SEO Writing AI is a web-based tool for creating SEO-focused articles, blog posts, and affiliate content. It offers formats such as product roundups and reviews, how-to guides, news articles, lists, and landing pages, and says it analyzes search results in real time to shape content for search and AI answers. It supports more than 50 languages and includes brand voice controls. The maker says the tool uses models from OpenAI, Anthropic, Google, and DeepSeek, alongside proprietary AI technology for specific tasks. Most models use one credit per article; advanced OpenAI and Anthropic models use four, while the most powerful Anthropic model uses ten. WordPress connections support publishing or scheduling, including batches of up to 100 articles. The pricing page also lists a Shopify app and a WordPress MCP Server for connecting Claude to WordPress. For affiliate work, its Amazon product-list feature uses product URLs and ASINs to generate product details, pros, cons, and descriptions. The free plan provides three articles and a 25,000-word limit without requiring payment details. Paid plans start at $19 a month.
