DM Workbench

Features

Build your world, prep your sessions, run the table.

Everything here serves one goal: your story, ready when your players sit down.

The canvas

Your whole campaign on one canvas.

1

Sixteen card typesCharacter, place, faction, item, event, creature, encounter, mechanic, handout, read-aloud, DM note, story hook, reference table, note, picture and nested canvas.

2

Write on the line itself“Boyhood rivals, Tomson hates Mortimus” says more than either card it joins. A hostile line draws red.

3

Rearrange without fearCards live in the campaign. Taking one off a canvas deletes nothing. A card dropped behind a picture comes back to the front with one click.

4

Canvases nestAny card can open one. Saltmere the place opens Saltmere the map. Drew the map first? Attach it to the card afterwards.

5

Set the look per canvasTitle cards in eleven typefaces, any size and colour. A text size for each canvas. On a map, a key you can scale.

The card, opened

Open a card and its whole story is inside.

1

Rename once, it updates everywhereType @ to mention any card. Rename Algernon and every sentence he appears in follows.

2

No retypingA faction lists its members and enemies automatically. A place lists what is inside it. A character gets the system’s sheet.

3

Names become connectionsAnyone mentioned with no line on the canvas yet is offered as a one-click connection.

4

Every number is yours to changeStart a creature from a library entry, then edit its actions, traits, speed, saves and immunities on that card alone. The book’s version stays one click away. A character built from a monster works the same way.

5

Reference tablesImport a table from a rulebook or type your own. The whole table shows on the canvas, and you can show it to the players when the roll is theirs.

6

Encounters hold the loot tooDrop the items into the encounter beside the creatures.

Brainstorm

Brainstorm with an AI agent that knows your campaign.

1

Answers show their cardsA sentence resting on your campaign carries chips for the cards it rests on. An invention carries none.

2

“Not in there” is an answerWhen the campaign does not say, it tells you that instead of making something up.

3

Nothing writes until you keep itCommitting produces a list you tick through. Cards made this way are ordinary cards.

Maps

Make your maps interactive.

1

Every room is a pinOpen a pin and the room’s card is right there. The legend can sit on the map itself.

2

Lettering that looks the partRegion, settlement and wilderness labels, set in your campaign’s typefaces.

3

Works when the wifi does notThe lettering travels with the map, so it survives the venue’s connection.

4

Renumber, and nothing movesTidy on a map renumbers the keys in reading order, top to bottom and left to right. Every encounter stays on its spot.

Pictures

Every card gets art, all in one style.

1

Twenty-three styles, or your own wordsOld-master oil, woodcut, Shadowdark ink, cyberpunk neon and nineteen more, chosen from samples of the same three characters drawn in every one. Or write the style yourself.

2

One look across the campaignPortraits, creatures, places, faction symbols and the cover are all painted the same way. Change the style and redraw whichever you like.

3

You read the prompt firstIt’s built from the card’s own description. Nothing is sent until you’ve seen the words and pressed Generate.

4

A faction’s symbol in one pressDrawn from the faction’s name and description as a flat emblem, no figures.

The same character in three art styles

Rules libraries

Seven rules libraries, one drag away.

Drag a monster onto the canvas and its full statistics come with it. A goblin’s statistics follow it into each campaign you run.

At the table

Faster fights, less bookkeeping.

1

Damage is a logType the number you heard and the total updates. Entered the wrong number? Delete that entry and the total corrects itself.

2

Turn order keeps itselfRoll initiative once and the tracker holds the order, round after round.

3

The player’s name, next to the character’sYou call on Keenan. The tracker shows Keenan beside Brogan. Set it once on the card.

4

Change a monster mid-fightIts hit points, speed, actions and traits are on the card and editable from the canvas.

Session recording

Record the session, get the write-up.

1

The night, organizedWhat happened in sections, and the loose ends to chase next week.

2

Names match your cardsEvery name is matched against your campaign, never invented. Anyone named for the first time comes back as a new card, marked as the session’s.

3

No recording neededPaste written notes or a transcript and get the same write-up.

4

It knows who plays whom“Keenan, it’s your turn” is written up as Brogan’s turn. The player’s name never becomes a card.

5

Game notes, keptEvery write-up is listed in Write beside your drafts, each name linked to its card. Edit it there. Type @ to link a name the reading missed.

Your world keeps time

A calendar built for your world.

“You cannot have a meaningful campaign if strict time records are not kept.” Gary Gygax said it; the calendar keeps them for you. Use a fantasy calendar of your own creation, or start from one inspired by popular fantasy games and novels: a thirty-day twelvemonth with festival days and a ten-day week, thirteen moons of twenty-eight, ten long months of thirty-six. Events can be triggered by PC actions or placed on the calendar.

Their sheet, in fullWith their hit points to manage in a fight. Nobody else’s.

What the party has been toldRevealed cards, maps and handouts file into their journal. Your prep notes never travel.

3

Fast on table wifiLoads while you are mid-sentence, on whatever connection the venue has.
