCs maintain consistent personalities, plot threads carry forward, and the world responds to player actions.
Campaign-Centric Pricing
Instead of charging per user, we charge per campaign. This means unlimited players can join without extra cost - perfect for Discord communities.
Discord Native
No context switching. Play where your community already is, with seamless Discord integration for dice rolling, initiative tracking, and turn notifications.
Homebrew-Friendly
Create unlimited custom classes, species, items, spells, and monsters. Share them across campaigns or keep them private.
Pricing That Makes Sense
We use a unique AI hour system that tracks the time Claude actively runs your game. Think of it like session time:
- Free Adventurer: 3 hours trial (perfect for testing)
- Single Campaign: $12.99/month for 10 AI hours (~5 weekly sessions)
- Multi-Campaign: $24.99/month for 20 hours across 3 campaigns
- Unlimited Guild: $49.99/month for 50 hours + unlimited campaigns
- Enterprise: Custom pricing for large communities
Unused monthly hours don't roll over, but hour packs never expire - buy them once, use them anytime.
