for the game master who prepped nothing

The paid plan puts your party in every tool, reads full character sheets from screenshots, connects your AI assistant (Claude, ChatGPT and other MCP apps) through our MCP server, adds the AI tools and saves everything to your account, on every device.

“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.
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.
Initiative in, combat out. Never lose whose turn it is.
319 spells and all 15 conditions, searchable in one keystroke.
All 334 SRD monsters, searchable. Open a stat block from anywhere a monster appears.
Eight goblins attack. Every d20 and every damage die, in one click.
A real rigid-body d20. It bounces, it lands crooked, it sounds right.
When the monster crits. A hundred outcomes across six tiers of bad.
Crits worth describing, from a telling blow to a fatal strike.
Six d100 tables. 600 ways it goes wrong, written by hand.
Nat 1 on a save or a check. Six d100 tables by ability.
Eighteen d20 tables — one per skill. The only table here with good news.
They went left. A name, a shop, a tavern, a street, a rumour — one click each.
Days on the road, one line each: the weather, what you pass, and whatever finds you.
They opened the door. What's behind it, sized for your party, in one click.
Your parties, saved. Every tool knows who's at the table.
Three hours to game and no plan. Press the button.
The shape of one evening, on one page. Threads carry over.
Is this fight going to kill them? Answered before you run it.
CR-appropriate treasure with flavour text, ready to paste into your VTT.
The player asked the barkeep's name. You have eight seconds.
A runnable encounter with read-aloud text, DCs and a hint ladder.
Describe a room, get art for it. Cast it to the TV in one click.
The rest have their own pages.
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.
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 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.
Your whole party, read from their sheets, and a planning partner that can see it — through DnD Gadgets' own MCP server.
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.
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.

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.
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.
Improv Tables names it. One tap paints the sign over the door, lettering and all, and it stays pinned with the name.
Save them from the NPC Generator and draw their face. Next session they're still there, and so is the face.
Dungeon Room paints what the players can see — never the trap — and puts it up full screen for the TV.
The free tools stay free. This is what the paid plan adds, for less than a set of dice.
30-day refund on request, no argument.
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.
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.
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.
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.
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.
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.
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.
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.
A person. There is no ticket system and no chatbot — it's a support address that reaches whoever built the thing that broke.
Set the party up once before then.
