Tomevell

Local AI book studio

A working publishing house, on your own machine.

Tomevell plans, researches, writes, fact-checks, edits and binds complete books — fiction and nonfiction — using local AI models. Nothing leaves your desk unless you say so.

Where books begin

Three doors into the studio. Write one sentence yourself. Let the trend scout bring you a subject the world is already moving toward. Or let another machine commission the whole thing while you sleep.

A handwritten index card whose sentence dissolves into flying typeset letters
Plate I·a — You. One sentence is enough; the interview does the rest.
A paper globe with violet threads feeding a book
Plate I·b — The scout. World signals, filtered for shelf life, not headlines.
A pneumatic capsule delivering a book commission slip
Plate I·c — Your agents. One API call: subject, length, budget. Done.

The one rule everything follows

Tomevell decides what work must be done.
The model router decides which model does each piece.

The manufactory

A book is not one long prompt. It is a hundred small, checkable jobs: a thesis, an outline, research questions, evidence sorted to sections, drafts, transitions, critiques, rewrites, a binding pass. Tomevell runs them as a durable pipeline — every step recorded, every step resumable.

Thirty seconds, the whole journey:

Plate II — Commission to bound book. Drafting room, research library, writing hall, editing desk, bindery.
Paper-craft cutaway of the book factory
Plate II·b — The floor plan. Chapters travel left to right; nothing skips a room.
III

The safeguards

Long books fail in quiet ways: characters knowing things they haven't learned yet, state that resets between chapters, claims that sound right but aren't sourced. Tomevell treats all of them as engineering problems, not hopes — and its repair engine can take an already-finished book back through the same discipline, chapter by chapter.

A violet ruler blocking a sentence from entering chapter three
Plate III·a — The leak fence. A secret scheduled for chapter nine cannot appear in chapter three; deterministic code, not model judgment. 22 leaks caught in the last novel.
A card catalog drawer with a claim card linked to three sources
Plate III·b — The claims ledger. Every factual statement carries an id, its sources, and a verdict: supported, weak, or contradicted.
A state ledger between scenes

Who is alive, what broke, what cannot un-happen — folded forward into every next scene. Contradictions are flagged by code, not hoped away.

Two critics before the door

Every finished book is read whole by independent critics and scored on the shelf. Below the bar, the weakest chapters go back to the desk.

Nothing is overwritten

Every draft, rewrite and edit is a kept revision. The whole book has a history you can walk.

Crash-proof by test

The acceptance test kills the process mid-sentence. The book resumes exactly where it died — and never pays twice.

A report per book

Which model wrote what, every token, every second, every catch — the full provenance, kept.

IV

The casting office

No model is hired on reputation. Before a book is written, candidates audition blind — same brief, hidden names — and are scored against each other. The best writer for this book gets the chair. Sometimes the small model wins; in our last audition, it did.

A paper switchboard routing roles to different typewriters
Plate IV·a — The router. Architect, writer, researcher, critic, editor — each role patched to the model that earns it.
Six masked typewriters on a small paper stage before judges
Plate IV·b — The audition. Six candidates, masked. Judges never score their own kin.
V

Yours alone

Tomevell runs on your hardware against local models. A book can be produced with the network switched off — and a local-only setting makes that a promise, not a preference: the manuscript never leaves the machine. Cloud models are an option you grant per book, never a dependency.

A manuscript in a wooden cabinet sealed with a violet wax stamp
Plate V — The cabinet. Sealed by default. You hold the only key.
VI

Off the press

The end of the pipeline is not a text file. It is a book: front matter, chapters, sources and notes, bound to EPUB, DOCX and PDF with checksums and the exact toolchain recorded — ready for a store, an editor, or your shelf.

Three finished books beside an e-reader and a stack of printed pages
Plate VI — One manuscript, three bindings. Same words, wherever they need to live.
VII

For machines like yours

Everything a person can do in the studio, an agent can do through the API — REST, MCP, or the command line. Your automation commissions a book, polls its progress, approves its gates, and collects the files. It never needs to know which models did the work. That decision belongs to the house.

Plate VII — Four doors, one house. A slip goes in; a book comes out.
VIII

The scout

Not every headline deserves a book. The scout watches world signals and climbs a strict ladder — news, event, trend, structural change — keeping only subjects with years of shelf life. What survives arrives as a worked-out proposal: subject, reader, angles, and a recommendation.

Plate VIII — The world, spun to threads. Only the long ones reach the desk.

The shelf is waiting.

Tomevell is in private development. If you want early access — as an author, a publisher, or someone whose agents should be writing books — say hello.
