The DND FamilyDocumentation
One account. One membership. One shared world.
A family of connected tabletop apps over a single shared library of cards, characters, and campaigns. Sign in once; play across every site. Everything is free during beta.
The DND family is a set of connected apps for running tabletop adventures, built on one account and one membership over a single shared library of cards, characters, and campaigns. Sign in once and use whichever site fits what you're doing at the table. Each one stands alone, and together they run a whole party's game. These docs are reference-first with short task recipes — written for DMs, players, and anyone deciding whether the family is for them. Everything is free during beta.
The four sites
- DNDCards.comThe hub & card / character builder — the shared library every app reads.
- DND.chatThe AI-DM tavern: campaign chat, audited dice, an optional Autopilot DM.
- DNDWar.comTactical battle-map combat on a square grid, run with your shared characters.
- Coming soonDNDNote.comThe planned fourth site — no app yet, just a reserved corner of the world.
DNDCards.com is the hub. You build cards and characters there, and it owns the shared SRD compendium, the Homebrew Forge, and the PDF Shredder. DND.chat is where a campaign is played in text — you /summon those shared cards onto the table and roll dice that are logged and verifiable. DNDWar.com is where a fight goes tactical on a battlemap; you Invoke the same cards as tokens. DNDNote.com has no app yet — it exists only as a planned note brand, and we won't pretend otherwise.
One account, one membership
This is the whole idea: one signup gives you one identity across every site. Your campaigns, cards, characters, and dice logs are the same rows everywhere — not copies, not per-site silos. There is no separate DND.chat login or DNDWar login; the session you have on one site signs you in on the next.
A single membership covers the entire family. It is not per-site billing. During beta the Free tier is live with full access; Pro and pay-as-you-go AI credits are marked coming soon and nothing is charged today. See One Membership, Every Site for the tiers and what is always free, and How It All Connects for how the shared account works under the hood.
Use it solo, or as a group
Each tool works on its own:
- Solo prep — build cards and character sheets on DNDCards, no party required.
- A quick fight — DNDWar has a public /demo battle (a Fighter and a Wizard versus three goblins) you can try with no signup at all.
- A dice room — open a DND.chat tavern and use it as a private chat-and-dice space.
DND.chat runs fully with or without AI: a human DM can run the whole campaign by hand — async (play-by-post) or live — and the optional Autopilot DM is there only if you want one. The AI never has to be in the room.
The same campaign also wires all three together for a party. A DM preps cards and characters on DNDCards, the group chats and rolls in the DND.chat tavern conjuring those cards, and when a fight needs a map the table moves to DNDWar's battlemap using the very same characters — with HP and adventure data flowing between them. The full play-through is in Running a Connected Group Session.
