Adding internal links by hand is slow — and the tools that automate it charge you by the suggestion.

Most AI internal-linking plugins meter their suggestions with credits and renew every year, so the more you link the more you pay, and your post content is sent off to someone else’s server to be scored. For a blog with hundreds of posts, “just add internal links” turns into a recurring bill.

JnK Linkweave does the whole thing on your own server. It reads your existing posts and pages and suggests contextually relevant internal links right inside the editor, ranks them with TF-IDF and BM25 in PHP, and applies keyword auto-linking rules at render time — with no external service, no per-suggestion fees, and no post content ever leaving your site. Index as many posts and create as many rules as you like; nothing is metered.

It’s built for the people who actually maintain content at scale: bloggers, SEO and content teams, agencies, and membership or course sites that want serious internal linking without a per-credit meter.

What you get in the free version

Editor sidebar with ranked internal-link suggestions for the current post (Gutenberg + Classic Editor / TinyMCE).
Server-side TF-IDF + BM25 ranking — all scoring runs in PHP. No external API calls, no per-request fees, no content sent off-site.
“Posts that should link here” — inbound-link opportunities surfaced right in the editor.
Unlimited keyword auto-linking rules — keyword → URL rules with per-post and per-site caps, case sensitivity, target="_blank", and rel="nofollow". No cap on how many rules you create or activate.
Orphan-page report — find published posts with zero inbound internal links.
Broken internal-link scan — a daily check across your link graph flags internal links that 404.
Inbound link counts — see which posts hold the most internal link equity.
Post-type control — choose which post types are indexed and eligible as link targets.
Background indexing via Action Scheduler — rebuilds never run inline on save_post.
Tag-aware rewriting — rules skip content inside <a>, <code>, <pre>, headings, and shortcodes, so existing markup is never mangled.

Get Pro

Pro is a flat license — from $59/year (or a one-time lifetime option), with no per-suggestion metering ever. Cancel any time and the free tier keeps working forever. See pricing. Pro adds:

AI re-ranking (BYOK) — sharpen suggestion order with your own OpenAI or Anthropic key.
Google Search Console targeting — import your GSC Queries export to steer links toward pages that already earn search clicks.
Yoast / Rank Math focus-keyword boost — rank suggestions using the SEO focus keyphrases you already set.
One-click auto-link map — build an internal-link map from your topical clusters in a single click.
Inbound-link bulk-apply — add contextual links to the current post into several related posts at once.
Cross-site / portfolio linking (Agency) — suggest links between the sites on your license.
Bulk review & approve — insert several editor suggestions at once.
One-click broken-link repair — unlink or repoint dead internal links, one at a time or all at once.
Bulk URL changer with per-batch rollback, and orphan-report CSV export, and internal-link click analytics (first-party, on your own server).

Bundle JnK Linkweave with Trinity Forms or EntryVault for ~20% off, or take all three for ~25% off — one checkout, one renewal, a license key per plugin.

Why JnK Linkweave instead of credit-metered tools like Link Whisper?

No per-suggestion meter. Tools like Link Whisper meter AI suggestions with credits; when the credits run out you buy more. JnK Linkweave’s suggestions are unlimited because they’re computed on your own server.
Your content stays put. Credit-metered tools send your post content to their servers for scoring. Linkweave ranks everything locally in PHP — no content ever leaves your site.
Flat pricing, with a lifetime option. Instead of a yearly credit plan, Pro is a flat license from $59/year, and every tier has a one-time lifetime option (about four years of the annual price). The free tier stays free.
The free tier is a real product, not a locked demo — unlimited rules, orphan/inbound/broken reports, and editor suggestions with no submission caps.

Privacy

In JnK Linkweave’s free build, relevance scoring runs entirely in PHP on your server — no post content ever leaves your site. There is no phone-home and no telemetry.

External services

This plugin does not send your content or data to any third-party service.

The only outbound HTTP requests it makes are to your own site: the daily broken-link scanner issues a lightweight HEAD request to each internal link target (a URL on your own domain) to check whether it still resolves. These are self-requests to your site, filtered to your own home URL — no external endpoint is contacted, and nothing is transmitted off your server.

Development

JnK Linkweave is fully open source (GPLv2-or-later) and ships entirely uncompiled
alongside its build output, so no external download is needed to read or rebuild it.

All PHP is human-readable and shipped as-is (there is no PHP build step).
The block-editor sidebar’s React SOURCE is included in this plugin under
editor/src/ (Sidebar.jsx and friends). The compiled files under editor/build/
(index.js and its CSS) are generated directly from that source — nothing under
editor/build/ is authored by hand.
The build uses @wordpress/scripts (https://www.npmjs.com/package/@wordpress/scripts),
with the source and output directories set explicitly in package.json:

npm install
npm run build (runs: wp-scripts build –webpack-src-dir=editor/src –output-path=editor/build)

Running that regenerates the build output from the source. No other build step is required.
