Behind the form is a six-step pipeline — research, outline, write, revise, fact-check, format. Each pass builds on the last, so the prose stays coherent across a 200-page book.

The EPUB lands in your inbox when it's ready — usually within an hour or two.

The reactor had been cold for seventeen years when Halden pushed the door open. It made a sound like something deciding whether to wake up. He understood, in the way a man understands rain, that heat had been leaving this building for longer than anyone had been paying attention — and that the leaving had a direction, and that the direction was the crime.

Entropy, his father had told him once, is not decay. It's just the way the universe keeps score.

He lit a cigarette and walked further in, counting the gauges that no longer moved…

A few knobs.
A book that
fits the brief.

Boundless isn't one template with a topic swapped in. Style, tone, length, and extras are independent dials. The output you get is shaped by every one of them.

The three styles cover most of what people actually want to read.

01

Three styles, not just fiction.

Narrative for memorable, story-driven learning. Textbook for structured rigor. Blend interleaves both — narrative chapters paired with expository ones.

3styles
02

Length is a real choice.

Quick (15k words) through Epic (80k). Or pick Optimized — Boundless researches the topic first and decides how long the book actually needs to be.

5length tiers
03

Tone, including yours.

Casual, academic, witty, inspirational — or describe a voice ("like Mary Roach", "like a 1940s noir narrator") and it writes in that register.

custom tones
04

Optional teaching scaffolding.

Add chapter summaries, a glossary, discussion questions, or real-world case studies. Toggle them in or leave them off — they count toward the page total.

4extras

Three briefs.
Three very
different books.

The same engine, three different shapes. Each one runs the full research → outline → write → revise → fact-check → format pipeline.

Narrative · Quick

A Field Guide to Compound Interest

TOPIC · personal finance · 15k words

A slow, generational story about a family vineyard. Interest compounds off-page. Readers finish understanding why rate and time matter more than timing.

Blend · Optimized

The Gardener of Small Machines

TOPIC · molecular biology · ~32k words

A cellular biologist disappears. Her niece pieces together her work — narrative chapters interleaved with expository deep-dives on DNA replication and protein folding.

Textbook · Deep Dive

Stellar Evolution: A Survey

TOPIC · astrophysics · 50k words

A structured monograph on stellar life cycles, with chapter summaries and a glossary toggled on. Designed for an undergrad reader who wants depth without a course.

People don't remember information. They remember stories — and the information that was hiding inside them.
