ContentShake

ContentShake AI, now integrated into Semrush as the Content Toolkit, is an AI-powered content creation and optimization solution designed to help marketers research topics, generate SEO-focused articles, optimize drafts, and publish content. Semrush describes the current Content Toolkit as a workflow that combines its proprietary SEO data with AI to take content from ideation through publication.

ContentShake was originally launched as a standalone Semrush App Center application. In 2025, Semrush incorporated it into the main platform and renamed the product Content Toolkit. The underlying purpose remains focused on helping content marketers create content without having to perform every research, writing, and optimization task manually.

The Content Toolkit begins with content ideation. Its Topic Finder provides data-driven topic suggestions, including weekly and country-specific ideas. Users can then turn a topic into an SEO brief containing keywords, content structure, and competitor insights before moving into AI-assisted article generation.

Its AI Article Generator creates long-form content using Semrush data. The platform is designed to produce content that is optimized for both traditional search and newer AI-search experiences. Semrush’s current Content Toolkit also includes an AI-search optimization feature that analyzes content against factors associated with higher citation rates in AI-generated answers.

Content optimization is another central part of the product. The Content Optimizer provides recommendations related to SEO, tone, readability, and content quality. This allows users to improve an article after generation rather than simply publishing the first AI-generated draft.

The platform also includes Brand Voice, allowing teams to create and save writing styles so that AI-generated content can remain more consistent with their brand. The current Base Content Toolkit plan supports up to 50 brand voices.

Content creation is not limited to text. The Content Toolkit includes AI image generation, while users can also search for images through Unsplash or upload their own visuals. Semrush says users can publish content and images directly to WordPress.

The current Content Toolkit also supports content repurposing. Semrush describes the workflow as extending from articles into social media posts and email content, helping marketers reuse content across multiple channels.

Publishing and collaboration are also built into the workflow. The platform currently integrates with WordPress for direct publishing, Mailchimp for email campaigns, Semrush Social Poster for social distribution, and Canva for importing visuals.

For marketers who already use Semrush, Content Toolkit has a significant advantage because it operates on the same broader Semrush data ecosystem. Instead of using a generic AI writer separately from SEO research tools, users can combine topic discovery, SEO briefs, AI writing, optimization, AI-search optimization, repurposing, and publishing within the Semrush environment.

Pricing

The current Semrush Content Toolkit is priced at:

• Base — $60/month billed annually
• 7-day free trial
• Additional users — $20/month each
• SEO Boosted Articles: 5 included per month, with 10 additional articles available for $30/month
• Enterprise: Custom pricing

The Base plan includes unlimited standard articles, five SEO-boosted articles per month, SEO briefs, content ideas, content optimization, AI writing tools, AI image generation, and up to 50 brand voices.

The current pricing is different from older ContentShake AI listings that described a standalone $60/month Unlimited Plan. The product is now packaged as the Content Toolkit within Semrush.

Review

ContentShake AI was a strong choice for marketers who wanted AI writing combined with Semrush’s SEO data, and its current evolution into the Content Toolkit makes that workflow broader rather than eliminating it. The product now covers topic discovery, SEO briefing, AI article generation, optimization, AI-search optimization, repurposing, visual creation, collaboration, and publishing.

Its biggest advantage is the connection between AI content creation and search data. Instead of relying solely on a general-purpose language model, the tool uses Semrush’s data to inform content ideas, briefs, keywords, competitor research, and optimization. Semrush also specifically positions the Content Toolkit for optimizing content for both Google and AI search platforms.

The main limitation is that the product is most valuable to people already interested in SEO and content marketing. Users looking only for a simple AI writing assistant may find Semrush’s broader ecosystem more extensive than necessary. The $60/month entry price is also higher than many basic AI writing tools.

For SEO-focused marketers, publishers, agencies, and businesses already using Semrush, however, Content Toolkit provides a practical end-to-end content workflow with research, generation, optimization, and publishing in one environment.
