iLang Readable Slugs: A WordPress Plugin That Finally Fixes Percent-Encoded URLs for Non-Latin Content

Where This Fits Before You Install It

If you run a WordPress site in Chinese, Japanese, Korean, Arabic, Russian, Thai, or any other non-Latin script, you already know the problem this plugin solves: WordPress takes your post title and either leaves it as-is (rendering an unreadable string of percent-encoded characters like %e4%bd%a0%e5%a5%bd%e4%b8%96%e7%95%8c in the URL bar) or you manually retype a slug in English every single time you publish. Neither is sustainable past about the tenth post.

Here's the important distinction: Yoast SEO, Rank Math, and All in One SEO do not solve this. They're general-purpose SEO suites — meta descriptions, schema markup, readability scores, sitemaps, redirect managers. Slug editing in all three is still a manual text field. None of them translate or condense a non-Latin title into a clean English slug for you. If your workflow is "write title in Japanese, get an English slug automatically," those three tools simply don't have that feature, at any price tier.

iLang Readable Slugs is a single-purpose plugin that does exactly one thing: on save, it sends your post title to an AI model (via an OpenAI-compatible API) and gets back a short, readable, hyphenated English slug — then applies it to the post. That's the whole product. It's not trying to replace your SEO plugin; it's meant to run alongside Yoast or Rank Math, handling the one job they don't.

Who Should Actually Pick This Over Just Using Rank Math or Yoast

• You publish in a non-Latin script and are tired of either garbled URLs or manually transliterating every title
• You've been hand-typing pinyin, romaji, or transliterated slugs and want to stop
• You want slugs that read naturally to English-speaking visitors and search engines, not literal transliterations (e.g., a slug like beginners-guide-to-soy-sauce instead of chushoku-no-tsukurikata or a percent-encoded mess)
• You already use Yoast/Rank Math/AIOSEO for the rest of your SEO stack and just need slug generation bolted on

If your site is already in English, this plugin has nothing for you — go use Rank Math's built-in slug field like normal.

What It Actually Does

On publish or update, the plugin reads the post title, sends it to a configured AI endpoint (SiliconFlow is the default provider, but any OpenAI-compatible API works — including OpenAI itself if you supply your own key), and receives back a condensed, hyphen-separated, lowercase English slug. It then sets that as the post's permalink slug, same as if you'd typed it into the slug field yourself. There's no dashboard, no analytics layer, no content scoring — it's a background utility that fires once per post save.

Pricing: Free Plugin, Pay the API Directly

The plugin itself costs nothing — it's hosted on wordpress.org like any free plugin. But it doesn't do the AI work itself; it calls out to an external API, and that's where the real cost lives:

• Plugin license: $0, always
• Default provider (SiliconFlow): free signup credits, which for typical blogging volume (a handful of posts per day) tend to last a long time — research suggests years for normal use
• Per-slug cost: each generation runs roughly 100 tokens, which comes out to a fraction of a cent per post
• Bring-your-own-key option: you can point it at OpenAI or another OpenAI-compatible endpoint if you prefer, at whatever that provider charges per token

There's no subscription tier, no "pro version," no upsell inside the plugin. Your only real recurring cost is API usage, and at 100 tokens a slug, even a site publishing 500 posts a year is looking at a cost measured in single-digit dollars, not a line item you need to budget for.

Concrete Use Cases

• A Japanese cooking blog publishing daily recipes gets slugs like miso-soup-with-tofu instead of %e5%91%b3%e5%99%8c%e6%b1%81 or a manually-typed misoshiru-no-tsukurikata
• An Arabic news aggregator running WordPress multisite generates readable English slugs for every regional edition without a human touching the permalink field
• A Korean beauty product review site monetizing through affiliate links gets slugs like hyaluronic-acid-serum-review that are actually shareable on Western social platforms, instead of encoded gibberish that breaks when pasted into Slack or Twitter
• A Russian technical blog cross-posting to an English-speaking dev audience via RSS wants URLs that don't look broken in the feed reader

Setup Reality Check

You need an API key before this plugin does anything. That means signing up with SiliconFlow (or another OpenAI-compatible provider) and pasting the key into the plugin's settings page. It's a five-minute step, but it's not zero-config — if you were hoping for something that works the second you activate it with no external account, this isn't that. It's closer to how Akismet needs an API key, not like a typical set-and-forget formatting plugin.

The Honest Verdict

This isn't a Yoast or Rank Math competitor — it's a niche fix for a problem those tools were never built to solve. If you're running a non-Latin-script WordPress site and have been either living with ugly URLs or manually typing slugs for every post, this plugin removes that chore for effectively no cost. If your site is in English, or if you were hoping for a full SEO suite, this isn't it and was never trying to be. Install it alongside whatever SEO plugin you already use, spend five minutes getting an API key, and stop thinking about slugs.
