“You already have eleven tabs open.” A dice roller from one site, a spell list from another, initiative on paper, and a party you retype every week. None of them know about each other. These do.

Contents

Twenty-one tools, grouped by when you reach for them. The 15 marked free open straight into the working tool, no sign-up; the rest are on the subscription.

In combat

Combat Tracker free

Initiative in, combat out. Never lose whose turn it is.

Spell & Condition Lookup free

319 spells and all 15 conditions, searchable in one keystroke.

Monster Lookup free

All 334 SRD monsters, searchable. Open a stat block from anywhere a monster appears.

Mob Attack Roller free

Eight goblins attack. Every d20 and every damage die, in one click.

3D Dice Roller free

A real rigid-body d20. It bounces, it lands crooked, it sounds right.

When the dice betray you

Monster Critical Hit Tables free

When the monster crits. A hundred outcomes across six tiers of bad.

Player Critical Hit Table free

Crits worth describing, from a telling blow to a fatal strike.

Critical Fumble Tables free

Six d100 tables. 600 ways it goes wrong, written by hand.

Nat 1 Tables free

Nat 1 on a save or a check. Six d100 tables by ability.

Nat 20 Skill Tables free

Eighteen d20 tables — one per skill. The only table here with good news.

When they go off-script

Improv Tables free

They went left. A name, a shop, a tavern, a street, a rumour — one click each.

Travel Montage free

Days on the road, one line each: the weather, what you pass, and whatever finds you.

Dungeon Room free

They opened the door. What's behind it, sized for your party, in one click.

Between sessions

Party Manager

Your parties, saved. Every tool knows who's at the table.

Session Generator

Three hours to game and no plan. Press the button.

Session Prep Sheet

The shape of one evening, on one page. Threads carry over.

Encounter Builder free

Is this fight going to kill them? Answered before you run it.

Treasure Generator free

CR-appropriate treasure with flavour text, ready to paste into your VTT.

NPC Generator

The player asked the barkeep's name. You have eight seconds.

Puzzle Generator

A runnable encounter with read-aloud text, DCs and a hint ladder.

Scene Art Generator

Describe a room, get art for it. Cast it to the TV in one click.

Three of them, up close

The rest have their own pages.

One party, every tool

On the paid plan you enter your party once. The Combat Tracker pulls them in with a button, and a natural 1 in the dice roller opens the right fumble table already knowing whether that character swings a sword or casts a spell.

That shared party is the thing a free single-page tool structurally cannot do.

Initiative order with the party loaded and the active turn highlighted.

2,000 hand-written outcomes

Six d100 fumble tables, six more for natural 1s on saves and ability checks, eighteen d20 tables for natural 20s on skill checks, and crit tables for both sides of the screen.

Written by hand, graded into named severity tiers, and — because severity that is only a colour is no severity at all — every row says which tier it is.

Every one of them is free to read, and the dice roller and the tables roll free too, no account needed. The paid plan adds the party: it picks the table for whoever rolled.

A rolled fumble result showing its severity tier, effect text and the browsable table beneath.

The eight seconds after "what's his name?"

A full NPC — voice, mannerism, ideal, bond, flaw and three lines of dialogue you can read aloud — from a role and a mood. Puzzles come with read-aloud text, DCs and a hint ladder. Scene art casts to the TV in one click.

A generated NPC sheet with appearance, personality triad and dialogue hooks.

Plan your next session with your AI assistant

Your whole party, read from their sheets, and a planning partner that can see it — through DnD Gadgets' own MCP server.

The whole character sheet, from screenshots

Screenshot the sheet in your VTT or character builder and drop the images on the character. DnD Gadgets reads them into a full sheet — abilities, skills, attacks, spells, features, inventory — and shows you what will change before anything is saved.

When they level up, add the new screenshots. You see exactly what moved — “Level 8 → 9, gained a Cloak of Protection” — and every change is kept as a dated history.

A character's Character Sheet page: ability scores and saves, combat stats, identity, skills and features.

It already knows the party

DnD Gadgets runs a hosted MCP server — the Model Context Protocol AI assistants use to reach outside tools. Connect it to your account and Claude, ChatGPT or any MCP app can read your parties, each character's full sheet and what changed since last level, your prep sheet and the threads still open, your saved NPCs and the fight in progress.

Ask it whether a fight is too much and it rates it with the Encounter Builder's own numbers, against your party's real levels — not a guess.

  • A real MCP server. One web address with a proper sign-in. Nothing to install, no API key to copy around.
  • Saves only where you'd expect. It reads everything, and saves only to your prep, NPCs and encounters. Every change is labelled and can be undone.
  • Two clicks. Paste one address into your assistant, choose Allow here. Disconnect any time from your account.
  • Included. Nothing extra to pay us. You need an assistant that supports custom connectors, such as Claude or ChatGPT.

Step by step: add it to Claude or to ChatGPT.

You

What's changed on Vraxxis since last session — and are four ogres too much for the party?

Claude

Vraxxis is level 9 now: 122 HP, AC 19, and an attuned Cloak of Protection. The bell thread on your prep sheet is still open. Four ogres against your four level-9 characters rates Easy on the Encounter Builder's numbers — add a hill giant and it's Hard.

An example.

Every monster has a face

A woodcut portrait for all 334 monsters in the SRD, free in Monster Lookup — and, on the paid plan, a sign or a face for anything your players invent on the night.

The tavern they just walked into

Improv Tables names it. One tap paints the sign over the door, lettering and all, and it stays pinned with the name.

The NPC they won't stop talking to

Save them from the NPC Generator and draw their face. Next session they're still there, and so is the face.

The room they just opened

Dungeon Room paints what the players can see — never the trap — and puts it up full screen for the TV.

Questions

Which tools are free?

15 of them work with no sign-up, no card and no trial: Combat Tracker, Spell & Condition Lookup, Monster Lookup, Mob Attack Roller, 3D Dice Roller, Monster Critical Hit Tables, Player Critical Hit Table, Critical Fumble Tables, Nat 1 Tables, Nat 20 Skill Tables, Improv Tables, Travel Montage, Dungeon Room, Encounter Builder and Treasure Generator. You type your party in by hand and your work is kept in your browser. The paid plan adds your saved party, full character sheets, the AI assistant connector, the AI tools and saving to your account, on every device.

Do I need a card for the trial?

Yes. Seven days, then $3.99/month unless you cancel. You can cancel from your account page at any point during the trial and you will not be charged.

Is this official?

No. DnD Gadgets is an independent product and is not affiliated with, endorsed, sponsored or approved by Wizards of the Coast. The tools are 5e-compatible. Spell and condition reference text comes from the SRD 5.1 under CC-BY-4.0 — see licences.

Is the art AI-generated?

Yes. The monster portraits, tavern signs, NPC faces and scene art are generated by AI image models, then cleaned into line art and, for the bestiary, checked one by one. They aren't official artwork or taken from any book — see licences. The crit, fumble, nat 1 and nat 20 tables are written by hand.

Will it work on my phone at the table?

Yes. Every tool is built for a phone first, including the 3D dice roller, which falls back to a styled non-WebGL roll on hardware that can't run it.

Is there a DnD MCP server for my campaign?

Yes: DnD Gadgets is one. It's a hosted MCP (Model Context Protocol) server that lets your AI assistant read your parties, each character's full sheet and its change history, your prep sheet, saved NPCs and items, and the fight in progress — plus a tool that rates an encounter's difficulty against your party's real levels. It can also save to your prep sheet, saved NPCs and encounters, never your parties or sheets, and every change can be undone. Characters come in from screenshots of whatever VTT or character builder you use, so there's nothing to export or link. It's built for any MCP client — tested with Claude.

What do I need to connect an AI assistant?

A DnD Gadgets subscription and an assistant that supports custom connectors or remote MCP servers, such as Claude or ChatGPT. On your account page, copy the connector address, add it in your assistant, and choose Allow when DnD Gadgets asks. It reads everything but saves only to your prep sheet, saved NPCs and encounters, never your parties or sheets. Every change is labelled and can be undone from your account page, and you can disconnect it there at any time.

What happens to my data if I cancel?

You keep access until the end of the period you paid for. Your data stays after that — nothing is deleted on a schedule — so it is all still there if you come back. You can delete your account and everything in it yourself, at any time.

Who do I email when something breaks?

A person. There is no ticket system and no chatbot — it's a support address that reaches whoever built the thing that broke.

Your next session is on a Friday

Set the party up once before then.
