Built to be trusted

Accessible book production is usually slow, manual, and easy to get wrong — content gets re-keyed, structure gets lost, and the steps are scattered across tools that don't talk to each other. ADT Studio brings the whole process into one place, around three non-negotiable ideas.

One book, one folderEvery book lives in a single, shareable directory — zip it, move it, hand it off.
Nothing overwrittenEntities are versioned, never replaced. You can always roll back to an earlier result.
Cached & inspectableEvery LLM call is cached and openable. Change the inputs and only the changed work reruns.

Transparency by default

Every prompt, every response, and every cost is something you can open and read. When a result looks wrong, you can see exactly which call produced it, change the inputs, and rerun — only the work that actually changed is recomputed.
