Fastest Way to Write a Book with AI: SidekickWriter vs Sudowrite vs Novelcrafter in 2026

Writing a book used to take years. Then, with the first wave of AI, it took months. In 2026, the question has changed from "Can AI help me write?" to "What is the fastest way to write a book with AI without sacrificing quality?"

If you are staring at a blank page, you don't just need a chatbot; you need a completion-focused workflow. Today, we are comparing the titans of the AI writing world—Sudowrite, Novelcrafter, NovelAI, and the new speed king, SidekickWriter—to help you find the fast way to write a BOOK that actually sells.

In this guide you will learn

1. Why SidekickWriter is the current speed champion for book completion.
2. How Sudowrite and Novelcrafter compare for creative fiction.
3. The key features that differentiate a "chat assistant" from a "book generator."
4. A detailed comparison table of features, including citations and collaboration.
5. A 7-step workflow to finish your first draft in under 2 hours.

1. The Core Difference: Speed vs. Assistance

SidekickWriter: The "Sidekick" Philosophy

SidekickWriter is built for one thing: Completion. It doesn't just help you write; it drives the project from a rough idea to a 50,000-word manuscript in a single session. By using a structured 7-step workflow (Idea → Style → Characters → Outline → Chapter Descriptions → Generation), it removes the decision fatigue that slows down most authors. It is the fastest way to write a book with AI because it treats the AI as a co-pilot, not just a thesaurus.

Sudowrite: The Fiction Partner

Sudowrite is the darling of the fiction world. Its philosophy is built around sensory details and expanding your prose. It is excellent for "unsticking" a writer who has a scene in mind but can't find the right words. However, because it requires manual intervention for almost every paragraph, it is significantly slower than SidekickWriter for finishing a whole book.

Novelcrafter: The Series Architect

Novelcrafter is for the "plotters." It uses a complex "Codex" system to track every detail of your world. If you are writing a 10-book epic fantasy series, Novelcrafter is unbeatable for consistency. But for the average author looking for a fast way to write a BOOK, the setup time for the Codex can be a major speed bump.

2. Feature Comparison Table

When you need to move fast, you need specific tools. Here is how the major competitors stack up against SidekickWriter in 2026.

3. What SidekickWriter Is Best At

SidekickWriter shines when you want to finish. While other tools focus on the process of writing, SidekickWriter focuses on the product. It is uniquely powerful for:

• Non-Fiction & Academic Writing: It is the only tool in this list with a built-in research engine that fetches real web data and formats APA/MLA citations automatically.

A simple way to think about it:
