Early access. Aethercircuits launching first.

Your characters, remembered forever.

Kosmonode tracks characters, campaigns, and shared worlds for any tabletop RPG, and passes the legacy on. The graph underneath does the remembering.

No spam. We only email when there's something to play with.

How it works ↓Pricing

One platform for every game you'll ever play

Three ideas the rest of the product builds around.

System-agnostic
D&D, 40K, Aethercircuits, your own homebrew. One platform. System packs handle the rules. The graph underneath stays shared.
Event-sourced
Nothing is overwritten. Every level-up, battle, alliance, and death gets recorded as an event with its causes and consequences attached. The history is the product.
Built to outlive you
Characters become memorials. Stories pass to heirs. Worlds keep going across generations of players. Kosmonode is the only TTRPG tool that plans for a 40-year window.

From character creation to legacy

Four steps. The rest is whatever your table makes of it.

  1. 01
    Pick a system

    Install a system pack. Aethercircuits at launch, with more on the way. Creators can ship their own.

  2. 02
    Build a world

    Characters, factions, regions, items. Every entity is a node. Every relationship is an edge.

  3. 03
    Play and record

    During the session, log events as they happen. Battles, levels, alliances, deaths, all captured live.

  4. 04
    See the story

    Timeline. Causal chains. Memorial views. Your world told back to you with the threads still attached.

Legacy

Some characters are too good to lose to a notebook.

Right now, the story your friend told as a wizard, the feat your dad pulled off as a barbarian, every campaign that mattered, all of it lives in someone's head. Until it doesn't.

Kosmonode lets you memorialize a character, hand heirs read access to their full history, and publish their story so other people can see what they did and who they were. A tombstone for the lives that lived inside the dice.
