Campaign manager for game masters
Your campaign, connected your way.
See how every NPC, location, clue and faction connects, then run the session from one screen. Find anything in seconds, and let NexusDM keep the session history for you.
No card needed. Nothing to cancel. Keep your data either way.
For D&D, Pathfinder, Call of Cthulhu or any system.
Spot thin plot threads before your players do
- Shape the campaign around your story, not a fixed template.
- Keep each arc distinct while the people and places they share stay connected.
Node types
Set up in minutes, for any system
Add ready-made types for the NPCs, locations, clues, scenes and factions every campaign has, whatever system you play. Then change them, or build your own from scratch, so your campaign is structured to suit your game.
- Start in minutes with presets for the common building blocks.
- Add the fields, states and looks your game needs.
- Nothing is fixed: every type is yours to change.
The Drowned Bell is built from the NPC, Location, Clue, Scene and Item presets.

DM screen
Run the whole session from one screen
Keep everything you need to know right in one place: easily accessible, searchable, and as compact or as verbose as you like it to be.
- Your notes, rulings and to-dos sit beside a live view of your campaign.
- Build it around how you run a table, and change it as your game changes.
- Spend the session looking at your players, not hunting through prep.
The Drowned Bell’s screen keeps the Tide Clock, the Fog & Visibility rules and a prep checklist within reach.
No card needed. Nothing to cancel. Keep your data either way.
Search
Find any name in two seconds
A half-remembered name, a detail buried in last month’s notes: find it in seconds and get back to the scene before the table loses momentum.
- Everything you have written stays within reach.
- No more pausing the game to dig through pages of prep.
Search “bell” and Ines Calloway turns up: the missing bell-ringer of St. Brine.
No card needed. Nothing to cancel. Keep your data either way.
Sessions
Last session’s recap is already written
Move the history out of your head and into automated tracking. What changed and what was discovered is recorded as you play, so you can focus on the players and their actions.
- Recap last session in moments before you start.
- Settle “wait, what happened with…?” without guesswork.
Every note, state change and bit of in-game time is logged in order, so last session’s recap is already written.
No card needed. Nothing to cancel. Keep your data either way.
Reminders
The right detail, at the right moment
Always forgetting to describe something? Let the system handle that. The right detail comes back to you at the right moment, so the important beats land when they should.
- Set it once while you prep, and trust it at the table.
- Keep your attention on the story, not on a mental checklist.
When the party reaches the Sunken Chapel, you’re reminded the bell-rope has been cut.
No card needed. Nothing to cancel. Keep your data either way.
Quick notes
Catch every idea without stopping the game
Ideas, rulings and player curveballs arrive mid-session. Capture them in seconds without breaking stride, and find them filed where they belong afterwards.
- Fast enough to use mid-sentence, so ideas don’t slip away.
- There when you need it, and quiet when you don’t.
Mid-session, file a note such as “Dunmore’s alibi” straight onto The Saltglass Ledger.
No card needed. Nothing to cancel. Keep your data either way.
World Anvil and Kanka store your lore. NexusDM helps you run it.
- Connection map first: see how everything in your campaign links together.
- A DM screen built for play, so the session runs from one place.
- Session history recorded as you go, so recaps write themselves.
Bring your NPCs and locations in by CSV
Fill in a template with your existing notes, then import it into a campaign. Columns match the NPC and Location presets, so they map automatically.
Never locked in
Your campaign is yours. Export everything as plain files at any time, even after your trial ends or you cancel.
Built by one game master, for game masters
I’m Nathan Perkins. I built NexusDM to run the campaigns I kept imagining: complex, interwoven stories that have players thinking about the campaign between sessions, not just at the table.
I didn’t want to spend my prep fighting tools and apps to get there. I wanted something that models that complexity and keeps track of everything for me, simply.
I read every email, and I’d like to hear what would make running your campaign easier.
