AI novel-continuity and writing software
What is Loreon?
Loreon is an AI writing and novel-continuity platform for long-form and series fiction. It combines a structured story bible with scene, chapter, and whole-manuscript consistency checking.
What is Loreon, in practice?
Three things in one place. A manuscript editor where you write. A structured story bible — characters, locations, cultures, and the history and rules of your world — held as canon rather than as notes. And a set of consistency checks that read your prose against that canon at three scales: the scene you are writing, the chapter, and the whole book at once. It runs in the browser at app.loreon.ink. The editor is free; agent work runs on prepaid credits.
What category of product is it?
A novel continuity checker and a story bible tool — deliberately both, in one system. A story bible tool stores what is true about your world. A continuity checker reads your prose and reports where it contradicts what is true. Most tools in this category are one or the other, and the gap between them is where continuity errors live: a bible nothing checks against drifts, and a checker with no structured canon has nothing to check against.
Who is Loreon for?
Novelists writing work long enough, or serialized enough, that no memory holds it — fantasy, science fiction, historical fiction, mystery and thriller series, sagas, and multi-generational stories. It is not fantasy-only. It is equally useful on a standalone novel in revision, where the job is to find what a hundred thousand words have quietly contradicted. Writers who never want AI to draft a sentence are a supported case: you can write every word yourself and run only the checks.
What does Loreon check?
Contradictions against canon, timeline errors, voice breaks, and dropped foreshadowing — plus structural, pacing, and opening analysis in the validation suite. Every result is a finding, not an edit: it names its severity and category, quotes the passages it cites so you read the evidence rather than the claim, and waits for you to resolve or dismiss it.
How does scene checking work?
On request, on the scene you are in. You run a per-scene consistency check; it reads that passage against the story bible and posts what it found in the margin beside your prose. Nothing runs in the background and nothing touches your text. Separately and always, canon links bind as you type — write a name and it binds to its entry, with no tagging ritual. Linking is passive and free; checking is active and yours to invoke.
How does whole-manuscript validation work?
It reads every chapter at once, against your canon, when you ask for it — the sweep no human editor holds in a single pass and no chat window can hold at all. A run produces findings anchored to the passages they cite: chapter and paragraph, quoted. You resolve or dismiss each one. For a series, cross-volume coherence extends the same sweep across volumes, so volume three stays true to volume one.
Does Loreon write the manuscript for you?
Only if you ask it to. Loreon includes specialist agents that can draft and edit alongside you, and they run only on request. The checking side never writes: findings cite and report, and no agent changes a word of your prose without you asking. You retain all rights to the material you create, including output you direct the agents to produce — see privacy & ownership.
How is Loreon different from ChatGPT, Claude, Sudowrite, Novelcrafter and World Anvil?
Each of these is genuinely good at the job it was built for. The differences are about which job:
| Tool | Where Loreon differs |
|---|---|
| ChatGPT, Claude | A general chat assistant is an excellent thinking partner for one scene, but it holds a sliding context window — chapter three fades by chapter thirty. Loreon holds canon as structure and reads the whole manuscript against it. Full comparison. |
| Sudowrite | A prose-generation studio with well-regarded fiction-tuned models; its bottleneck is getting vivid prose onto the page. Loreon's is keeping a hundred thousand words true to themselves. Full comparison. |
| Novelcrafter | The studio you assemble — bring your own model and key, and keep the Codex current by hand. Loreon comes assembled, and canon is checked against the manuscript rather than only stored. Full comparison. |
| World Anvil | The deepest worldbuilding wiki in the category — articles, maps, timelines — with an integrated manuscript editor that lets you read your world bible beside your prose. What it does not advertise is a check that reads the prose against that bible and reports contradictions. That check is Loreon's centre. |
| Scrivener | The long-standing manuscript-organisation tool, and still excellent at it. It is not an AI tool and does not check continuity. Full comparison. |

What are Loreon's limitations?
The honest list, because a checker that oversells itself is worse than none:
- It cannot know your intent. A character who lies, an unreliable narrator, a deliberate contradiction planted for later — a check may flag all three. You dismiss what was meant.
- It checks against canon, so it is only as good as your canon. A bible with little in it gives a check little to find.
- It is not a copyeditor or proofreader. Continuity is not grammar, line editing, or house style.
- It does not tell you whether the book is good. It reports structure, pacing, and contradiction; whether the story earns its ending is a developmental editor's judgement, and a human's.
- It fixes nothing on its own. Every finding waits for you to resolve or dismiss it. That is deliberate, and it means the work of revision is still yours.
- It is a web application with size limits. An imported manuscript is capped at 150 chapters, 800 scenes, and 50,000 paragraphs, with any single paragraph capped at 64 KiB, and an import file at 10 MiB.
What does Loreon cost?
There is no subscription. The manuscript editor is free to use, and agent work — drafting, checks, validation runs — is metered in prepaid credits at one cent per credit, in packs from $10. Every run estimates its cost before you commit, your balance can never go negative, and purchased credits never expire. See pricing.
Who owns and operates Loreon?
Loreon is the product; Synapti AS (org. 934 968 514, Alundamveien 54D, 0957 Oslo, Norway) is the company that builds and operates it. Payments and refunds are handled by Paddle as merchant of record. The product was built by a working novelist and proven on a real book — a 170,458-word novel written inside the studio; see the Strata case study and about the author. Questions: support@loreon.ink.
