02How it works

Five steps. Your team in the loop.

The agent drafts. Your team reviews and comments. The agent revises — and adds its own notes from having read the whole book. The output ships in the format your team already works with.

03When the source changes

Manuscripts change.
So do translations.

Editors revise. Authors send updates. Lexica tracks every manuscript version and re-runs only the affected units — the rest stays exactly as you approved it.

La tarde caía sobre los tejados de la ciudad vieja, y desde su ventana doña Inés veía pasar las nubes en grupos lentosen rebaños desperdigados, como rebaños regresando del campo. Pensó, sin tristeza, que ya había vivido más años de los que le quedaban. Pensó, sin tristeza ni vergüenza, que ya había vivido más años de los que le quedaban, y que aquellos pocos serían los suyos.

A single unit, translated live.

Pick a sample — or paste your own paragraph in any language. The agent will surface its glossary, then draft the translation in the voice it reads. This is one unit of the 247 your book will go through.
