ContentShake AI is now the Semrush Content Toolkit

Semrush's ContentShake AI addresses now redirect to semrush.com/content/, which Semrush titles Content Toolkit. The Internet Archive shows the redirect in place by 15 September 2025.

contentshake.com, which we linked before, is a domain-for-sale page.

Checked October 3, 2026
The bottom line

Worth it for Semrush subscribers who need SEO-guided AI articles; overpriced as a standalone for casual bloggers.

What it really is

ContentShake AI — Semrush's SEO-driven AI content writing tool.

Our take

ContentShake AI (now rebranded inside Semrush as 'Content Toolkit') blends Semrush's keyword and competitor data with AI long-form writing. The plan costs $60/month with only a 7-day free trial and no permanent free tier. It is best understood as a Semrush add-on, not a standalone freemium product.

Why we rate it

Tight Semrush integration surfaces real search data during the writing process—a genuine edge over generic AI writers for SEO teams.

The catch

Only one plan tier; 5 articles/month is sparse and add-on packs are needed quickly. Little value without an active Semrush subscription.

Best for
Semrush subscribers needing AI-assisted blog writing
SEO teams optimizing content for Google rankings
Content managers who want keyword data embedded in the writing workflow
Not good for
Casual bloggers seeking a cheap or free AI writer
Non-Semrush users evaluating standalone tools
Social media or short-form copywriting use cases
Friction report
Time to value
Fast: connect Semrush account, enter a topic, generate a draft in minutes.
Scale breakpoint
Article add-on packs ($30 per 10 articles) add up quickly for teams publishing daily.
Walled garden
High: deeply embedded in Semrush; outputs are portable but workflow value is lost outside it.
