Campaign management for tabletop games
Your campaign, remembered.
Dungeon Ledger is a shared notebook for your tabletop campaign. Notes your players can actually see, linked into a map of your world, with the secrets kept firmly on your side of the screen.
Free to start. No card, no trial clock — one campaign as DM, unlimited as a player.
Notes
Every note carries its own visibility. Share the tavern’s floor plan with the table, keep the innkeeper’s real name to yourself, and reveal it the session it finally matters.
Players see what you’ve shared and what they wrote themselves. DM-only and secret notes never reach their browser at all — the filtering happens on the server, not in the interface, so there’s nothing to find in the page source.
Seven note types come with templates worth using: player characters, NPCs, locations, quests, session logs, secrets and plain notes.
Connections
Type [[ and start naming things. A search drops down as you type; pick a note and the mention becomes a link.
Every link becomes an edge in your campaign’s graph — who knows whom, which cult meets in which cellar, and which thread you left dangling four sessions ago. Nodes are coloured by type, and clicking one opens the note.
It’s the fastest way to answer the question every DM dreads mid-session: wait, who was that again?
The Living Book
The Living Book sits in a tab beside your notes and answers questions about the campaign, citing the notes it drew from.
It’s built so it can’t leak. The server selects the notes the person asking is permitted to read before the model sees anything, so a player’s question can only ever be answered from a player’s notes. Ask it something only the DM knows and it will tell you your information must have been taken by a False Hydra.
DMs get more rope: when the notes genuinely don’t cover something, the Book can offer outside suggestions — clearly separated from canon, and only when explicitly asked.
Safe passage for his daughter out of the city before the next tenday, in exchange for the manifest of the Sea Maiden.

The rest of it
SRD monsters, spells, races and classes are seeded on day one. Add your own homebrew alongside them.
Queue the music once as DM. Every player’s browser follows the same clock, so the drop lands at the same moment for everyone.
Seven kinds of playable puzzle — ciphers, dials, logic gates, sequences — with optional skill-check gates and hidden clues.
Propose a date, collect RSVPs, and keep the log of what happened attached to the session it happened in.
Upload your maps and pin the places that matter, linked back to the notes that describe them.
Roll without leaving the page, and keep a shared kill counter that ticks up live on every screen at the table.
* Some tools are still in development and may not yet be usable to their full capacity.
