Fantasy, dark fantasy, romantasy — the workshop that holds the worldbuilding.
Sanderson-grade magic system consistency, living glossary, maps and timelines wired into the text, editorial AI that knows your world, export ready for Tor, Orbit, DAW or Gollancz. The fantasy writing software that remembers what you forget by page 600.
Structure
Hero's Journey, Three-Act or Sanderson-style narrative plan pre-loaded, or free outline for the pure storytellers.
A fantasy saga turns on its scaffolding — not on a brilliant chapter 3 idea.
The twelve stages of Campbell's Hero's Journey, three-act structure, or a free outline depending on your method. You adapt to genre codes — high fantasy, sword & sorcery, progression fantasy, cosy fantasy, grimdark — without being forced into any pattern.
From the first scribbled map to the bookstore shelf.
Catch the spark of the world, lay the laws of magic, build your peoples and characters, write the quest, hold consistency over 800 pages, ship a manuscript ready to go.
Fantasy sagas don't die for lack of world.
They die because the author can't find the detail set in chapter 12, and no longer dares move forward.
Three promises, atop a stack of features.
Hold the worldbuilding over time, support a saga without it contradicting itself, ship a manuscript ready to go — publisher, platform or contest.
The world holds as the manuscript grows.
Peoples, Kingdoms, Magic, Creatures, Religions, Locations, Objects, Conflicts sheets — all wired to the text via @mention. One source of truth, from prologue to book 5.
An AI that reads your world, not a fantasy dictionary.
The AI knows your peoples, your magic laws, your characters. It continues, rewrites, checks consistency — never invents a dragon you didn't establish.
From finished manuscript to bookstore — no patch-up job.
Publisher-spec DOCX (Tor, Orbit, DAW), EPUB for contests and beta, book-quality PDF for self-publishing, chapter-by-chapter HTML for Royal Road.
Give your project a real reading address.
Once the text is ready, you don't have to leave Extypis to find your first readers. Publish in one click on the public catalog and give your book a clean, readable, shareable page.
Published directly on Extypis — no fees, no middleman.
Publishing opens a dedicated page for your project: cover, title page, chapters, table of contents. The content is frozen at publication, so your readers always see a stable version while you keep working. You decide when to push a new version.
A reading page for each project
Customizable URL, title page, cover, table of contents and chapter-by-chapter navigation.
A catalog that helps readers find your book
Your project can appear in the public catalog, categories, subcategories and trending page — or stay accessible only through the direct link.
Readers who can actually react
Readers can comment chapter by chapter, mention a specific paragraph, and you get notified for every feedback.
A stable version without breaking your work
The text is frozen at publication time. You keep writing on your side, then decide when to push an update.
Everything Extypis unlocks for you
Hold your story, from outline to final page.
Narrative tools you won't find elsewhere — turn a tangle of ideas into a structure that holds.
AI that suggests, never replaces
The AI permanently sees your whole project — outline, sheets, scenes already written. Every rewrite, every completion, every suggestion, every cover stays consistent with your entire work, and at no extra cost or setup. You approve every word.
Estimates if you only use this feature. Credits are shared across every AI tool.
Daily writing comfort
Everything that makes long-form writing sustainable: shortcuts, templates, anchored notes, versions, goals.
Ship a book, not a file.
From manuscript to finished book: professional exports, academic citations, direct publishing.
Analyse and refine your prose
Style tools that go beyond the spell-checker: readability, poetic meter, repetitions, connectors, passive voice.
Lifetime updates
Every future Extypis innovation included, no extra cost, no paywall.
Backing an indie project
Extypis is an independent, self-funded project — no ads, no venture capital.
Human support
Got a question? You talk directly to the creator, never a chatbot.
Free to begin, even to finish. Serious when you need to go deeper.
The work of worldbuilding and writing is entirely yours. The subscription gives you a thoughtful co-pilot, an occasional co-author, and an objective reader drawn from your target audience.
Frequent questions, plain answers (still friendly).
Does Extypis work for a saga with a complex magic system ?
Yes — it's precisely one of our strongest use cases. You create a dedicated Magic sheet where you set your rules (cost, limit, source, price paid — Sanderson's Three Laws fit in five lines). That sheet is one click away from the text, and the AI reads it before each continuation. The narrative consistency check flags any scene that violates an established rule. Whether you're writing hard magic à la Sanderson or soft magic à la Tolkien, consistency holds.
How does Extypis handle a multi-volume cycle ?
Each book is a project, but you can create linked projects. All narrative sheets (peoples, kingdoms, magic, characters, events) can be viewed and exported across projects. The cumulative timeline lets you verify no event in book 2 contradicts book 1's chronology. And the automatic glossary catches your 80+ proper names to prevent spelling drift between volumes.
Does Extypis work for romantasy (fantasy + romance) ?
Yes — it's a major use case. Combine the Romance narrative plan for emotional beats with the dedicated narrative elements system for worldbuilding (magic, creatures, kingdoms). Peoples, Kingdoms, Magic sheets handle the fantasy depth; the Gwen Hayes beats handle the relationship. Both threads live in the same project, linked by @mention — exactly the dual narrative regime authors like Sarah J. Maas or Rebecca Yarros work in.
Can I build a constructed language (conlang) in Extypis ?
Yes, to the level a fantasy author actually needs to maintain. You create a dedicated sheet for your invented language (lexicon, pronunciation rules, examples) consultable at every scene. The automatic glossary catches your terms to prevent spelling drift. For very advanced conlanging (full phonology, generative grammar à la Quenya), a dedicated tool like PolyGlot stays more relevant — but Extypis comfortably holds the level of linguistic invention found in published sagas at Tor or Orbit.
Can I export for Royal Road or contest submissions ?
Yes — multi-format export covers both tracks. For Royal Road or Wattpad: chapter-by-chapter HTML, formatting preserved (italics, bold, line breaks) — direct copy-paste. For publisher submissions (Tor, Orbit, DAW, Gollancz, Angry Robot, Saga Press): industry-standard 12pt DOCX, double-spaced, title page. For contests (Hugo, Nebula, World Fantasy Award): EPUB or PDF to spec.
Is the AI going to write my fantasy for me ?
No. Extypis's AI proposes, never replaces. It continues a sentence, rewrites a passage, flags a worldbuilding inconsistency, suggests three variants — you validate each word, or refuse. And if you write entirely without AI, the app remains fully functional; AI tools are an option, not a requirement. For authors like Brandon Sanderson, Robin Hobb or Joe Abercrombie, voice is the central instrument — Extypis stands behind it.
What does Extypis cost to start ?
Free, no credit card. 50 AI credits offered for life + a generous daily cap. The subscription extends AI usage and analysis depth when your project becomes more demanding — typically once you write more than 1,500 words a day or manage a multi-volume cycle in parallel.
What does « Extypis » mean ?
« Ex typis » is a Latin formula that appeared on the frontispieces of printed books from the 16th to 18th centuries, right before the printer's name — literally « from the presses of… ». The word derives from the Greek τύπος (typos): imprint, model, mark left behind. That's exactly the lineage we claim: a digital workshop that prepares your manuscripts in the great European typographic tradition, until they're worthy of being printed.
I built the writing app I'd always wished for.
Having finished a novel after several attempts, and built up years of poetry — kept right here, on Extypis — I saw firsthand how many writing blocks are really method problems, easy to move past once you give yourself the right tools. Technique doesn't replace imagination — it carries it. If you're writing a fantasy saga seriously, Extypis is for you too.
