Draft, Edit, Format, and Market Your Book Without Paid Writing Software
TL;DR: Writing a book is hard enough without expensive software adding to the stress. Free tools for grammar checking, readability scoring, word counting, document conversion, PDF creation, social media promotion, and author website SEO handle the surrounding work that turns a manuscript into a published, discoverable book. I wrote and self-published two books using free tools for everything except the word processor.
My first book cost $340 in software before I typed a word. Grammar premium subscription, formatting tool, PDF converter, cover design app, and social media scheduler. All before selling a single copy. Twelve months of subscriptions before revenue.
My second book cost zero in software. Same quality editing. Same professional formatting. Same marketing reach. The only difference: I knew which free tools to use.
Writing and Editing
Grammar and Style
The Grammar Checker catches errors across chapters. The Readability Scorer analyzes reading level per chapter. Fiction should score 60-80 Flesch. Non-fiction varies by audience: general 55-70, academic 30-50.

Word Count and Progress
The Word Count tracks chapter lengths and daily progress. Consistent daily word counts finish books. The Word Density Counter spots overused words and phrases across your manuscript. The Word Cloud Generator visualizes which themes dominate each chapter.

FAQ
Can I format a book for publication with free tools? Free tools handle manuscript preparation (grammar, formatting, PDF creation). For final ebook formatting (EPUB, MOBI), you'll need Calibre (free open-source) or platform-specific formatters. For print interior layout, free tools like Reedsy or Atticus free tiers work.
How important is an author website? Very. It's the only platform you fully control. Social media algorithms change; your website doesn't. It's where mailing lists live, where blog content attracts new readers, and where search engines find your books.
Should I blog about my book before it's published? Yes. Blog about the topic (non-fiction) or the genre (fiction). Build an audience before launch. The content creator pipeline makes this efficient.
How do I mark advance review copies? Use the PDF Watermark tool. Stamp "ADVANCE REVIEW COPY - NOT FOR SALE" diagonally across every page. This is industry standard and prevents unauthorized sales.
