Link Whisper vs Sight AI in 2026: WordPress internal linking plugin vs Slack-native AI content and visibility agent
One plugin finds internal link opportunities inside WordPress for $77 a year. The other is a $49-a-month Slack agent that writes, publishes, and tracks your brand across five AI engines.
Link Whisper
Sight AI- Sight AI tracks brand visibility across ChatGPT, Claude, Perplexity, Gemini, and Grok. Link Whisper has no AI-visibility tracking of any kind; its scope is internal links within WordPress content.
- Link Whisper is WordPress-only. Sight AI publishes to WordPress, Webflow, Framer, and Shopify.
- Sight AI includes a 7-day free trial with 7 articles included. Link Whisper has no advertised trial of any length.
- Link Whisper bills once a year starting at $77. Sight AI bills monthly starting at $49, plus $29/month add-ons for each extra team member or site.
- Neither tool offers an API or white-label delivery on any plan, which rules out both for agencies needing programmatic access or branded client reporting.
- Link Whisper's orphan page and broken internal link detection have no equivalent in Sight AI, which is not built to audit an existing site's internal link structure.
Link Whisper and Sight AI both get filed under content tooling, but they are aimed at different problems and different team sizes. Link Whisper is a single-purpose WordPress plugin: it reads content you already published and suggests internal links you missed, then reports on orphan and broken links across the site. Sight AI is a broader AI agent that researches, writes, and publishes articles across four CMS platforms, approves actions through Slack replies, and simultaneously tracks how your brand shows up in ChatGPT, Claude, Perplexity, Gemini, and Grok. If your only gap is internal linking on an existing WordPress site, Sight AI is overbuilt for the job. If you want one subscription that produces content and tells you whether AI models are actually mentioning your brand, Link Whisper does not even attempt that second half.
The tools at a glance
Link Whisper
WordPress plugin that suggests relevant internal links as you write and audits your entire site structure
Link Whisper installs as a WordPress plugin and works from inside the post editor. As you write in Gutenberg or Classic Editor, it scans your published content and surfaces internal link suggestions with a recommended anchor and target URL, added to the post with one click. The site-wide report adds orphan page detection, a broken internal link checker, and an anchor text distribution report on top.
What Link Whisper does not do is anything related to AI visibility. It has no concept of how your brand appears in ChatGPT or Gemini, no content generation, and no monitoring beyond your own site's internal link graph. That narrow scope is also its strength: it does one job with no bloat, and the Professional tier at $167/year covers unlimited WordPress sites for a fraction of what a subscription tool would charge over the same period.
The limitations are the WordPress lock-in and the lack of any API or export layer. If your stack includes a non-WordPress site, or you want internal link data flowing into an external dashboard, Link Whisper cannot do either.

| Inline editor suggestions | Yes | Yes | Yes |

Sight AI
AI SEO and content marketing agent that lives in Slack, writes and publishes articles, and tracks brand visibility across ChatGPT, Claude, Perplexity, Gemini, and Grok
Sight AI runs as an agent you direct through a chat interface or Slack, handling keyword research, article writing, and publishing to a connected CMS such as WordPress, Webflow, Framer, or Shopify. Scheduled automations let it run daily or weekly without manual triggers, pausing only when a real decision needs a human, then posting the recommendation with supporting numbers directly to a Slack channel. A reply in Slack approves the action and the agent executes it.
The visibility side is not an afterthought: Sight AI tracks brand and content visibility across ChatGPT, Claude, Perplexity, Gemini, and Grok, refreshed daily on Pro and above, alongside Google Search Console in the same dashboard. Article generation runs on Claude Sonnet 4.5, and published content is auto-submitted to Google's sitemap and Bing IndexNow to speed up indexing.
What is missing is anything built specifically for agencies: no API on any plan and no white-label reporting, so client-facing dashboards are not part of the package. Costs also compound as a team grows, since extra members and extra sites are each $29/month on top of the base plan, and tracked AI prompts are capped at 10 on the entry Starter tier.
| Feature | Starter $49/mo | Pro $129/mo | Advanced $499/mo |
|---|---|---|---|
| AI engines tracked | 5 | 5 | 5 |
| Tracked AI prompts | 10 | 50 | 250 |
| Scheduled automations | No | Yes | Yes |
| API access | No | No | No |
| White label | No | No | No |

Considering AI Peekaboo alongside Link Whisper and Sight AI?
Sight AI tracks brand visibility across five AI engines but offers no API and no white-label reporting on any plan, and Link Whisper does not track AI visibility at all. AI Peekaboo ships a read and write API on every plan from $50 per month, along with white-label reports and a Looker Studio connector, giving SEO agencies programmatic access to AI visibility data without a Slack-agent workflow or per-seat add-on fees standing in the way.

Link WhisperSight AISight AILink WhisperSight AILink WhisperSight AIThese tools sit at opposite ends of the same category. Link Whisper is a $77-a-year specialist that fixes one specific problem inside WordPress and stops there. Sight AI is a much broader monthly subscription that writes content, publishes it across four platforms, and layers in AI engine visibility tracking that Link Whisper does not attempt at all. A WordPress-only publisher who just needs cleaner internal links is overpaying with Sight AI's per-seat and per-site fees. A team that wants to know whether ChatGPT or Gemini is actually mentioning their brand gets nothing from Link Whisper regardless of price.
Bottom line
Buy Link Whisper if your WordPress site already has the content it needs and the gap is internal linking specifically, and you would rather pay once a year than manage a subscription. Start Sight AI's 7-day trial if you want one tool that writes and publishes articles across multiple platforms while tracking how your brand appears in ChatGPT, Claude, Perplexity, Gemini, and Grok, and you are prepared to budget for per-seat and per-site add-ons as the team grows. Agencies that need API access or white-label reporting for AI visibility data specifically will need to pair either tool with something like AI Peekaboo, since neither offers that layer today.
Frequently asked questions
Does Sight AI replace what Link Whisper does for internal linking?
Not directly. Sight AI includes automated internal linking as a feature on its Pro tier and above, but it is not framed as a dedicated audit tool the way Link Whisper is, and it has no equivalent to Link Whisper's orphan page report or broken internal link checker. A WordPress site that specifically needs those audit views is still better served by Link Whisper.
Which AI engines does Sight AI track that Link Whisper does not track at all?
Sight AI tracks brand and content visibility across ChatGPT, Claude, Perplexity, Gemini, and Grok, refreshed daily on its Pro tier and above. Link Whisper has no AI visibility tracking feature whatsoever; it is scoped entirely to internal linking within a WordPress site.
Is Link Whisper cheaper than Sight AI over a year?
For a single site, yes: Link Whisper's Basic tier is a one-time $77/year charge, while Sight AI's Starter plan runs $49/month, or $588/year before any per-seat or per-site add-ons. The comparison only holds if you actually need what each tool does, since Link Whisper has no content generation or AI visibility tracking and Sight AI is not built as a dedicated internal-link auditor.
Can Sight AI publish to a WordPress site the same way Link Whisper works with WordPress?
Yes, Sight AI connects to WordPress along with Webflow, Framer, and Shopify for direct publishing. Link Whisper only works inside WordPress and has no publishing capability of its own; it operates strictly on content that already exists in your WordPress editor.
Do either Link Whisper or Sight AI offer an API for developers?
No. Neither tool currently offers API access on any pricing tier, so teams needing programmatic access to link data, content, or AI visibility scores will need a different tool for that layer.
Which tool has a free trial, Link Whisper or Sight AI?
Sight AI includes a 7-day free trial with 7 articles included on every plan. Link Whisper does not advertise a free trial; its Basic tier at $77/year is the lowest-cost way to try it.
