The writing app for finishinga novel without losing your voice.
Extypis brings outline, narrative sheets, scene-by-scene drafting, revision and editorial AI into one workspace. You stay in charge of the voice, but you no longer carry the whole book alone.
Structure
A novel holds better when its architecture stays visible.
Outline, storyboard and scenes stay connected.
Simple structure, Save the Cat, hero circle, or a free outline. Reorder scenes without breaking the rest of the project.
A writing workshop built for novels that last.
A dense interface when you structure, silent when you write. Light or dark mode, shortcuts, fonts and typography all configurable.
From unstable idea to presentable manuscript.
Extypis supports a novel from the first idea to a presentable manuscript: structure, drafting, revision, then clean export.
Step 01
Catch the spark
A scene, an image, a line of dialogue. You capture the material before you fully understand it.
Step 02
Install the world
Characters, places, objects and themes stop being floating notes and become tracked narrative elements.
Step 03
Make the outline hold
The story takes a workable shape: acts, beats, scenes, chapter links and narrative health.
Step 04
Draft scene by scene
You move in the order that truly helps, with autosave, focus and recoverable versions.
Step 05
Use the AI when useful
Sidebar assistant, continuation, rewrite, pitch, narrative generation, cover: the AI steps in where it actually saves time.
Step 06
Revise before collapse
Repetition, passive voice, continuity and style issues surface before the long cleanup tunnel.
Step 07
Export a real manuscript
You export a clean, structured, reusable version of the book for whatever comes next.
Long-form fiction usually breaks on tracking, structure and fatigue, not just on “inspiration”.
Extypis is built to carry part of that operational burden too.
“I lose track of side characters.”
As the manuscript grows, details of presence, chronology and relationships leave your working memory.
The Extypis answer
Characters become sheets linked to the text through @mentions, with direct access from scenes and traceability across the project. And at worst, your quick notes — anchored to the text, accessible anywhere in one click — catch whatever doesn't have its place yet: a reflex so nothing slips through.
“My outline turns false as soon as the book moves.”
The moment a chapter moves, your side documents stop matching reality and your structure becomes decorative.
The Extypis answer
Narrative outline, storyboard and scenes stay linked at all times: moving a scene automatically updates its rank in the outline and its position in the storyboard. No side document to maintain by hand.
“Generic AI either helps little, or erases me.”
A broad tool sends back smooth, decontextualized prose that needs almost as much repair as help.
The Extypis answer
Extypis AI has constant, hands-off access to your outline, your character sheets and the scenes already written. No complex prompts to write: consistency with your novel is guaranteed on every rewrite, continuation, pitch or cover. The tool cannot give you an off-topic answer because it already knows your work.
“I write out of order, and my tool punishes me for it.”
When the ending scene burns before chapter three, overly linear tools break momentum instead of helping it.
The Extypis answer
Each scene stays movable, previewable and exportable in final order without forcing linear drafting.
“I stop seeing contradictions and stylistic tics after too many passes.”
The more familiar you become with the draft, the less you notice drift: repetition, passive voice, forgotten arcs, fragile chronology.
The Extypis answer
Analysis tools and AI continuity checks surface weak signals before they harden into manuscript problems.
“My final export never looks like the book I worked on.”
After months of writing, wasting time on a messy export feels like falling back to draft level again.
The Extypis answer
Extypis prepares title page, editorial sections and clean exports for sharing, printing or publishing.
Three value blocks instead of one blurry pile of features.
The fiction page should present the product as lived: a structure system, an editorial AI system, then an output system.
The book stays manageable while it keeps changing.
Extypis is strongest when a novel grows, shifts, sharpens and starts generating real internal dependencies.
Structured narrative plan
Beat-sheet structured around three reputable frameworks, with automatic narrative health and chapter mapping.
Storyboard
Story overview with summaries, labels, quick preview and scene reordering.
Non-linear writing
Write scenes in any order, then reorganize them freely.
@character mentions
Insert clickable mentions to your characters, locations and objects.
8 narrative element types
Dedicated cards for characters, locations, conflicts, themes, objects and more.
An AI that knows your whole novel, not just your paragraph.
On every generation, Extypis AI reads your outline, your character sheets and the scenes already written. Where a generic AI starts from scratch on every prompt, ours keeps the project coherent from chapter 1 to the final chapter.
AI writing assistant
Conversational AI assistant in the sidebar, color-coded quotes highlighted in the text and one-click rewriting from any passage.
AI rewriting in your text
Select any passage and let AI suggest a rewording right inside the editor.
AI continuation in your text
Type /continue and AI extends your text in your style.
AI nudge when you're stuck
When you pause, a discreet bubble offers an AI nudge. Press Tab to continue your sentence — never interrupted while you write.
AI continuity check
AI automatically detects contradictions, forgotten arcs and inconsistencies in your story, and saves the report.
AI presentation & summary
Tagline, short presentation and full summary automatically generated, saved and faithful to your story.
AI narrative element generator
Characters, places, events, themes… generated by AI with optional illustration.
Image generation (cover, places, characters)
Book cover + images of your characters, places, and objects, generated by AI. Free: 3 images, standard models. Premium: unlimited, pro editorial quality (Flux 1.1 Pro, DALL-E 3).
The project exits cleanly, without a ridiculous final week.
Finishing tools matter as much as drafting tools: versions, readability, front matter and exports should save time precisely when time is scarce.
Snapshots (versions)
Create versions, compare them and restore a previous state.
Readability score
Measure how easy or demanding your text is to read.
Repetition detection
Spot unwanted repetition and refine your style faster.
Passive voice detection
Spots passive voice sentences and highlights them. Shows the percentage of passive voice in the text. Useful for energizing your writing if you tend to overuse the passive.
Front matter and back matter
Preface, afterword, dedication, epigraph, table of contents (at the start or the end?): publishing has conventions no author really learns. Extypis guides you through every editorial fixture — title page, cover auto-cropped to book format, ISBN, copyright, opening and closing sections — and lets you reorder or hide any of them at export.
PDF export (LaTeX)
Generate polished PDFs with true typographic quality.
Multi-format export
Export to PDF, DOCX, EPUB, HTML, Markdown or full archive.
Everything Extypis unlocks for you
Five concrete capabilities: structure, write, (use AI 🤫), analyse, publish.
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.
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.
Daily writing comfort
Everything that makes long-form writing sustainable: shortcuts, templates, anchored notes, versions, goals.
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.
Structure and drafting start without friction. Paid plans mainly extend AI credits, advanced analysis and the depth of use once the project becomes demanding.
The questions novelists usually ask before stepping in.
Will Extypis AI write my novel for me?
No. It suggests, checks, rewrites, unblocks, helps present and helps revise. You keep final approval on the passages that matter.
Does Extypis AI really know my novel?
Yes. On every generation, it relies on your outline, your character sheets and the scenes already written. Where a generic AI starts from scratch on every prompt, Extypis keeps the full memory of your project so that suggestions stay coherent from chapter 1 to the final chapter.
Which AI features are actually available for fiction?
Sidebar writing assistant, targeted rewrite, inline continuation, contextual boost, narrative-element generation, continuity checking, project pitch, front matter and cover generation.
If I write out of order, does the tool still hold up?
Yes. Scenes stay independent, reorderable and previewable in the storyboard, then assemble cleanly at export time.
Is the AI the same for free and subscribed users?
No, and that goes for both text and image. On editorial-sensitive tasks (long rewrites, continuity check, editorial pitch, AI assistant), a subscription automatically switches the AI cascade to Claude Sonnet 4.6, the strongest model on French prose. Free users stay on Mistral, Llama, Cerebras and Gemini: very fast and excellent for drafting, more modest on finishing and long-form consistency. For image generation (book covers), free users get Flux schnell (fast, standard quality) while subscribers access Flux 1.1 Pro and DALL-E 3 (editorial quality, careful typography and better photorealistic rendering).
Are my projects used to train an AI?
No. Your texts are never sent to the models for training. None of the AI providers used by Extypis (Anthropic, OpenAI, Mistral, Groq, Gemini) has access to your content outside of the punctual API call required for the requested generation. The APIs are configured without training opt-in, and no data is retained on Extypis' side beyond what is strictly required to run the product.
Can I already export a clean manuscript without paying?
Yes to start seriously. Paid plans mainly extend AI usage, quotas and depth once the project becomes more demanding.
Is this only for fiction?
No, but the fiction page deliberately leans into novel-specific work: narrative planning, narrative elements, continuity, scenes, pitching and manuscript output.
Your novel deserves better than a bare editor and three side documents.
Start with structure, add AI where it genuinely helps, and keep the whole project inside a workspace that still holds once the book becomes large.
