For the campaign that's gotten too big to remember

Movies have a continuity editor. Your campaign deserves one too.

You still write every scene, every NPC, every twist. This helps you catch the name that changed, the faction that flipped sides, the eye color from three sessions ago — before your next session.

r/worldbuilding alone counts 1.9M+ members (Reddit, 2026) — people swapping notes on their own fictional worlds. None of the tools built for them actively check whether a world still adds up.

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.

Preview — illustrative

You've had this world in your head for months. It's starting to slip.

Your campaign started in a notebook, moved to a wiki, then a spreadsheet, then back to loose notes. None of them ever fully replaced the others.

A tavern keeper who died two sessions ago and just walked back into tonight's scene. A treaty your notes signed twice, with different terms.

You've spent evenings reopening old notes just to check one detail. And other evenings not checking, hoping nobody at the table remembers better than you do.

Prep itself has quietly become a second job you don't get paid for.

Not because building the world isn't the fun part. It's because so much of the time goes to bookkeeping instead of the twist you actually wanted to write.

And this time, you've got a second pair of eyes

On a film set, someone's only job is noticing that the glass moved between takes. Not writing the scene, not acting it — just making sure nothing contradicts itself.

Your world accumulates the same kind of detail over dozens of sessions, with nobody playing that role for it.

The name that's about to come out wrong gets flagged before your next session. The faction that changed hands eight sessions ago gets surfaced before you have to remember it yourself.

You still write every word — it just doesn't all have to live in your head alone.

Next to the story you're already telling

It works in the ten-minute gaps before a session, not during it — your attention at the table belongs to your players.

It doesn't ask you to switch systems or learn a new app. It sits next to whatever you already run — whatever ruleset, whatever notebook or wiki you've built your habits around.

It just replaces what you did instead — reopening a hundred pages to check a detail, or hoping it holds.

There's no new ritual to maintain, no session slowed down to feed it: the way you prep and run your table stays the same.

How it works

1. Bring in what you've got.

Your existing notes, as they are — or start from a blank page if you're beginning a new campaign.

2. Keep writing, your way.

Every scene, every NPC, every twist stays yours, in your own voice.

3. Get caught quietly, before it shows.

The name that changed, the faction that flipped — flagged before it reaches the table.

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.

Do I have to rebuild my world from scratch?

No — bring in what you've already written, and it starts watching from there. You keep creating new material the same way you already do.

What happens to my notes?

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

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.
