Your co-DM,
for the long campaign.

Scrollbook helps you plan sessions, manage encounters, keep up with your players, and fill in when Barb is sick on campaign day. Use the AI as much or as little as your table likes.

Elara takes 14 piercing from the trap. She's bloodied. The vault doors groan shut.
The Compendium

Three tomes. One co-DM.

Use what serves your table. Ignore the rest. Scrollbook scales from light bookkeeping to a full narrated experience. You decide where the line sits.

Discord-native

A bot that knows your party.

Drop Scrollbook into your Discord and it tracks character stats, applies damage and conditions, and updates sheets in real time. No tab-switching, no spreadsheets.

  • Auto-updates HP & spell slots
  • Reads from your character sheets
  • Dice rolls with full modifiers
Worldbuilder

A planner for homebrew worlds.

Build cities, factions, and questlines with a structured campaign canvas. Link NPCs to locations, locations to plots, plots to sessions. Everything stays connected and nothing gets lost between games.

  • NPC + location encyclopedia
  • Session prep templates
  • Plot threads that follow you forward
Autopilot

An AI DM, when you need one.

Hand the reins to Scrollbook for a one-shot, a side quest, or a full session. It narrates, manages inventories, generates NPCs on the fly, and hands the table back when you're ready.

  • Voice-aware narration
  • On-demand NPC generation
  • Inventory & loot tracking
The Ritual

From cold start to first session in an hour.

No onboarding wizard. No 40-minute tutorial. Scrollbook reveals itself as you play.

  1. Light the candles.

    Connect your Discord and create a campaign. Import characters from D&D Beyond or roll fresh ones inside Scrollbook.

  2. Sketch the world.

    Draft sessions, drop NPCs, sketch locations. Scrollbook keeps every thread linked so prep takes minutes, not evenings.

  3. Choose your assist.

    From silent bookkeeping to full narration, slide the AI dial to wherever your table likes it. Change it any session.

  4. Roll initiative.

    Run the session. Scrollbook tracks HP, conditions, loot, and spell slots in the background. You stay in the story.

A Glimpse Inside

Built like a leather binder. Runs like a co-DM.

Every screen feels like a page from your table's tome: quiet, considered, and dense with the things you actually need at game time.

Three plot threads remain open from Session 6: the merchant's debt, Vex's patron, and the moonstone shard. Want me to draft a hook for tonight that ties at least two together?
A Note from the Bench

“Barb was sick. The session almost died.”

We'd been running our campaign for two years. Then Barb, our healer, our note-taker, the one who actually remembered who the duke's daughter was, caught the flu the morning of session twelve. Nobody wanted to cancel. Nobody wanted to play without her either.

So I MacGyvered something: a Discord bot that knew her sheet, a notes doc the rest of us had been ignoring, and a fragile Python script that pretended to be Barb's bard for one night. It mostly worked. The party laughed. The story moved.

Scrollbook is what that hack grew into. A co-DM that handles the bookkeeping when you want it to and disappears when you don't. The table keeps playing, even when life gets in the way.
