Writesonic and Contentpen both track how your brand shows up in AI search. Contentpen also writes, optimizes, and publishes the content that improves it, and tracks more AI engines at every price. Here's how they compare.
SEO research and planning
Keyword research, topical clustering, and live SERP analysis shape every article. You can set a target AI prompt so content is written to be cited by answer engines from day one.
End-to-end content workflow
Research, writing, combined SEO and GEO scoring, internal and external linking, branded images, and publishing to 6 CMS platforms all happen in one place. Articles go from keyword to published without leaving Contentpen.
Performance analytics and opportunities
Six SEO Opportunities detectors show where your next traffic is hiding. AI Visibility tracks you across up to 7 AI engines, including Perplexity, Copilot, Claude, and Grok, on self-serve plans.
Automation and scaling
Autopilot tracks, plans, writes, and publishes on a schedule, with approval controls. Bulk-create up to 100 articles from a CSV and bulk-publish them in one step.
SEO assistance
Provides optimization features and integrations, though advanced research may require additional tools.
AI content generation
An AI article writer and SEO agent create 15 to 50 articles a month. Content optimization is listed for Enterprise only, and publishing integrates with WordPress.
Daily AI visibility monitoring
Daily AI visibility tracking across ChatGPT, Gemini, and Google AI Overviews on self-serve plans. The other 7 engines, including Perplexity, Claude, and Copilot, require Enterprise.
Agentic workflows and Action Center
Agentic workflows and the Action Center automate visibility fixes. Self-serve plans get trial runs, and full access is on Enterprise.

Writesonic and Contentpen both track AI search visibility and create content, but they weight those jobs differently. Writesonic leads with monitoring, and Contentpen leads with the content that changes what AI engines say about you.
Writesonic's self-serve plans track three AI experiences: ChatGPT, Gemini, and Google AI Overviews. Perplexity, Claude, Copilot, and Grok are all Enterprise-only. Contentpen tracks 4 engines on its $79 plan, 5 on Scale, and all 7 on Agency, so you see where buyers actually ask without a sales call.
Visibility data only matters if you act on it. Writesonic's $79 plan includes 15 articles, and full content optimization is listed for Enterprise. Contentpen's $79 plan includes 40 articles with SEO and GEO scoring, branded images, and one-click fixes. Every piece can target the exact AI prompt you want to be cited for, then publish to your CMS.
Writesonic's $199 plan includes 2 users and 1 project, and ongoing agency client projects start at $150 each per month. Contentpen's $199 plan includes 10 users and 5 workspaces. Agency gives you unlimited users and 10 workspaces, and each extra client workspace costs $39 with articles, image credits, and prompts included.
Contentpen's Autopilot plans topics from your keyword and search data, writes them in your brand voice, and publishes on schedule, with approval controls for new articles and refreshes set separately. Six Opportunities detectors keep feeding it pages worth refreshing, so visibility and traffic keep improving without new manual work.
