DSA, D&D or House Rules: Why Atlavium Is System Agnostic
A wizard does not have the same values in every system. Her story still needs a place. How Atlavium keeps world knowledge and game rules apart.

An airship for your role-playing worlds
Your Atlavium is a magical airship for your role-playing worlds. Gather characters, maps and stories, connect your knowledge and bring it to your next game night.
Your Compendium stays free within your granted allowance. Access & costs
Your Atlavium carries your worlds. Each Realm has its Compendium. You decide what becomes Canon.
Connected world knowledge
Who was Mira Fenn? Where did you meet the cartographer? Why is she looking for a missing sea chart? In Atlavium, entries do not have to stand alone. Connect people with places, relationships, events and the notes behind them.
The tour follows a fictional example Realm, showing how the different parts support the same small adventure.

Give each idea a suitable home. Start with the tools your world needs right now.
For your next game night
Keep campaigns and quests together, prepare your next session and write the recap afterwards. Characters, places and notes stay connected to your world.


Your librarian aboard
The Keeper is the old, wise and friendly librarian aboard your Atlavium. He watches over your Compendium, helps you look things up and follows the threads of your stories with you.
Ask him about the knowledge in your current Realm, and he will show you the sources behind his answer. Even a wise librarian can be mistaken: you decide what becomes Canon. His company is there when you want it.

Choose what you want to share. Your fellow players bring that content into their own Realms. They keep it there even if you stop sharing later.
Download your Realms with their notes, images and files. You can read your stories outside your Atlavium, too. The export format is open.
Hi, I’m Denis.
From Nikolassee, with a love for role-playing.I’m Denis, and I build Atlavium in Nikolassee, Berlin. It began with my game master’s OneNote notebooks: plenty of knowledge, but finding the right detail was another matter. Today my own character journal and my group’s stories travel aboard too.
Have an idea, found a snag, or just fancy a chat about your game? Drop by Discord. I’d love to meet you.

On large screens, things that belong together now sit side by side. Sessions track Quests and tasks, and Play mode keeps your notes at hand.
See all changesCompendium features remain free within your granted allowances, and those allowances will not be reduced. Atlavium is my hobby project, so I cannot give everyone unlimited space. If you need more room, have a chat with me about a possible increase.
AI features use credits because they have the highest running costs. Starting with version 1.8.0, I’m providing everyone with 500 AI credits. The app shows your current allowances and available credits. Find out more on the costs and access page.
No. You can organize your Realms, notes and sessions without his help. If you like, your Keeper can help you look things up and bring together knowledge from your Realm. He is the friendly librarian aboard your Atlavium.
No. Atlavium keeps your group’s knowledge together and helps you prepare. You play at the table or in your VTT. Use Whiteboards to arrange maps and clues. Atlavium does not run combat or offer shared live play.
Drop by Discord and have a chat with me! I’m Denis, the person behind Atlavium. An idea for your game, a bug or just a hello: I’d love to hear from you. Prefer email? You’ll find all contact options and help with common problems on the support page.
You can download your Realms as a ZIP with your notes, saved files and the connections between your entries. You get a notification when it is ready, then have seven days to download it. The format is open. Importing into Atlavium is not available yet.
A home for your Realm
Create your first Realm, add two characters and record what connects them. Your Atlavium can grow with your stories. Compendium features will remain free within your granted allowances.
