Pros & Cons
ContentShake AI
- Content generation is grounded in Semrush’s own keyword and SERP research data
- Convenient for teams already working within the Semrush ecosystem
- Paid add-on cost (~$60/month) on top of an existing Semrush subscription, not included in any base plan
- Only 5 AI-generated articles per month at the base add-on price — low volume for heavier content needs
- Recently rebranded (August 2026) as the AI Article Generator within Content Toolkit, causing some naming confusion
ChatGPT
- Largest user base and ecosystem of any AI assistant, with the most third-party integrations
- Genuinely broad capability across writing, coding, research, and file analysis
- Custom GPTs allow tailoring the assistant to specific repeated tasks
- Frequent model updates keep it competitive on raw capability
- Free tier has usage limits and access to a lower-tier model than paid plans
- Can produce confident-sounding but incorrect information, especially without browsing enabled
- Breadth can mean less depth than a tool purpose-built for one specific workflow
- Data usage and training policies require attention for sensitive or regulated work
