Lay your book out the way a publisher would: real typesetting, chapter openers, running heads, and a cover built to the exact trim size you sell at. Pick a theme once and every page follows it. The file you download is the file you hand to the printer.

Non-fiction chapters are built on material found on the web right now — real studies, articles, figures and quotes — instead of only what the model happens to remember. Every claim comes back with the source it came from, so you can check it, keep it or swap it. Write about something that changed last month and the book already knows about it.

All books currently appear in a single grid regardless of whether they belong to a series or are standalones. Adding folders, tags, or shelves would allow grouping books by series and keeping standalones organized separately.

I would like a Google Docs-style version history for each chapter, so that I can switch between previous revisions and avoid losing my content if I make a mistake or an AI generation fails.

Quote and teaser graphics are pulled from your actual manuscript in Instagram post, Story, Pinterest and Facebook sizes, each one arriving with the caption that goes with it, plus hooks and shot lists for TikTok and Reels and 3D mockups of the book. A launch needs thirty of these at the very least, and closer to sixty or ninety if you want to rotate them without repeating yourself. They arrive as a batch in a suggested posting order, instead of one graphic a night in Canva.

Having separate author profiles for different pen names would help when writing across multiple genres. Supporting up to 5 pen names per account would allow writers to keep the associated details distinct as they branch out into new genres.

See rank, reviews and sales for every book you have published in one place. Each book comes with one specific suggested fix — a weak blurb, a wrong category, a missing keyword. You spend your time on the book that actually needs it.

Allowing authors to specify word count ranges for chapters or sections helps control pacing, estimate effort and costs, and meet editorial standards. Setting target lengths during planning reduces revisions and ensures the content matches length guidelines.

Character portrait cards help with marketing and can be used as a book cover maker when added to a character page. Having a tool to generate them would help show off characters and their stories.

When exporting a manuscript to DOCX format, the cover image is automatically included. External editing tools like AutoCrit can run into errors importing documents containing images, requiring manual deletion of the image before import. Adding an option or checkbox to exclude the cover image during DOCX export would streamline this workflow.

Checking consistency while writing currently requires copying each chapter into an external document, because the application does not allow any export before the book is complete. Being able to discuss and analyze the content produced so far would allow revising and correcting issues without waiting for the end of the manuscript.

Allow creating a named series and adding books to it once. Currently, creating a new book in a series requires re-importing every previous book or selecting them individually from the full library, then manually re-editing characters and locations, which risks inconsistencies across the series.

Allowing authors to upload real or synthetic voice samples would help maintain personal authenticity across audiobooks. It would also enable multi-character voice recordings for fiction, allow quick audiobook updates after manuscript edits, and let an author's distinct voice narrate books in multiple foreign languages.

It is essential to have strong security features to protect accounts and information. The platform should offer two-factor authentication (2FA) that does not rely on email as an option for all accounts.

Convert children's books, teen books, adult books, and e-books into flipbook-style videos that can be uploaded and watched on YouTube and social media.

I would like to make manual text edits directly in the Book Editor without having to select the text and invoke the AI each time.

Every image comes out at the size and under the rules the platform actually enforces: BookBub's 300x250 static frame with your cover filling about half of it, Amazon Sponsored Brands headlines inside the 50-character limit with no price or savings claims, Sponsored Products inside 150, and Meta sets in both 1:1 and 4:5. Get any of that wrong and the ad is rejected, or it runs and quietly wastes the spend. You get several variants per book, so you can test which one earns the click instead of running one image and hoping.

Add an optional button to automatically generate an image for a chapter so there is no need to write a prompt manually.

Moving the editor to the step directly before the publishing section within Book Flow would make the entire writing and publishing process much more streamlined.

Uploaded or generated images currently get placed at the end of the chapter with left, right, or center alignment. They should instead be insertable directly at the cursor with text wrapping around them, which would make direct exports usable without needing to edit the document in Word first. Support for image captions is also needed, which is important for non-fiction books and for adding required labels to AI-generated images. Finally, a central image library would allow an image created in one project to be reused in another book.

Allow visual resources and authoring tools to use the active book's context directly—such as pulling in its title, author, and text elements automatically—instead of requiring us to re-enter details manually.

Add an option to use a custom OpenAI-compatible API key as a bring-your-own-key (BYOK) provider.

Ideas generated on a free account are appearing under previously created ideas on a separate paid account linked to a different email. Book planning and brainstormed ideas should remain private to each individual user account.

Add the ability to delete uploaded files inside the editor when they become redundant, and add folder support to better organize uploaded files.

Include a dark mode because it is easier on the eyes, and many creators and writers prefer high-contrast colors and less visual strain. Additionally, when using a tablet or laptop, dark mode helps reduce battery consumption.

Please add an option to switch the application interface to a dark theme.

It would be helpful to chat directly with the AI about uploaded reference material and past chapters. When writing a long series, it is easy to forget earlier details or notes, so having a dedicated chat tab to query uploaded resources or ask for feedback on a specific chapter would save time.

A built-in recording setup with a scrolling teleprompter would help authors record their own audiobooks directly in the app. Basic editing tools to stop, start, clip out mistakes, and balance audio levels across sessions would make it easy to get started, with the option to expand capability via Web Audio plugins.

Allow more control over manga and comic layouts, including typesetting and font formatting. A blank canvas where creators can visually customize their layout, choose the number of panels, and arrange them—similar to how Anifusion works—would give much more flexibility.

Add a search magnifying glass or find feature directly on the chapter editing page so writers can quickly locate a specific passage in their text.

Adding voice-to-text input directly to text boxes would make it easier to capture details while ideas are fresh.

Many technical books include mathematical equations. Providing an option to export books in LaTeX, at least using the standard book document class, would make typesetting and formatting those equations much easier.

On the My Books page, show the date each book was created, and add a checkmark or confirmation step to prevent accidentally deleting a book.
