Writing with AI is fast. Publishing isn't: Markdown breaks, asterisks stay visible, margins go off. Inkael takes your text and delivers it as a tidy, elegant, technically reliable book, without you becoming a designer or a technician.
Other editors show asterisks or strip the formatting. Inkael recognizes Markdown headings, bold and italics and turns them into real typography. Nothing to redo by hand.
No design decisions to make. A single, carefully crafted typographic system makes even a few pages read like a substantial book: the perception of value that low-density text usually lacks.
The same laid-out file, validated twice: PDF/X-1a:2003 for professional printing and PDF/A-1b for archiving, with correct color profiles and metadata. Files that are ready, not just promised.
A validated, accessible EPUB that passes EPUBCheck, ready for every ebook store. Check the live preview (e-reader, phone and print) before you even export.
Deliberately essential: usable right away, nothing to learn. And in every case, the AI's Markdown is honored.
Bold, italics and lists: the essentials, like an editor you already know.
Copy text from ChatGPT, Claude or Gemini and the Markdown instantly becomes typography.
Import your chapters as .txt files: the Markdown they contain is converted into real typography.
Native interface in 5 languages and an independent export language: work in one language and publish in another. Your text stays as it is. It's the editorial framework that adapts, on its own, to each country's standard.
Tap a card to read the table of contents and copyright page.
Paste the text from AI (ChatGPT, Claude, Gemini) or import a .txt file. Reorder the chapters with a drag.
Check the book live: e-reader, phone and print. Choose the size (5×8, 5.5×8.5, 6×9).
Generate a validated EPUB and a print-ready PDF, ready for Amazon KDP, IngramSpark and other stores.
