CLIFF Localization Suite โ A Complete Translation Workflow With Context and AI
Unreal stores text as a key, a source string and a translation. Nothing about what the string is โ a button, a noun, a line of dialogue โ survives into the tables your translators and your AI models read.
This plugin is the whole workflow around that gap: it puts the meaning back into every string, translates what is missing with AI, validates the result, and writes it into the engine's own localization pipeline. Extract, translate, review, ship โ from the editor, or from CI. The context format underneath is CLIFF (Contextual Localization Integrated Format) 1.0; this plugin is its Unreal side.

โจ WHAT YOU CAN DO
๐ Round trips that lose nothing
Import into the official manifest/archive pipeline and export back, with a key sidecar so your original namespaces and keys survive byte for byte.
๐งฉ A strict validator, not a text munger
Headers, groups, entries and the closed type/emotion/status vocabularies are validated in C++, matching the reference implementation. Errors come with file and line.
๐ค One-button AI translation
Export โ translate โ import in a single run. Only missing strings are translated, human-reviewed work is untouchable, placeholders are validated, and empty or unchanged results are rejected instead of written.
๐งญ Mapping you control
Three tables in Project Settings link semantic families to namespaces and derive type and tone. Nothing is hard-coded, and anything it cannot infer degrades to "sentence" with a warning instead of guessing silently.
๐งฑ Your pipeline, untouched
Custom GatherText steps, the official resource generator, the official progress window, Dashboard toolbar buttons. No engine patches, no Python, no third-party binaries.
๐ 15 languages included
The plugin's own interface ships translated โ zh-Hans, ja, ko, ar, ru and more โ with the native culture compiled too, so the editor never falls back to English.
