The first plugin that writes AND links with semantic AI.
One core and six modules working together: AI writing, semantic linking by embeddings, knowledge bases, image generation, translation and automation. All inside WordPress, with no copy-pasting between tools.
Internal linking like no one else does it.
Three layers working together: explicit rules you control, semantic AI that discovers relationships, and a triangular pattern that keeps Google from penalizing your site.
You define the logic.
Set explicit rules: which keyword links to which page, with what anchor text, at what priority. Pillar pages receive preferred links from across the site.
- Rules with priority and frequency per rule
- Literal, variable or random anchor text
- Pillar pages, exclusions and link map
The AI discovers relationships.
Each post becomes a 1536-dimension vector. The plugin compares vectors to find relevant links that keywords can't detect.
- Score 0–1 with configurable threshold (default 0.65)
- Detects orphan posts automatically
- Works in any language without training
The pattern that protects you.
Instead of reciprocal links (A↔B), we create triangular cycles A→B→C→A. It distributes authority more naturally and avoids patterns that Google penalizes.
- No penalizable reciprocity between pages
- SEO authority spread organically
- Effortless: the plugin builds the cycles
Generate content that doesn't smell like AI.
AI produces recognizable text: filler, overused connectors, made-up data. 4Linking adds 19 style rules, post-filters and automatic editorial audit so the result goes unnoticed.
Generation with judgment.
Choose between 8 structures, 7 tones and 3 lengths. Long articles are generated by sections to avoid the quality drop GPT typically shows past 1200 words.
- Pillar articles of 2,700–3,300 words in a sectioned pipeline
- Extra blocks: FAQ, tables, pros/cons, CTA…
- Reusable templates per client or niche
The style that doesn't give you away.
19 numbered rules in the prompt catch typical tells: "not only X, but also Y", "it's crucial", "revolutionize", made-up figures… Automatic post-filters rewrite the most common patterns.
- Connector quotas: "Furthermore" max. 1 time per article
- Authorial voice with concrete cases, not empty phrases
- No made-up data: figures only if they come from your KB
The review you don't do.
After generating the article, the plugin classifies risk across 5 categories. If something smells like AI, it shows you highlighted inside the editor itself — you decide whether to publish, review or regenerate.
- Problematic phrases highlighted in the article
- No AI: detection by objective patterns and counters
- Panel in the WordPress editor sidebar
Zero hallucinations. The AI says what you know.
AI models make up figures, dates and quotes when they don't have concrete information. One false data point ruins the credibility of an entire article. Knowledge bases solve the problem: you load the verified material, the plugin injects it into every generation.
Japan welcomed over 35 million tourists in 2024, according to a recent JNTO study. The JR Pass currently costs 29,650 yen for 7 days, a 76% increase over the previous year.
Japan saw a record high in international tourism in 2024 after the post-pandemic reopening. The 7-day JR Pass remains the most popular option among travelers combining Tokyo, Kyoto and Osaka, though it's worth checking its current price before the trip.
Three steps to teach the AI what you know about your business.
Load what you know.
Build your bases with three methods: manually with PDF, Word or URL extractors; generating AI drafts from a topic; or importing up to 5,000 cards via CSV.
- PDF, Word, .txt, .md and URL extractors (up to 20 MB)
- Own vocabulary and blacklist per base
- One base per client, niche or product
The AI checks before writing.
When generating an article, the plugin turns the title into a vector and finds the 5–15 most relevant cards in your KB. That context is injected into the prompt as verified material.
- Precomputed embeddings per card
- Rule 19: no figure in the KB, no figure in the text
- Works in any language, without training
It knows what it knows.
Before adding titles to the queue, the plugin measures whether your KB covers the topic. If similarity falls below the configurable threshold, it flags the title with a warning so you can decide.
- Default threshold 35%, adjustable per base
- Flags with ⚠ in the jobs list for review
- Zero articles published with poor context
No surprises in costs.
4Linking doesn't bill tokens. You set up your own OpenAI API key and the AI calls go straight from your server to theirs. You pay exactly what you use, at the price OpenAI publishes.
You pay OpenAI directly. Not us.
Your content and your tokens travel only between two servers: yours and OpenAI's. 4Linking doesn't get in the middle, doesn't bill tokens and doesn't store what you generate.
Three more modules that add up, not pile up.
AI-generated images, multi-language translation and full pipeline automation. They're not the reason you'll buy 4Linking, but they're the reason you won't want to switch.
A featured image for every article.
From the title and context, the plugin generates an original image with gpt-image-1 or gpt-image-1-mini. It optimizes it, resizes it and assigns it as the featured image.
Every language, a real post.
Translations are independent posts with their own URL, slug and sitemap. Not hidden variants: each language with its own SEO, as if you'd written it from scratch.
The pipeline, hands-off.
Schedule a list of titles and a frequency. The plugin generates, links, translates and publishes in the background with Action Scheduler. Without blocking the admin.
4Linking against every other internal linking plugin
Yoast and Link Whisper are the go-to names for internal linking in WordPress. Both do a good job at what they do, but neither combines AI content generation, semantic linking by embeddings and automatic editorial audit in a single plugin.
Yoast and Link Whisper are valuable tools in their niche. This table compares only internal linking and content generation features. Yoast has general SEO capabilities (sitemaps, schema, redirects) that 4Linking doesn't cover and that can coexist perfectly with our plugin.
