About Semji

Semji is an agentic AI platform from Semji SAS in Lyon, France, that optimises content for both AI search and Google and prioritises work by revenue impact. Its Intelligence Hub tracks AI visibility across six engines, including ChatGPT, Google AI Overviews, Perplexity, Gemini, Claude and DeepSeek, and turns an opportunity into a brief in one click. Brand Voice and a Knowledge Base teach its agents a company's tone and product facts before they write. A Content Score rises as SEO, readability and brand rules are met, and a CMS Publisher sends finished drafts to WordPress, Drupal, Magento, Contentful or Strapi. Semji says more than 500 companies use it. Pricing is quote-based.

๐Ÿ† Pros & Cons 3.9/5

Semji is built for content teams that need to keep a brand's voice and facts consistent while optimising for Google and AI answers. Its agents propose changes that people review first. It is sold by quote to larger companies, so it is not a fit for small budgets.
