AtelierMonde
Session prep, minus the bookkeeping

A continuity editor for your campaign.

For game masters whose world has outgrown their notes: it flags the name that changed and the faction that flipped, before the next session.

You still write every scene, every NPC, every twist.

Before you write it down Session prep
King's eyes: written grey three sessions ago, about to be green tonight — flagged.
NPC name: one syllable off from an ally already in your notes — flagged.
Harbor faction leader: changed eight sessions ago — confirmed, no conflict.
Treaty terms: signed twice in your notes, with different wording — flagged.

How it works

  • 1

    Bring in what you've got

    Your existing notes as they are, in your own words, or a blank page for a new campaign.

  • 2

    Keep writing your way

    Whatever ruleset, notebook or wiki you run: no new system to learn, no session slowed down to feed it.

  • 3

    Get flagged before the table

    Contradictions surface in the quiet minutes before a session, never during it. Your attention belongs to your players.

What it keeps straight

  • Names

    Characters that drift

    An NPC one syllable off from an ally, a king whose eyes were grey three sessions ago: flagged.

  • Timeline

    Events in order

    The tavern keeper who died two sessions ago doesn't walk back into tonight's scene unnoticed.

  • Factions

    Who sides with whom

    The faction that changed hands eight sessions ago is surfaced before you have to remember it.

  • Plain text

    Your notes stay yours

    Exportable anytime, in the same plain text you wrote them in.

r/worldbuilding alone counts more than 1.9 million members swapping notes on their own fictional worlds.

One plan, the price on the table

Your notes stay yours; this watches for what stops adding up.

Is this just another AI generator?

No. It doesn't write your world for you. You write it, in your own words; it watches for what stops adding up, the way a second pair of eyes would.

Will my players see any of this?

What you mark as hidden stays hidden from players by default. Sharing is something you choose, not something that happens automatically.

What will it miss?

It catches contradictions in what you've actually written down; it won't guess at details you never noted. Your unwritten lore stays yours to keep straight.
