One world, many books
Characters, settings, timelines, and foreshadowing shared across books. The sequel never starts from scratch, and never contradicts the previous book.
Get started nowLitMemo lets the books in one world share characters, settings, timelines, and foreshadowing, so a new sequel finds the whole set of material already there, no rebuilding from scratch. The most painful part of writing a sequel is forgetting the previous book's side-character names and settings and spending half a day flipping through old drafts — world sharing pulls up the full settings with one click. And when the same character has a different status in different volumes (alive in this book, gone in the next), that's no problem: per-volume overrides let each volume be edited independently without contaminating the others. That's the biggest difference from copying your worldbuilding into several versions scattered across books.
"What was that side character in the last book called again? What were their settings?"
Writing the sequel, every detail of the previous book's characters rests on memory. Looking it up takes half a day; not looking it up risks getting it wrong. One universe's worldbuilding scattered across different files — a vicious cycle.
The core features of Cross-book sharing — one world, many books sharing characters and settings
Cross-book material sharing
Characters, worldbuilding, timelines, and foreshadowing all live at the world level for central management, and when you open a new book, all this shared material is already there — no copy-pasting, no rebuilding piece by piece. A world is the container holding many books, all of them sharing the same underlying material. For authors writing trilogies and dozen-volume runs, this means every character and setting accumulated in the previous book is a ready-made asset, and the sequel starts on the shoulders of the previous book — rather than rebuilding the whole universe with every volume, which is both laborious and a breeding ground for cross-book contradictions.
- Character cards shared across books
- Worldbuilding shared across books
- Timeline events shared across books
Per-volume override mechanism
Shared is shared, but the same character's status often differs from volume to volume — alive in book one, gone in book two, or a setting that changes in the sequel. Per-volume override is designed for exactly this: you can override a character's status or a setting entry within one particular book, and that change takes effect only in that volume, without affecting the same character in other volumes at all. This solves the thorniest dilemma of cross-book sharing — needing to share one base set of material while allowing each volume its own plot differences — and in LitMemo the two can coexist without clashing.
- Independently override a character's status
- Independently override setting entries
- Overrides don't affect other volumes
World overview
The world workspace lets you survey the whole universe from one place: every book's characters, settings, and chapter summaries presented together, plus a relationship graph linking the entire world, so the whole universe lies in full view. Do you still remember every side character from book one by the time you're on book five? By memory, impossible. The world overview is your map of the universe — reviewing a cross-book thread, confirming which volumes a character appeared in, seeing how the whole world's relationships evolved, all without switching back and forth between several books, the whole picture in one view.
- World workspace for unified management
- Cross-book chapter summaries
- World-wide relationship graph
Have you run into this too?
「Writing book three, and you've forgotten every side-character name and setting from the first two」
Characters and worldbuilding all live at the world level and are shared across books, so when you open book three as a new book in the same world, the material from the first two is already there — full settings a click away. No flipping back through two old books to gather up the characters one by one, and no writing the sequel's side characters out of step with the earlier volumes.
「The same character is alive in book one but dead in book two, and the settings clash」
Per-volume override lets one character card record a different status in each volume — mark them dead in book two, and the living version in book one is entirely unaffected. Sharing one character base while each volume keeps its own plot differences — both can hold true here at once.
「A trilogy's worldbuilding spread across three books, where one change means syncing three times」
Keep the worldbuilding at the world level for central management, and a shared setting changed once syncs across the whole world — no more opening three books to edit three times and maybe missing one. When one volume genuinely needs a local difference, a per-volume override handles just that one spot.
The usual way vs LitMemo
| The usual way | LitMemo | |
|---|---|---|
| Cross-book material | Rebuild for each volume | World sharing inherits automatically |
| Previous book's settings | Flip through old drafts to recall | Full settings a click away |
| Cross-book character status | Change it, clash everywhere | Per-volume override, independent per volume |
| Worldbuilding sync | Copy manually into several versions | Change once, sync across the whole world |
| Grasping the whole | Scattered across books | World workspace at a glance |

Frequently asked questions
A world is the container holding many books. Characters, settings, timelines, and foreshadowing that live at the world level sync automatically to every book inside it, and when you add a sequel, all this shared material is already there — no copy-pasting, no rebuilding piece by piece. The sequel starts on top of every character and setting the previous book accumulated, rather than rebuilding the whole universe with each new volume.
LitMemo's per-volume override mechanism is designed for exactly this. A shared character's status can be independently overridden in each book (say, alive in book one, dead in book two), and that change takes effect only in that volume, without affecting the same character in other volumes at all. It shares one character base while allowing each volume its own plot differences — the two can coexist without clashing.
It depends on your plan (see the pricing page). Whether it's a trilogy or a dozen-volume run, every book in the same world shares the same set of characters, settings, and timelines. The world workspace lets you survey the whole universe from one place — every book's characters, settings, and chapter summaries presented together, plus a relationship graph linking the entire world — so even on book five you needn't fear forgetting book one's cast.
Yes. Every book lives in a world, and the characters, settings, and timeline that book accumulated already sit at the world level — open the sequel as a new book in the same world and they're there from the first page, no copying, no rebuilding. You don't have to tear down and rebuild an old book just to share its settings.
