InLinks vs Link Whisper in 2026: Entity knowledge graph vs WordPress in-editor suggestions
One builds a cross-site knowledge graph and prices monthly. The other lives inside the WordPress editor and bills once a year. Same job, different assumptions about your stack.
InLinks
Link Whisper- InLinks suggests links from a knowledge graph of entity relationships across a site. Link Whisper scans existing content for topical overlap directly inside the WordPress editor and suggests a link as you type.
- Link Whisper only installs on WordPress. InLinks crawls any site and can insert links automatically through a JavaScript snippet, so it also covers Webflow, Shopify, or custom-built sites.
- InLinks bundles content gap analysis and automatic schema markup generation with its linking tool. Link Whisper has neither; it stays focused on internal linking, orphan detection, and broken link reporting.
- Link Whisper is a one-time annual license from $77/year for one site to $167/year for unlimited sites. InLinks is a monthly subscription from $49/month for one site to $196/month for multiple sites, so the cheaper option flips depending on how many sites and years you're counting.
- Link Whisper has dedicated orphan page detection and broken internal link reporting built into its site audit. InLinks does not name either as a specific feature.
- InLinks includes API access starting on its $49/month Freelancer plan. Link Whisper has no API on any tier, including the $167/year unlimited-site license.
- Neither tool tracks brand mentions in ChatGPT, Gemini, or other AI chatbot answers. InLinks says so directly in its own FAQ, and Link Whisper makes no AI visibility claim at all.
InLinks and Link Whisper both promise to fix the same neglected task: internal linking that never gets done systematically because it's tedious to research and implement by hand. InLinks approaches it by crawling a site, mapping the entities each page covers, and generating link suggestions from that knowledge graph, whether the site runs on WordPress, Webflow, or anything else. Link Whisper stays inside the WordPress editor itself, scanning your existing content as you write and inserting a suggested link with one click, backed by a site-wide report for orphaned and broken pages. InLinks charges monthly and adds content gap analysis and schema markup on top of linking; Link Whisper charges once a year per site and does one job without an API or knowledge graph layer. Which one wins depends less on feature count and more on what CMS you're running and whether you want linking bundled with topical research or isolated and cheap.
The tools at a glance
InLinks
Entity-based internal linking and knowledge graph optimization
InLinks crawls a site, identifies the entities each page covers, and builds a knowledge graph of how those entities relate to each other. Link suggestions come out of that graph instead of keyword overlap, so a page about "email deliverability" can link to a page about "SPF records" even though the two pages never share a phrase. Links can be inserted from the recommendations manually, or automatically through a JavaScript snippet, which is what makes InLinks usable outside WordPress.
Two features sit on top of the linking layer. Content gap analysis compares a site's entity coverage against competitors and reference sources, surfacing topics the site is expected to cover but doesn't. Schema markup generation writes structured data for pages based on the entities InLinks has already identified, without requiring per-page manual configuration.
Pricing starts with a free plan for testing, then $49/month for a single site (Freelancer), $196/month for multiple sites (Agency), and custom Enterprise pricing. API access is included from the Freelancer tier up, but there is no white-label option on any plan.

Link Whisper
WordPress plugin that suggests relevant internal links as you write and audits your entire site structure
Link Whisper operates directly inside the WordPress editor. As you write or edit a post, it scans your existing published content and surfaces link suggestions with a recommended anchor text and target URL, and accepting one adds the link without leaving the editor. There's no separate dashboard to check and no crawl to wait on; the suggestion appears while you're typing.
Beyond the in-editor suggestions, Link Whisper runs a site-wide audit that flags orphaned pages (pages with zero inbound internal links) and broken internal links returning 404s. An anchor text distribution report shows whether you're over-relying on the same exact-match phrase across your link structure.
Pricing is an annual license rather than a subscription: $77/year for one site, $117/year for three, and $167/year for unlimited sites. There's no API and no integration outside WordPress admin, and the tool only works if your site is on WordPress in the first place.
| Feature | Basic $77/year (1 site) | Standard $117/year (3 sites) | Professional $167/year (unlimited sites) |
|---|---|---|---|
| WordPress sites | 1 | 3 | Unlimited |
| Inline link suggestions | Yes | Yes | Yes |
| Orphan page detection | Yes | Yes | Yes |
| Broken link detection | Yes | Yes | Yes |
| Auto-linking rules | No | Yes | Yes |
| Priority support | No | No | Yes |

Which should you choose?
InLinksLink WhisperInLinksLink WhisperLink WhisperInLinksLink WhisperThe deciding factor is rarely feature count, it's whether your site is on WordPress and whether you want linking bundled with broader entity research. Link Whisper is cheaper over multiple years for a WordPress-only portfolio, and its in-editor workflow means links actually get added while a post is being written, not in a separate review pass later. InLinks costs more per year for a single site but earns that back once you add the content gap analysis, schema markup, and cross-CMS support, none of which Link Whisper offers at any price.
Bottom line
Choose Link Whisper if every site you manage runs on WordPress and you want link suggestions to appear while you're actually writing, with a licensing model that doesn't compound monthly. Choose InLinks if you run anything outside WordPress, want the knowledge graph and content gap analysis as part of the same subscription, or need API access to move linking data into your own reporting. Neither tool tracks how a brand shows up in AI chatbot answers, so if that's the actual goal, look elsewhere.
Frequently asked questions
Is InLinks or Link Whisper better for a site that isn't built on WordPress?
InLinks is the only option of the two for a non-WordPress site. Link Whisper is a WordPress plugin with no version for Webflow, Shopify, or custom-built sites, while InLinks crawls any site and inserts links through a JavaScript snippet instead of a plugin.
Does Link Whisper have an API for pulling linking data into another tool?
Link Whisper has no API on any of its three tiers, including the $167/year unlimited-site license. InLinks includes API access starting on its $49/month Freelancer plan, which makes it the better fit if you need to move linking data into a separate reporting system.
Which tool has cheaper long-term pricing for an agency managing multiple WordPress sites?
Link Whisper is cheaper for a WordPress-only agency at scale: the Professional tier covers unlimited sites for $167 per year, or about $14 per month total regardless of site count. InLinks' Agency plan is $196 per month for multiple sites without a published unlimited-site cap, so the cost gap widens the more sites you add.
Do InLinks or Link Whisper track brand mentions in ChatGPT or AI Overviews?
Neither tool tracks brand mentions in AI-generated answers. InLinks states directly in its own FAQ that it focuses on entity coverage and internal linking rather than AI chatbot citations, and Link Whisper makes no AI visibility claim anywhere in its feature set. Both are traditional SEO tools, not AI visibility monitors.
Can Link Whisper insert links automatically without me reviewing each one?
Auto-linking rules on the Standard and Professional tiers can insert links to specified target pages automatically based on keyword triggers, though the default workflow requires manual acceptance of each suggestion. InLinks also supports automatic insertion, through a JavaScript snippet rather than a WordPress-native rule engine, which is the version that works on non-WordPress sites.
What's the real difference between InLinks' knowledge graph and Link Whisper's link suggestions?
InLinks builds a knowledge graph of entities across your site and connects pages based on topical relationship, so two pages can link even if they never share an exact phrase. Link Whisper scans your existing content for relevant overlap as you write and surfaces a suggestion inside the editor, which is simpler to understand at a glance but doesn't model entity relationships the way InLinks does.
