Keep your story world consistent, chapter one to the last

Worldbuilding tool for novelists and comic creators. Keep characters, settings, timelines, foreshadowing in one database, @mention them as you write, and let AI catch contradictions across your whole story. Not a ghostwriter — a story bible that checks itself.
Consistency over long fiction is a real problem, I run persona and world state systems for AI conversations in my product and the failure mode I know best is silent drift. A detail changes in chapter 12 and nobody notices until chapter 30. Does LitMemo flag contradictions on its own, or is it a reference you check by hand?

"Silent drift" is exactly the term — that chapter-12-to-30 gap is the whole reason it exists. Honest answer: today it's mostly on-demand, not a background watcher. @mentions keep entities tethered as you write, and when you run a consistency check the AI reads the relevant scope (the entity's facts + the chapters it appears in) and surfaces contradictions. There's some automatic flagging when you reference something that doesn't match your database, but it doesn't yet catch every drift the instant it happens.
Fully autonomous drift detection at scale is the hard part — context limits, cost, and false positives all fight you (you'd know that better than most). That's the direction I'm pushing, incrementally. Curious how you handle it on the conversation side — snapshot world state and diff, or run checks at turn boundaries?
The @mention system inside the actual manuscript is genuinely clever—most worldbuilding tools force you to context-switch between the doc and the database, but here the characters and timeline stay tethered to the prose as you write.

Thank you — honestly that context-switch is the whole reason this exists. I used to keep the manuscript in one window and a wiki in another, and I just… stopped updating the wiki. Tethering it to the prose means the database fills itself as you write, so it never goes stale.
The @mention feature is genuinely useful for keeping side characters straight across chapters, and the contradiction catch on my messy timeline saved me from a real continuity mess.

Side characters are exactly where it quietly earns its keep — you remember the leads, but the tavern owner from chapter 4 who's suddenly renamed in chapter 30 is the kind of thing that slips right past you. Really glad it caught the timeline issue before it turned into a real mess. Appreciate you running it on actual chapters, not just clicking around.
Hi Product Hunt 👋 I'm the maker of LitMemo.
I built it because long-form fiction breaks in a very specific way: 200k words in, a character's eye color flips, a magic rule contradicts chapter 3, and a foreshadowing thread you planted 50 chapters ago just… vanishes. Your readers remember your world better than you do.
LitMemo is a story bible that checks itself. Characters, settings, timelines, and foreshadowing live in one structured database — you @mention them as you write, and when you run a consistency check, the AI reads your entire work to surface contradictions (not a generic ChatGPT that knows nothing about your world). It's explicitly not an AI ghostwriter — the story is still yours.
It now goes beyond novels: you can lay out comic panels and generate art panel by panel, with characters staying consistent (on-model) across pages.
There's a free plan and a no-sign-up playground — no credit card, nothing to install. I'd love your honest feedback, especially from anyone writing something long. What breaks your worldbuilding? 🙏
