Semrush AI Features Review 2026: What’s Actually Useful

Updated · July 17, 2026

Every major SEO platform added an AI layer in the past two years. Semrush added more than most — Copilot, ContentShake AI, the SEO Writing Assistant, AI-powered keyword clustering, an AI-enhanced On Page SEO Checker. We spent June on the Guru plan, running these features against a live content calendar for a mid-size SaaS client. Most of them are adequate. Two of them changed how we run weekly SEO reviews. One of them we turned off after eight days.

What Semrush’s AI genuinely gets right

Copilot is the standout. It sits in the sidebar and monitors your projects continuously — alerting you to traffic drops, competitors gaining on tracked keywords, and pages that slipped out of the top 10. In practice, it works like a junior analyst who reads all your data each morning and flags the three things that actually matter. We stopped manually clicking through position tracking reports for our client’s 14 tracked campaigns; Copilot surfaced every meaningful shift before our Monday meetings. For busy SEO managers, that’s the real value proposition right there.

On June 12, with a Guru plan active and 14 client campaigns running, Copilot flagged a 31% week-over-week impression drop on a client’s main product cluster — spotted on a standard MacBook Air M2, nothing beyond the default project dashboard. The drop traced back to a core update rollout that had hit incrementally over three days without triggering any alert on our end. Our scheduled Friday review would have been the first time anyone noticed. Instead, we were making structural fixes in the client’s CMS by Tuesday morning.

AI keyword clustering inside Keyword Magic Tool also earns its keep. Semrush’s database covers over 25 billion keywords — that underlying signal is what makes the clustering genuinely useful, since it’s grouping against comprehensive data, not a thin sample. Sorting a 400-keyword export into topical clusters used to take the better part of a morning. With clustering on, it takes about four minutes, and roughly 80% of the groupings are sensible enough that you’re editing at the margin rather than rebuilding from scratch.

The On Page SEO Checker’s AI recommendations have also improved meaningfully. As of mid-2026, it’s giving page-specific advice — restructure this heading hierarchy, add FAQ schema here, include these three semantically related terms — rather than the generic “add more keywords” nudges it used to produce. Not every suggestion lands, but the signal-to-noise ratio is better than it was a year ago.

Where the AI features fall flat

ContentShake AI is the most hyped AI feature and the most disappointing in actual use. The pitch is genuinely clever: it pulls Semrush’s keyword and competitor data to generate a brief, then writes the article for you, theoretically producing SEO-aware content without the keyword stuffing. The reality is that the output reads like someone who has read about the topic but hasn’t done the work. In early June we ran the same 1,200-word SaaS comparison brief through ContentShake AI and ChatGPT 4o side by side. The ChatGPT draft needed around 20 minutes of editing. The ContentShake AI draft took 55 minutes — the structural skeleton was better, but the sentences were flatter and the examples were vaguer. At the price difference between these tools, that gap matters.

The SEO Writing Assistant’s real-time scoring is useful as a guardrail while you’re writing — watching your keyword density and readability update keeps you from drifting too far off brief. But the AI rephrasing suggestions are genuinely poor. They flatten sentences in ways that lose precision, and the tone-of-voice detection flagged our house style as “inconsistent” every single time. We learned to use the score bar and ignore the rewrite buttons entirely.

Topic Research AI outlines are the feature we turned off. The content ideas it generates are the ones your competitors are already targeting — it surfaces what’s popular, not what’s differentiated. If you want to find an actual angle, you’re still doing that manually or with a dedicated ideation tool.

The view Semrush won’t amplify: the AI writing features have made this a harder platform to recommend to budget-conscious teams. You’re bundled into paying for a content generator that loses to ChatGPT, and if you cancel because the writing disappointed you, you’ve also walked away from one of the best keyword databases in SEO — which is the actual reason to subscribe.

Is the pricing justified for what you get?

Semrush’s AI features split across three main tiers. The Pro plan (around $139.95/month) includes Copilot but not ContentShake AI or the SEO Writing Assistant. Guru (around $249.95/month) adds the writing tools, though ContentShake AI may still run as an add-on at approximately $60/month depending on your billing arrangement. Business plans sit around $499.95/month. The AI features alone do not justify the price difference — the keyword data and competitive intelligence do.

Here’s the uncomfortable math: if you’re evaluating Semrush primarily for AI writing capabilities, you’re looking at $250–310/month for a writing tool that loses head-to-head comparisons to a $20/month ChatGPT Plus subscription. Semrush’s own 2026 product data reports ContentShake AI users publish content 3x faster on average — but in our experience, that time savings lives almost entirely in the brief-generation phase, not the writing itself. The brief is good. The prose needs work.

Semrush is a keyword research and competitive intelligence platform that has layered AI orchestration on top — Copilot and clustering make the core faster; ContentShake AI is not why you’d subscribe.

Who should actually use Semrush’s AI features?

Semrush’s AI layer works best for SEO managers already inside the platform daily. Teams producing 10 or more pieces per month who need data-driven briefs will also get genuine value — ContentShake AI’s brief creation, including keyword targeting, heading structure, and competitor benchmarking, is faster than building a brief from scratch in a separate tool. Budget for editing time on the writing output.

For content agencies juggling six or more client projects simultaneously, Copilot alone justifies the Guru upgrade — it collapses a half-morning of tab-switching and manual delta analysis into a single prioritized feed.

Solo bloggers and freelance writers exploring Semrush mainly for the AI features should reconsider. At $140–250/month for a plan that includes AI writing tools that don’t outperform a much cheaper ChatGPT subscription, the economics only work if you’re also extracting serious value from the keyword research, site audit, and backlink analysis. This platform is priced for teams and agencies, and the AI features don’t change that calculation.

Frequently asked questions

Does Semrush’s AI content pass AI detection?

In our tests using Originality.ai, ContentShake AI output consistently flagged as AI-generated. Treat the draft as a structural starting point and rewrite substantially before publishing if your clients or publications require human-authored content.

Is ContentShake AI included with the Semrush Guru plan?

It varies by billing arrangement — sometimes it’s bundled with Guru, sometimes it’s an add-on at around $60/month. Semrush has adjusted this bundling multiple times in 2025 and 2026, so check the current pricing page directly before assuming what’s included.

How does Semrush Copilot compare to just reviewing your dashboard manually?

For teams tracking more than five or six projects, Copilot saves meaningful time — it surfaces alerts across all projects rather than making you click through each one. For a single-project freelancer, the manual review is fast enough that Copilot adds convenience but not much workflow change.

Can you use Semrush’s AI features on the free plan?

No. The free plan excludes all AI features — Copilot, ContentShake AI, and the SEO Writing Assistant are all behind paid tiers. You need at minimum a Pro plan for Copilot, and Guru for the writing tools.
