How to Become the Most Organized Game Master You've Ever Been + Track Every Detail Without Spending Hours on Prep Time Even if
Your GM Alignment is Chaotic Overwhelmed

Campaign Logger App with Automagic Tagging Slices & Dices Your Campaign For You
So You Can Focus on the Story and Being Creative

A Game-Changing GM Organization
and Campaign Management Tool
for All Modern Browsers


Our unique tagging system lets you "at" mention NPCs, location, items, plots, world details and several other categories of game info for automatic linking and cross-referencing. Tag autocomplete means you type each name in just once and then you point and click to add add every time after that.


Because each Log Entry can handle several tags, you now have instant context and cross-referencing of your notes. Want notes for each room in dungeon level 5? What about all the rooms the PCs haven't entered yet? Or how about a report on every encounter a certain NPC contact appeared in and what they said to the PCs? Need a listing of all party transactions with merchants in Waterdeep? No other app lets you cross-reference your campaign details this easily.


Prefix every log entry and campaign detail with an in-game date so you can search and review historical and backstory timelines on the fly.


Write all your ideas and notes down between sessions. Use them at the game table. And log what happens during play. You will seamlessly build an amazing and complete record of every NPC, location, item, plot, house rule, and encounter in your games. Become the most organized GM you've ever been!

Here's What You'll Get With Campaign Logger

All the features you need to get - and stay - organized with minimal effort:
Infinite Logs

Unlimited Campaign Logs. Use them for any game system. Unlimited Log Entries. Write as little or as much as you like for every campaign. You get unlimited logging.

Tag Autocomplete

Save time typing long and tricky names. Type something once and then let autocomplete tag it every time thereafter. Log sessions faster and increases note accuracy this way.

Backup, Import, Copy

Save your logs as future-proofed plain text JSON files so you never lose your data. Unlimited Campaign Log export and import. Copy & Share log entries between Campaign Logs. Create multi-campaign NPC galleries for example.

Customizable Tags

10 types of tags ranging from NPCs to treasure to Kingdoms. All tags are customizable so you can tailor each Campaign Log to match your game system and GMing style.

Search & Filter

A giant search engine for your campaign. Search any text, including tags. Search operators let you customize searches so every detail is at your finger tips.

Open in Multiple Tabs

Every NPC, item, plot, etc. gets its own URL. That means you can open log entries in multiple tabs. And you can paste Log Entry links directly into other apps you use like Evernote, MyInfo, OneNote, Google Drive, Microsoft Office, Open Office, etc. for easy cross-linking.

About the Creator of Campaign Logger

My name is Johnn Four. I'm a professional RPG author with 13 published books and three online courses on how to be a better game master. I co-wrote the Dungeon Master's Guide II, founded and anchored the GM Toolbox column in Dragon Magazine, and have been publishing the Roleplaying Tips Newsletter for GMs - 2 million words and counting - since 1999.

I created Campaign Logger with German developer Jochen Linnemann because I was having trouble organizing my detailed campaigns even with the help of apps like Evernote and MyInfo. I wanted a slick and simple way to cross-reference all my notes as I wrote them.

Apps with wikiwords seemed to have potential, but I found them cumbersome with their paging — I didn't want to create an entire page for each note, and finding notes on long pages was a pain. MyInfo, Evernote, and OneNote are awesome with document cross-linking, but it's slow — you have to right-click, choose copy, go back to your note, highlight the text and create the link.

I just wanted Twitter for RPG — fast and furious note-taking with on-the-fly tagging.

I also wanted software that was RPG-aware. Meaning, it would know an NPC from an encounter from a plot. I wanted to slice and dice my campaign notes so I would not lose another second of time questing for info buried in pages, files, or cards.

So, you could say it's my dream GMing app that does two things extremely well: it tracks all your info and keeps you organized so you can spend more brain cycles being inspired and creative instead of hunting and page flipping.

What People are Saying...

Marc Stevens ( Web Design Media )


"I'm loving Campaign Logger, and have started to incorporate loopy planning into my prep-work. Keep up the great work, with both Campaign Logger and the Tips. :)"

Jo-Herman (Senior Developer, Norway)

"During my exploration of this fine program, I've started using it for other functions outside of the basic campaign logging. Specifically, I've found that this program works really well to make custom random tables and map keys for hex crawls. I'm really enjoying this tool."

Arthur Sisneros

"I just got the email about the prefix and suffix additions, and I LOVE it!"

Is This App Right for You?

Campaign Logger is not for everybody. I have a pile of receipts over the years I could show you of stuff I regret buying. And I never want my work in your regret pile! So here's who I think this is for and not for.


  • GMs who like using digital tools to organize themselves
  • GMs who need help taking session notes and tracking campaign details
  • GMs overwhelmed by campaign prep and details — let Campaign Logger sort you out
  • GMs already using an app but want an easier way to take notes and cross-reference all the people, places, and things in your campaigns and adventures - Logger works great alongside other apps


  • GMs who already have a great organization system — keep doing what's working for you!
  • 100% Improv GMs — taking gobs of session notes will just slow you down, and using the multi-tagging and other features for campaign details is probably overkill for you
  • Epic author GMs — Log Entries can hold 300-400 words, and you get unlimited Log Entries. But you are probably best served with Scrivener or a word processor with chapter and section functionality
Critical Fumble Guarantee

I stand behind my work. Like my books and courses, the Campaign Logger has my Critical Fumble Guarantee.

If I roll a "1" and you end up not liking Campaign Logger, email me at [email protected] for a full refund, no questions asked. I'll refund you right away.

You have 30 days to play with the app and if I've critically fumbled, just email me for a refund. There's no risk to you here.

Bonus Features of the Web App

We launched Campaign Logger first to a group of beta users who helped us hone and polish the software.

Then we offered a limited-time lifetime license to my newsletter subscribers to further help us fund developer and test Campaign Logger.

You now have the benefit of thousands of hours of testing, feedback, and feature development for a smooth and fast experience logging and organizing your games.

Here are a few new features that become immediately unlocked for you when you subscribe:

3 Line NPC example
Bonus » Generators

You also get immediate access to a library of generators. Generate fantasy names, villages, NPCs, plot ideas and more for instant use in your Log Entries.

Just click on a generator, generate a result you like, and click again to instantly add the details to your notes.

More generators are being added regularly so you can prep faster or get unstuck instantly when in a pinch at the game table.


Bonus » Dice Roller Widget

Campaign Logger is widget-enabled, and the first widget we'd added is an online dice roller.

Roll multiple dice of any kind and number.

Need a d5 to see which character gets ambushed? Need FATE dice, exploding dice, or dice with formulas? Need 24d6 for an amazing area effect?

Speed up your game by rolling attack and damage for several foes at once.

At any time you can also choose to log your dice rolls and add comments! Never lose track of a roll again.


Unlimited Custom Generators
Bonus » Roll Your Own Generators

Late last year we added the ability for you to create your own generators.

This lets you totally customize your game world, your campaigns, your adventures, and even your encounters!

Build simple wandering monster tables for each hex or create complex generators with variables, weightings, and sub-tables to populate entire cities with one button click.

You can not only build any generators you want now, but you get unlimited generators. Unlimited Campaigns, unlimited Log entries, and now, unlimited Generators.
