## Overview

Generate SEO-friendly URL slugs from titles in **any language** — powered by DeepSeek V4.1 Flash with **thinking disabled** for fast, direct output.

**Why AI instead of plain rules:** a rule-based slugger can only transliterate characters (在家煮咖啡 → `zai-jia-zhu-ka-fei`). This tool *translates the meaning* into concise English keywords (在家煮咖啡 → `brew-coffee-at-home`), drops stopwords like "the/of/and", and puts the highest-value search keywords first — the pattern recommended by Google's URL structure guidelines (hyphens, lowercase, short).

**How it works:**
- Your title goes to DeepSeek V4.1 Flash (`deepseek-flash`) in **non-thinking mode** (`thinking: {"type": "disabled"}`, the official parameter) — no reasoning tokens, direct answer, low latency and cost. When only an OpenRouter key is configured, the same generation runs as `deepseek/deepseek-flash-latest` with `reasoning: {"enabled": false}`.
- Every slug from the model is re-checked by a **deterministic sanitizer**: NFKD fold to ASCII, lowercase, single separators, whole-word truncation inside your character budget. A malformed model answer can never leak into your URL.
- You get one primary slug plus up to 4 alternatives, extracted keywords, detected language, and a one-line rationale.
- **Offline fallback:** if no API key is configured or the model call fails, the tool degrades gracefully to a rule engine (CJK → tone-less Pinyin via `pinyin-pro`, diacritics folded) and clearly marks the result as `degraded`. You can also force it with **Rules only (offline)**.

**Slug conventions applied:** lowercase ASCII, hyphen (or underscore) word separators, 3–5 words by default, ≤60 characters by default, stopwords removed, most important keyword first.

## Inputs

- **Title or Phrase** (textarea): Paste a title in any language, e.g. 在家煮出好咖啡的十个技巧…
- **Engine** (select)
- **Style** (select)
- **Separator** (select)
- **Max Words** (number): Upper bound on words in the slug
- **Character Budget** (number): Whole-word truncation limit (Google-friendly slugs stay under ~60)
- **Keywords to Include (optional)** (text): comma-separated, e.g. cold brew, recipe

## When to use

- When generating clean English permalinks from multilingual article or product titles.
- When standardizing website URL structures to comply with SEO character limits and lowercase hyphenation.
- When eliminating filler words and prioritizing high-value keywords in CMS slugs.

## How it works

- Enter a title in any language and configure your desired separator, style, maximum word count, and character budget.
- DeepSeek V4.1 Flash translates non-English meaning into direct English keywords in non-thinking mode for rapid processing.
- A deterministic sanitizer cleans the result with NFKD ASCII folding, removes stopwords, and truncates text cleanly at whole-word boundaries.
- Inspect the primary generated slug alongside alternative variations, extracted keywords, and language detection data.

## Use cases

- Multilingual Blog Localization: Translating non-English post headlines into clean English permalinks for international reach.
- E-Commerce Catalog URL Optimization: Shortening wordy product titles into compact, keyword-first slugs under 60 characters.
- Content Migration & Cleanups: Normalizing messy headlines containing punctuation, numbers, and special characters into standardized ASCII paths.

## Frequently asked questions

### How does the AI engine differ from the offline rules engine?

The AI engine translates semantic meaning into relevant English search keywords, whereas the offline rules engine performs character transliteration like Pinyin conversion.

### What happens if the AI service is unavailable?

The generator automatically falls back to an offline rule engine that folds diacritics and converts non-Latin scripts to plain ASCII.

### How does character truncation work?

Slugs are truncated strictly on whole-word boundaries so terms are never cut off in the middle of a word.

### Can I include specific target keywords in the slug?

Yes, specify comma-separated terms in the optional Keywords field to guide the generator toward prioritized keywords.

### Can I use underscores instead of hyphens?

Yes, select the underscore option in the Separator dropdown to change word separators from hyphens to underscores.
