Fastest Way to Write a Book with AI in 2026: SidekickWriter vs. The World
If you’ve ever stared at a blank page for three hours only to end up with a single sentence about the weather, you know the struggle. Writing a book is hard. Writing a good book is even harder. But in 2026, the barrier between "I have an idea" and "I have a manuscript" has finally collapsed.
The question is no longer if you should use AI, but which tool is actually the fastest way to write a book without losing your creative soul in the process. While many generic AI writers offer "push-button" books that read like they were written by a very polite toaster, a new generation of tools is focusing on the "co-pilot" experience.
In this comprehensive guide, we compare the top contenders—SidekickWriter, Sudowrite, Novelcrafter, and Jasper—to see which one truly offers the fastest path to a finished, high-quality book.
In this guide you will learn
- Why a structured workflow is faster than a "chat" interface.
- How SidekickWriter’s 7-step process finishes novels in under 2 hours.
- A detailed feature comparison across the major AI writing platforms.
- The importance of "continuity" in long-form storytelling.
- Why free writing tools are the best way to start your journey.
1. The Core Difference: Workflow vs. Prompting
The biggest mistake new AI writers make is treating AI like a magic genie. They open ChatGPT, type "Write me a 50,000-word thriller about a detective who is also a cat," and are disappointed when they get a 500-word summary that makes no sense.
The "Generic" Approach (Jasper/ChatGPT)
Generic AI tools are built for short-form content: blog posts, emails, and social media. They lack "narrative memory." By the time you get to Chapter 5, the AI has forgotten what happened in Chapter 1. This means you spend more time correcting the AI than actually writing.
The "Specialized" Approach (SidekickWriter/Sudowrite)
Specialized book tools understand structure. They break the book down into an outline, characters, and scenes. This is the fastest way to write a book because the AI isn't just guessing—it's following a blueprint you designed.

- Collaboration: Use public share links and the integrated feedback system to get beta reader notes directly inside the app.
4. What The Competitors Are Best At
Sudowrite
Sudowrite is the "artistic" sibling. It excels at "Show, Don't Tell" and sensory descriptions. It’s fantastic for fiction writers who want to dive deep into specific scenes and rewrite them in different "flavors." However, it lacks the structured, end-to-end workflow that makes SidekickWriter so fast for non-fiction and academic work.
Novelcrafter
Novelcrafter is for the "planners." It is a powerhouse for organizing your personal "Codex" (world-building notes). It’s highly technical and offers great control over which AI models you use. The downside? It has a steep learning curve that can actually slow you down if you just want to get the words on the page.
Jasper
Jasper is the king of marketing. If you need to write a sales page for your book or 50 different Facebook ads, Jasper is unbeatable. But for writing a 300-page manuscript? Its lack of long-form structure and character continuity makes it a frustrating choice for authors.
5. The SidekickWriter 7-Step Fast-Track Workflow
The "Fast way to write a BOOK" isn't about typing faster; it's about following a proven system. SidekickWriter automates the boring parts of this system:
- The Spark: Use the "Random Idea" generator or refine your rough concept.
- The Voice: Select a genre-specific style (Fiction, Business, Academic) or define your own.

- The Blueprint: Generate a full chapter-by-chapter outline in seconds.
- The Detail: AI suggests chapter descriptions to ensure plot points are hit.
- The Birth: Watch the book stream in real-time. Stop and adjust whenever you want.
- The Exit: Export to professional DOCX or EPUB formats, ready for Kindle or a publisher.
6. Frequently Asked Questions
What is the fastest way to write a book with AI?
The fastest way is using a "Completion-Focused" tool like SidekickWriter. By breaking the process into a structured 7-step workflow (Idea -> Outline -> Generation), you avoid the "lost in the woods" feeling of generic AI chats. Most users finish a full draft in 1-2 hours.
Is AI-written content eligible for copyright?
In many jurisdictions, including the US, works entirely generated by AI without human intervention cannot be copyrighted. However, SidekickWriter is designed as a co-pilot. You provide the ideas, the characters, and the outline, and you edit the final output. This "human-in-the-loop" approach is the standard for modern authors.
Can I write a non-fiction book with citations?
Yes! SidekickWriter includes a dedicated Research Engine that searches real academic databases and the live web. It can format citations in APA, MLA, Chicago, and more, making it the premier choice for researchers and business experts.
Does SidekickWriter support fiction and non-fiction?
Absolutely. SidekickWriter uses a system called "PromptFactory" that changes the AI's behavior based on your genre. Fiction mode focuses on narrative and character arcs, while Non-Fiction/Academic mode focuses on logic, facts, and structure.
