Your campaign lives in three browser tabs
and a notebook you can't find.

Notion for the wiki. Roll20 for combat. Discord for everything else. A note app for the names. The notebook for the rest. We've been there. We built one tool to hold the whole thing.

Worldbuilding

A world that links itself.

NPCs, settlements, factions, lore, quests, encounters — typed, linked, searchable. Type @ in any note and the world autocompletes.

Innkeeper at @Black Stag in @Saltmere

She owns the Black Stag because her husband owned it, and her husband owned it because @the Lampreys let him.

DM Assistant

An AI your campaign trained.

Entirely optional — skip it and the rest of the app doesn't change. But if you want a co-DM: retrieval over everything you've written, a witness to the Lamp Grove murder whose voice matches your lore, and nothing touches your world until you click Save. You're always in control.

Read the technical post
Give me a witness to the Lamp Grove murder, but make them unreliable.
A reed-cutter named Onnen Wick, sixty-three. He saw a man in Order vestments — but his eyes have gone the way of his mother's. He is, however, certain about the sound.

A note from the maker

“I'm building Dungeon Diary because I needed it. When I moved away from my home group, remote play got hard — our DM didn't have the technical chops for Foundry, and I was drowning trying to flesh out a homebrew campaign across Notion pages and notebooks. I wanted one place that made it easy to organize a campaign and run it well, whether the party's around the table or scattered across timezones.”

— Matt · Building Dungeon Diary in public
Questions

Things worth asking.

Do my players pay?
Do I have to use the AI?
What's the AI built on?
Can I import from Obsidian, Notion, or D&D Beyond?
Is the 5e SRD included?
What if I cancel?
When does it launch?

More on the beta page and in the blog.

The session is in six days.

Open a campaign in two minutes. Run the table from one tab.
