It is a layer on top of SEO, not a replacement. - **SEO citation share** is measured by how often LLMs cite a given domain when answering relevant prompts, expressed as a percentage of citations across competitor domains. - **Klyna's engine runs locally**, with zero paid-API dependencies. Customer data never leaves the customer's server, browser, or controlled infrastructure. - **Klyna's free tier does real work**, not demo-only work. Paid tiers earn their keep with automation and scale. ## About - [About Klyna](https://klyna.dev/about) - [Blog](https://klyna.dev/blog) - [RSS Feed](https://klyna.dev/rss.xml) - [GitHub](https://github.com/klynahq) -
