umContentTranslator
Translate Umbraco pages and dictionaries with Claude or OpenAI, keeping block structure
Umbraco 17–18 package that translates content trees and dictionary items with Claude or OpenAI, keeps Block Grid and Block List intact and tracks status.
dotnet add package umContentTranslator
The problem it solves
Multilingual Umbraco sites need every page copied into each language and kept in sync when the source changes. Doing it by hand, or through tools that do not understand Block Grid JSON and rich text, is slow and often breaks the layout. umContentTranslator sends only the translatable values to an AI provider and writes the results back into the right culture.
Typical uses
- Launching a new language version of an existing Umbraco site
- Keeping translations current after the source page changes
- Translating dictionary items for a multilingual front end
- Translating meta titles and descriptions for international SEO

What umContentTranslator does
Choose the AI provider, model, reasoning effort and token limits in the backoffice, and override them for a single job.
Nested Block List, Block Grid and single-block editors are walked field by field, so layout and settings are not touched.
Rich text, Markdown, multiple textstrings, multi-URL picker and plain strings each have their own handler, so links and markup survive.
Umbraco dictionary items can be translated alongside page content.
When SeoToolkit MetaFields is installed, meta title and meta description are translated in the same job.
A Translation Logs view shows jobs, warnings and errors per node, and flags pages that need translation, need an editor check or are out of date.
Mark fields to keep unchanged and add custom translation instructions for tone or terms.
Jobs run one at a time on the server, with Pending, Running and Finished status shown live.
