An AI-Powered Writing Studio

Where Stories Find
Their Structure

No5Writer combines expert editorial coaching with genre-specific structural frameworks — giving your story the guidance it deserves from first draft to final page.

Named after the Underwood No. 5 — the first “visible writing” machine.

The Craft

Everything a novelist needs

AI Editorial Team

Five expert AI personas guide your writing at every stage — from acquiring editor to beta reader, each bringing a unique professional perspective.

Genre Frameworks

Purpose-built structural templates for mystery, thriller, romance, literary fiction, fantasy, and sci-fi — grounded in how published novels actually work.

Writing Studio

A three-panel workspace: your outline on the left, manuscript in the center, AI coaching on the right. Everything visible. Nothing hidden.

Each AI persona brings a distinct editorial lens to your work — the same perspectives that shape novels at traditional publishing houses.

Copy Editor

Refines prose at the sentence level — voice, rhythm, word choice, clarity

AI Coach

Dev. Editor

Strong opening image. Consider grounding Eleanor's emotional state before the letter arrives…
