EpigraphIA doesn't include AI models, and doesn't charge for usage. Connect one, two, or all the APIs you prefer — use the ones you already pay for, and if you don't use one, simply don't connect it. You pay each provider directly only for what you consume. Zero markup, zero subscription fees, zero middlemen.
Writes the prompts, expands ideas, builds worlds and polishes prose. His pen runs on the text models you connect.
Turns prompts into illustrations, character portraits, covers and vectors. His chisel runs on the image models you connect.
The illustrations of Xolo and Beaver you see above were generated with EpigraphIA's own Image Studio — using Gemini. If you like them, you'll be able to create yours the same way.
Seven reasons indie creators choose EpigraphIA as their main editorial studio — and stay with it.
Connect your own API keys. EpigraphIA never acts as a middleman. You pay providers directly, with no markup. Total control over which models you use and when.
One purchase, free updates. No monthly subscriptions, no hidden fees, zero surprises on your statement.
Your projects, images and manuscripts live on your hard drive. No uploads to the cloud, no daily login required to use the app. See the privacy section below for details.
Every export meets Amazon KDP specifications. Trim sizes, spine width, bleed, margins and DPI — all automatic, no surprises when uploading.
Share projects, templates, fonts and palettes across modules. What you create in one is available in all the others — no exporting, no re-importing.
Clean, accessible interface. No steep learning curves. Intuitive from day one — whether you're coming from a design app or publishing your first book.
Everything you create with EpigraphIA is yours and can be sold. Publish it on Amazon KDP, sell it in your own store, use it for client work — no permission needed. The app is built precisely for that.
They share templates, fonts, palettes and projects. What you create in one appears in the others — no exporting, no re-importing, no consistency drift. All orchestrated from Home, on a single screen.
The editorial studio starts here. Home is EpigraphIA's operations center: a clean, fast and friendly interface that orchestrates more than 10 modules to create, illustrate, lay out and publish books on Amazon KDP — all from a single screen. No jumping between apps, no reopening files, no hours lost juggling tabs or syncing versions.
What takes five windows, eight logins and two subscriptions in other apps fits on a single screen here.
Generate dozens or hundreds of consistent illustrations in minutes. Define audience, theme, style and quantity. Xolo writes optimized prompts in batch and Beaver turns them into images with the model you choose (Gemini Nano Banana, FLUX, gpt-image-1). Everything vectorized locally with Potrace.
Producing 50 coloring pages used to take 2 weeks. With Sketcher: one afternoon.
A drag-and-drop visual editor built for KDP. Page by page, two-page spread view. Drag text, images, shapes. Integrated Pixabay library. Automatic full-wrap cover calculation. Pre-approved templates for children's books, journals and planners.
Generic design apps don't understand KDP. Pro layout tools have a brutal learning curve. Book Studio gives you the best of both.
Write novels, short stories, non-fiction. Editor with chapters and scenes. Builder for worlds (places, magic systems, laws) and characters with portraits generated by Beaver. Xolo works as an assistant with literary skills: helps you review your manuscripts, provides literary-contest-style verdicts, offers style suggestions and much more.
The best of visual card apps, knowledge management and AI-assisted writing — in a single app, with Xolo and your AI.
Hero covers, character portraits, unique high-resolution illustrations. Unified access to the best image models — Gemini Nano Banana, FLUX, gpt-image-1 — without jumping between apps. Beaver optimizes the prompt; you pick the model. Fast variations and inpainting when the model supports it, so you iterate until you nail the perfect version.
