About
BookSparker is a web-based book marketing platform for indie and self-published authors. It brings audience-building and book-promotion tools together, including a genre- and list-size-matched newsletter swap marketplace, group promotions, reader-magnet and advance-review-copy delivery, sign-up landing pages, author websites, and universal links to booksellers. Authors can upload reader-magnet files for delivery in common ebook formats, collect subscribers, and connect supported email services such as MailerLite, Kit, and EmailOctopus. Free-plan features include limited monthly swaps, a landing page, email collection, and reader-magnet delivery. Paid plans add direct ebook sales through the author's Stripe account without a BookSparker commission. The platform is intended to help authors organize promotional activity and build relationships with readers.

About
OneKDP is a browser-based workspace for independent authors and self-publishers preparing books for Amazon Kindle Direct Publishing (KDP). It combines AI-assisted book and cover creation with editable interiors, a cover editor, KDP-oriented sizing and preflight tools, and separate exports for interior and cover files. It supports novels, nonfiction, workbooks, coloring and puzzle books, journals, and planners. Generated text and artwork can be revised before export. The service also provides publishing calculators and author tools for book details, descriptions, royalties, print costs, cover dimensions, and promotional copy. Manual tools and editing are available on a free plan; AI generation uses credits, while paid subscription plans add monthly credits and keyword research. Users review exported files and upload them through their own KDP accounts; OneKDP does not publish books automatically.
