ContentShake AI is Semrush’s AI content generation tool that turns a single keyword into a publish-ready, SEO-optimized article using Semrush’s own SERP and competitor data. Semrush rebranded it as the Content Toolkit in 2026, and it costs $60 per month for 5 SEO-boosted articles plus unlimited standard drafts.
What Is ContentShake AI?
ContentShake AI is Semrush’s AI writing product that generates topic ideas, outlines, and full articles by pulling live keyword and SERP data from Semrush’s own database. Semrush launched it in April 2023 as “ContentShake,” added the AI Chat feature in November 2023, and introduced real-time SERP-based SEO scoring in April 2024.
Semrush Holdings, Inc. (NYSE: SEMR) built ContentShake AI as a standalone app inside the Semrush App Center, separate from the core SEO Classic subscription. The tool draws on Semrush’s keyword database, which the company reports covers more than 25 billion keywords, to generate outlines and drafts that reflect what already ranks for a target term. In 2026, Semrush folded ContentShake AI into a broader offering called the Content Toolkit, keeping the same core writing workflow under a new name.

What Are ContentShake AI’s Key Features?
ContentShake AI covers the full workflow from topic research to publishing, structured around five core functions.
- Generate topic ideas using Semrush’s Topic Finder, which ranks suggestions by search volume, keyword difficulty, and search intent and tags each one (for example, as a “low-hanging fruit” opportunity).
- Build article outlines automatically by analyzing the top-ranking pages for a target keyword and structuring headings around what already performs in search.
- Draft full articles in one of two modes: unlimited standard articles, or SEO-boosted articles that pull in real-time SERP data and competitor insights, capped at 5 per month on the base plan.
- Score content on 3 dimensions — SEO potential, readability, and originality — with a built-in plagiarism checker flagging duplicate text before publishing.
- Publish directly to WordPress through a dedicated plugin, or export finished drafts to Google Docs without leaving the editor.
- Rewrite text with AI Chat, a conversational interface added in November 2023 that lets a user request rewrites, expansions, summaries, or supporting images through a prompt bar.
How Much Does ContentShake AI Cost?
ContentShake AI costs $60 per month for 5 SEO-boosted articles and unlimited standard articles, billed through Semrush’s own pricing page. A free version caps output at 3 articles per month and 3 topic ideas per week.
According to Semrush’s official ContentShake AI pricing page, the $60/month plan includes a 7-day free trial before billing starts, and payment is accepted via Visa, Mastercard, Discover, American Express, and UnionPay. Users who need more than 5 SEO-boosted articles in a month can buy an add-on pack of 10 extra SEO-boosted articles for $30, or upgrade to a full Semrush SEO Classic plan (Pro starts at $139.95/month), which raises the monthly SEO-boosted article limit to 20 automatically. Semrush does not charge separately for standard (non-SEO-boosted) articles — that tier remains unlimited on the $60/month plan.
| Plan | Price | SEO-Boosted Articles | Standard Articles |
|---|---|---|---|
| Free | $0 | 0 | 3/month |
| ContentShake AI (paid) | $60/month | 5/month | Unlimited |
| Extra article pack | +$30 | +10 articles | — |
| Bundled with Semrush Pro ($139.95/mo) | — | 20/month | Unlimited |
What Are the Pros and Cons of ContentShake AI?
ContentShake AI’s biggest advantage is direct access to Semrush’s live SEO data inside the writing process; its biggest limitation is a 5-article SEO-boosted cap on the base plan.
Pros:
- Pulls real-time SERP and competitor data into outlines instead of relying on a static training dataset.
- Topic Finder labels each suggestion by opportunity level (search volume, keyword difficulty, intent), which speeds up idea selection.
- One-click WordPress publishing removes the copy-paste step between drafting and posting.
- Built-in plagiarism checker runs before publishing, without a separate subscription.
- Aggregate third-party review scores place it at 4.8/5 across roughly 400 ratings on comparison sites such as AI Choice Guide.
Cons:
- The $60/month plan caps SEO-boosted articles at 5 per month; high-output teams need the $30 add-on pack or a full Semrush subscription.
- AI-generated drafts require substantial human editing for factual accuracy, nuance, and brand voice before publishing.
- Full value depends on the underlying Semrush keyword database, so the tool delivers less benefit to users outside the Semrush ecosystem.
- Output can read as generic or repetitive on broad topics without specific, detailed prompts.
How Does ContentShake AI Compare to Jasper AI?
ContentShake AI wins on built-in SEO data and price; Jasper AI wins on brand-voice customization and multi-channel content templates. ContentShake AI starts at $60/month with SEO data included by default, while Jasper AI’s Creator plan starts near $49/month but requires separate SEO tool integrations for competitor data.
| Factor | ContentShake AI | Jasper AI |
|---|---|---|
| Starting price | $60/month | ~$49/month (Creator plan) |
| Native SEO/SERP data | Built-in, from Semrush’s database | Requires third-party integration |
| Brand voice training | Basic tone settings | Advanced brand voice profiles |
| WordPress publishing | Native plugin | Via Zapier/API |
| Best for | SEO-first blog content | Multi-channel marketing copy |

Who Should Use ContentShake AI?
Solo bloggers, small content teams, and existing Semrush subscribers get the most value from ContentShake AI, since the tool’s core advantage — live SEO data — only compounds when paired with the rest of Semrush’s toolkit.
- Solo bloggers and small business owners who need SEO-informed drafts without hiring a dedicated SEO strategist.
- Content marketers already on a Semrush SEO Classic or Semrush One plan, since bundling raises the SEO-boosted article limit to 20/month at no extra AI-tool cost.
- Small agencies producing fewer than 15 SEO-focused articles per month, where the $60/month base price stays cheaper than hiring freelance writers per article.
ContentShake AI is not the right fit for teams needing more than 20 SEO-boosted articles monthly without a full Semrush subscription, or for writers who need multi-channel ad copy, social captions, and long-form blog content from a single platform.
What Are the Best Alternatives to ContentShake AI?
- Jasper AI focuses on brand-voice-trained content across blog posts, ads, and social copy rather than SEO-first blog articles alone — read the full Jasper AI Review for pricing and feature details.
- Frase builds SEO content briefs and outlines from live SERP analysis without requiring a full marketing-suite subscription — see the Frase Review for a breakdown of its brief-building workflow.
- Copy.ai targets short-form marketing copy and workflow automation rather than long-form SEO articles — check the Copy.ai Review for its template library and pricing tiers.

Final Verdict
