All Features: Translate WordPress with AI

Everything included in every Lang Forge plan.

Updated June 2026

Lang Forge is a complete WordPress translation plugin. Below is every feature, grouped by what it helps you do. Use the anchors on the right (or scroll) to jump to the section you care about — and every feature links to a dedicated page with deeper detail.


Core translation features

AI translation — the reason you’re here

Lang Forge is an AI-first WordPress translation plugin. Every translation you’d otherwise do by hand can be done by AI in one click, across every kind of content WordPress supports.

  • Three modes: per-segment (click one paragraph), bulk (translate an entire post), background (translate hundreds of posts via WP Cron)
  • Powered by GPT-4o and DeepLrouted through our managed backend, so you never paste an API key anywhere
  • Cost estimation before you hit “go” on bulk jobs so you know what a site-wide translation will cost in credits
  • Glossary-awareterms you marked “do not translate” are respected automatically
  • Quality check after every AI translation with a 0–100 score on missed sentences, tone drift, and grammar, plus a “Fix” button for every flagged issue

Visual translation editor — translate on the live page

Two editors, pick whichever fits the job.

  • Split-screen editor (original left, translation right) with verified core support for Elementor Free widgets, ACF/Field Forge repeaters and flexible content, Gutenberg blocks, and WYSIWYG fields; Elementor Pro and third-party widget packs should be checked on the target site
  • Frontend visual editor with a click-to-translate toolbar that appears on your live site — click any text, edit the translation in a popup, save without reloading
  • AI Translate All button inside both editors — translates every remaining segment in one request
  • Glossary validation — highlights spots where the current translation violates your terminology rules

Translation memory — never translate the same text twice

Every translation you produce, manually or with AI, is saved in Lang Forge’s translation memory. The next time you translate a similar sentence, it’s there as a suggestion.

  • SHA256 exact matching for identical strings
  • 75% fuzzy matching for near-identical strings
  • Auto-fills suggestions in the visual editor
  • In-memory cache so loading a translated page doesn’t trigger extra SQL queries

Glossary — keep your terminology consistent

  • Term dictionary with “do not translate” flags for brand names and product names
  • Automatically applied during AI translation
  • Validation pass in the visual editor flags violations
  • CSV import and export for agency and translator workflows

Full glossary feature →


Content and post-type features

One-click site duplication for new languages

Spin up an entire new language version of your site with one click. All posts, pages, custom post types, categories, tags, and media are duplicated. Optional: run AI translation in the background immediately after.

  • Cost estimation up front (how many credits will this take?)
  • Background processing through WP Cron so the admin doesn’t time out
  • Full progress UI

Content diff — GitHub-style change tracking

When you update the original post, the translated versions can become outdated. Lang Forge shows a word-level visual diff — green for additions, red for deletions — so your translators know exactly what changed. A “Mark as current” button confirms the translation is up to date.

Full content diff feature →

Auto comment translation

Visitor comments are auto-translated to the language of the reader’s current page view. Cached in comment_meta so translations happen once, not on every pageview.

Translation analytics

Dashboard view of per-language translation progress, top translators, event log, and stats by post type.

Full analytics feature →


WooCommerce and e-commerce

WooCommerce multilingual

A first-class feature, not a half-documented integration.

  • Product titles, short and long descriptions, attributes, variations, categories, tags
  • Cart, checkout, and order-received pages in the core WooCommerce flow
  • Order-language tracking and core WooCommerce email strings; custom email builders and extension emails need QA
  • Currency formatting and date formatting per language
  • Price sync across language versions so you don’t maintain multiple product lists

Full WooCommerce feature →


SEO features

Automatic hreflang and XML sitemap

  • Custom /sitemap-hreflang.xml listing every language version of every indexable post
  • Also injected into the native WordPress sitemap (WordPress 5.5+)
  • Fallback for query-based URL structures
  • Auto-ping to Google when the sitemap updates

Full hreflang + sitemap feature →

SEO plugin integration

Translated meta titles, descriptions, canonicals, focus keywords, and Open Graph tags are copied automatically when a post is translated. Supports Yoast SEO, Rank Math, All in One SEO, SEOPress, and The SEO Framework.

4 URL formats

  • Directorysite.com/en/page/
  • Parametersite.com/page/?lang=en
  • Subdomainen.site.com/page/
  • Domain mappingsite.co.uk/page/

Visual radio card picker in settings — no arcane configuration.

Full URL formats feature →

Language switcher

  • 3 styles: dropdown, list, or flag selector
  • Widget, shortcode, and menu item
  • Admin bar switcher that only shows languages with existing translations
  • Works with any theme, no template edits required

Full language switcher feature →


String translation and theme text

String translation

Register and translate every UI string in your theme and plugins — button labels, form placeholders, menu items, widget titles. Auto-scan theme files for translatable strings. Standard __() and _e() calls from allowed domains are auto-registered via gettext on page render.

  • AI Translate All button for bulk translation of strings
  • Batch INSERT IGNORE at shutdown so page loads stay fast
  • Per-string “needs update” flag when the source changes

Full string translation feature →

Professional translation workflows

XLIFF and CSV export / import

Export translatable content as XLIFF 1.2 (the standard format for professional translation agencies) or as CSV for in-house workflows. Import translated files back with a single click.

Full XLIFF feature →

Translator role

A WordPress role with limited permissions (translate, not publish). Email notifications to translators when new content needs attention.

Professional-grade features at plugin price

Translation memory, XLIFF, content diff, and analytics are the same features agencies pay thousands of dollars per seat for in enterprise TMS software. In Lang Forge they’re included in every paid plan — and the glossary is free for everyone.


Developer features

REST API — 12 endpoints

Headless WordPress support out of the box. Endpoints for languages, translations, strings, translation memory, glossary, and admin operations.

Full REST API feature →

WP-CLI — 11 commands

Command-line control for automated workflows, CI/CD pipelines, and agency site setup.

  • wp langforge status — translation status by language and post type
  • wp langforge translate — translate a post by ID
  • wp langforge export / import — XLIFF / CSV
  • wp langforge tm-populate — seed translation memory from existing translations
  • …and 6 more

Full WP-CLI feature →

WPML compatibility layer

icl_get_languages(), icl_object_id(), icl_get_current_language(), icl_get_default_language(), and the icl_language_selector action are all implemented. Theme code written for WPML keeps working after migration.


Performance

Designed not to slow your site down

Lang Forge uses a preload_translations() batch method on the the_posts hook to eliminate N+1 SQL queries on multilingual frontends. Translation lookups hit an in-memory cache, not the database. String auto-registration happens in a single batch INSERT IGNORE at shutdown, not per-string on every pageview.

Most multilingual plugins noticeably increase page load times. We built Lang Forge to avoid that.

No API keys.

You don't manage OpenAI or DeepL credentials. We handle the provider relationship, the rate limits, and the token accounting. You just click "AI Translate" and watch it work.

Per-segment, bulk, and background modes.

Translate a single paragraph, an entire post, or every published article on your site in one pass. Long jobs run in the background via WP Cron so your admin screen never freezes.

Quality check on every AI translation.

After the AI finishes, a second pass scores the result 0–100 on missed sentences, tone drift, and grammar. You get fix buttons for every issue, not just a "try again" button.

Translation memory that learns.

Every string you translate manually or with AI is stored in Lang Forge's translation memory with SHA256 exact-match and 75% fuzzy matching. The next time a similar sentence comes up, you get an instant suggestion and save on AI costs.

Glossary with "do not translate" flags.

Lock your brand names, product names, and technical terms so AI never mangles them. CSV import/export for agency workflows.

Every Feature. Every Plan.

No upsells, no gated add-ons. Lang Forge includes everything starting at $54/yr.
