Flux Lang
A light multilingual layer for WordPress: Turkish by default, English at /en/, AI translation through Flux AI.
Flux Lang makes the site multilingual without a heavy plugin. Each post, page, project or event can have its own English (or German…) version with its own slug, image and SEO; menus and links follow the language, and the language switcher sits in the footer. Visitors from outside Turkey land on English right away, and Flux AI can translate a page in one click.

Flux Lang in action
The real plugin, real screens. A short tour.
Why Flux Lang?
Multilingual plugins tend to be the heaviest thing on a WordPress site: extra tables, rewrite rules, a string translation screen with thousands of rows. A charity with Turkish content and an international audience needs less:
-
English where it matters
Translate the pages that count; anything not yet translated still opens in Turkish under /en/ instead of a 404.
-
Links that follow the language
Menus, buttons and links in content point to the English version automatically, without touching the theme.
-
The right language first time
Visitors from abroad get English before the page is drawn; their choice in the switcher is remembered.
-
Translation in one click
With Flux AI the title, excerpt, SEO fields and body are translated piece by piece and opened in the editor for a check.
