Your translations. Your workspace.
Edit, assign, review and release multilingual catalogs. Keep the project on your computer and exchange review packages without an online platform.

JSON: nested objects with string leaves. ARB: messages plus original metadata. Original files are never overwritten.
Choose a target language and a string.
Import a translation
Create an empty language
Update the original
Existing approvals remain tied to their exact source text. Changed strings return to review automatically.
Catalogs in this project
Translation memory
Only currently approved translations are added. Suggestions are drafts until you review and approve them.
Terminology
Advanced QA rules
Pseudolocalization
Create an expanded, accented test catalog with protected variables. This is synthetic test content, not a translation or an automatic screenshot test.
Send work for review
Export unapproved strings. The reviewer opens the package in this same HTML application, edits it and returns a response file. No account is required.
Receive completed work
Compare the original package, the response and the current project. Conflicts require an explicit choice. Returned translations always require your approval.
Previous delivery / baseline
Run checks to inspect structural errors, terminology warnings and review status.
A release requires every current source string to be approved and no structural errors. Terminology warnings remain visible for human review. Draft catalogs can be saved from the editor.
Project history
Last 200 events. Restoring a translation creates a new draft. Source updates are preserved in complete project backups.
Edits remain drafts. The project owner resolves conflicts and approves translations after importing your response.
