An AI that learns how to read a specific book the way its author wants it read.

What this is
Not a writing tool

Kaizen R/W does not write for you. It does not lint your prose or enforce rules. It reads your manuscript the way an attentive editor would — noticing voice, rhythm, continuity, pacing, and intent — and quietly tells you what it sees.

A reading environment

The manuscript is the interface. No sidebars, no dashboards, no permanent chrome. You read. The AI highlights what it notices. You open a note, respond to it, and move on. The experience should feel like reading a book, not operating software.

An AI that learns your book

Every time you dismiss a note, teach the system why something is intentional, or flag a passage for later, the AI remembers. Over time, it stops treating your deliberate choices as errors and starts understanding what makes your book yours.

How it works
Load your manuscript

Paste text, upload a .txt, .md, or .docx file, or try the demo chapter. Multi-chapter manuscripts are detected automatically.

Read while it scans

The AI reads each chapter and marks 3–6 passages worth your attention — repetition, style, continuity, voice, pacing, interiority. Marks appear as subtle color shifts in the text. No icons, no highlights. Just warmth in the prose.

Notice, decide, teach, continue

Click any mark to see the AI’s reading. Press D to dismiss it. Press T to explain why it’s intentional. Press F to flag it for later. Every decision teaches the system. That’s the kaizen loop — small acts of attention, compounding.
