Translating a whole deck and being able to prove it arrived intact is what separates a delivery from a promise. The document changes language; the layout, the notes and the formatting stay where they were, and the receipt shows, item by item, what changed and what stayed.
One language goes in, another comes out
Four formats, each with its own unit preserved, and the proof attached
The presentation comes back with its slides, text boxes and speaker notes in place; the document, with its sections; the spreadsheet, with its sheets, without touching the formulas; the PDF, with the text redrawn on the page and everything else identical, byte for byte. The text changes language; everything else stays. And the proof of that is not a sentence from us: it is a comparison that arrives with the file and that you can reopen whenever you want.
And today's state, dated. Translation has been down since 2026-08-23 over provider credit, and the last successful run was on 2026-08-20 at 22:43 UTC. This page describes the capability and does not invite a live test until that returns.
Differentials
The receipt, the vault and the glossary are what comes back with the file
Any tool hands you back a file in another language. What decides the purchase is what comes back with it: the item-by-item receipt, born from the operation itself and therefore unable to disagree with it; your translated version entering your vault as a whole document next to the original, not as an attachment; and your glossary applying from the first slide to the last.
All three, and why the boundary where the model’s text enters your file is checked instead of assumed, are in differentials.
Languages
The offer states what it withdraws, and an absence is not a refusal
When a destination drops out of the offer you see, it drops out with the reason attached. That looks like an interface detail and is a product decision: an absence is the only answer that cannot carry a reason, and you deserve to know whether your language was refused or simply never measured.
Which destinations you get, which are withdrawn, why Arabic works in a presentation and not in a PDF, and why a language nobody has measured yet can still be offered to you, are in languages.
Layout preserved
The structure stays because the engine has no permission to touch it
Your layout survives by a boundary, not by effort: the engine changes content inside the structure you already built, and it does not create, delete, duplicate or reorder slides, sections or pages.
What that guarantees, what changes in the PDF, and where the guarantee ends (that is the visual check, and it stays yours), are in layout preserved.
What translation hands back enters the vault as material: that is where the next one starts, create the next document out of what you already have.
