In their own words
Core+ Links
Core+ Links is a self-hosted WordPress plugin that finds and manages internal links using a local index of site content. In the Gutenberg block editor, its sidebar ranks possible destinations with eight weighted signals and shows match strength. You can revise anchor text, insert a suggestion in one click, or dismiss it. Keyword rules scan pages for matches that you review before applying. A change history can undo one edit, a complete run, or links created by a keyword rule. Reports identify orphan pages without inbound links and underlinked pages with fewer links than their importance calls for. Link Health flags links to unpublished, trashed, or missing pages, but does not inspect external URLs over HTTP. Indexing, ranking, auto-linking, and Link Health run on your server and database. The free plan is permanent and includes background indexing and scheduled reindexing. Requirements are WordPress 6.6+, PHP 7.4+, and Gutenberg. Upcoming Pro plans have no listed prices.
Link Whisper
Link Whisper is a WordPress plugin and Shopify app for managing internal links. It suggests links for posts, which users can review before adding, and can draw on Google Search Console data and keywords from Yoast SEO, Rank Math, All In One SEO, and SEOPress. It supports editors and builders including Classic Editor, Gutenberg, Beaver Builder, Cornerstone, Elementor, and Divi. The plugin can process Advanced Custom Fields content and configured custom metafield-based content. Premium includes reports on link statistics, domain linking, clicks, and broken links. Licensed sites can suggest outbound links to one another, but inbound cross-site suggestions are not supported. Free access includes manual insertion of outbound suggestions; a limited-time Premium trial is available, and paid plans start at $97/yr. The maker says Premium does not send site content or personally identifiable information to its servers, though license checks transmit the license key, site URL, and subscription level. AI processing sends only selected post content to OpenAI; click tracking may store visitor IP addresses and site IDs on the customer's site.
