Five passes, then ship.
A studio pace. Each stage agreed before the next.
The manuscript.
We read end to end, audit the document styles, write a one-page brief covering chapter starts, drop caps and footnotes.
The structure.
Semantic markup — sections, parts, chapters, asides — given epub:type. Navigation and landmarks built.
The typography.
Widows, orphans, drop caps, ornament breaks — refined so the book reads well at every font size a reader chooses.
The size-pass.
Tested at small, medium and large type on Kindle, Apple, Kobo and Thorium. Anything that breaks is rewritten.
The handover.
Validated EPUB, source documents, stylesheet, screenshot pack and notes file. Everything you'd need to update later.

What we stand behind.
Each promise written into the proposal.
If any storefront rejects the file, we re-cut at our cost and chase ingestion support until the title clears.
EPUB package, stylesheet, working source, screenshot pack — yours at sign-off, no lock-in.
Every file ships with a passing EPUB 3.3 report. Tested at three font sizes on four reading apps before it leaves the desk.
Typos, metadata edits, late ISBN, accessibility tags — fixed at no charge for the first month after the file goes live.
How to start a reflowable eBook project with ebookwriting.ai.
Four short steps from manuscript to clean, store-ready file.
- Send the manuscript. Email a Word or Google Docs file with chapter headings and any inline images. We confirm receipt within one working day.
- Receive a fixed-price proposal. Within 48 hours, you get a written quote (typically $180 to $520 depending on length), a timeline, and a one-page contract.
- Approve the proof. We send the EPUB, the KPF twin and a screenshot pack across three font sizes in 5 to 9 working days. One revision round is built in.
- Upload to your storefronts. We hand over every package — KDP, Apple, Kobo, Google Play — plus the validation reports, or upload on your behalf if you grant account access.
More about our reflowable EPUB work.
Our reflowable EPUB formatting is the default for any text-led book — fiction, memoir, business, self-help — where the reader will adjust font size, line spacing and brightness on their own device. We work with authors, hybrid publishers and ghostwriting clients who want a file that behaves well across Kindle, Kobo, Apple Books and library systems. Most jobs ship in four to six working days.
What makes a good adjustable text EPUB
A reflowable file is good when it disappears. The reader scales the type, swaps to night mode, picks a serif or sans, and the book responds without breaking layout. Adjustable text EPUB work depends on relative units — em and percent rather than pixels — and on letting the reader's device handle typography rather than fighting it. We strip the fixed-pixel CSS most converters leave behind.
Font-scaling EPUB behaviour matters more than most authors realise. If a reader bumps the type two sizes up to read on a phone, a fragile file will collapse table layouts, drop drop-caps onto the wrong line, or strand a chapter heading at the bottom of a screen. We test every file at the smallest and largest font sizes on a real Kindle, Kobo and iPhone before delivery.
Accessibility-first screen reader EPUB work
An accessibility-first ebook is built so a screen reader EPUB experience is as good as a sighted one. That means correct heading hierarchy, alt text on every meaningful image, a navigable table of contents, declared language, and no decorative content masquerading as semantic. Most clients ask for this because a school, library or institution requires it — but it's how we build every reflowable file regardless.
Deliverables: a validated, epubcheck-clean EPUB 3, a KPF for Amazon if you want it, and a one-page note flagging the small differences each platform will render. Source XHTML is included.
Questions we are asked.
Short, honest answers. Anything else, send to contact@ebookwriting.ai.
What does the starting figure include?
At ebookwriting.ai, the starting reflowable eBook fee of $180 covers a single manuscript formatted as a reflowable EPUB 3, semantic structure, navigation, accessibility tagging, image handling, and one revision round after your proof.
How long does the build take?
Five to seven working days for prose, slightly longer for books with footnotes, tables, or heavy image content. The schedule is written into your proposal once we've seen the final manuscript.
What if the text reflows oddly on a specific device?
Reflowable EPUBs respond to user font size and screen width, so some variation is expected. We test on the major reading apps before delivery and include a revision round for anything that genuinely breaks the read.
Who owns the files?
You do. The validated EPUB, the source documents, and a short notes file are handed to you at the end so you control all future updates.
What is delivered?
A validated reflowable EPUB 3, a PDF proof, screenshots from the main reading apps, and the editable source. We include a short style note so future formatters understand any non-obvious decisions.
When should I choose reflowable over fixed-layout?
Reflowable is right for prose, business, memoir, and most non-fiction — anywhere the reader expects to adjust text size and night mode. Fixed-layout suits picture books, comics, cookbooks, and anything where the spread itself is the design. If you're unsure, we'll recommend the right format in the proposal.
