# AI Web Center > Plain-language guides, a glossary and comparison tables for developers and business owners adopting AI, especially AI-assisted programming. Written by Jan Dekkers. Every claim about a tool links to the vendor's official documentation and shows the date it was checked. AI Web Center is an independent learning hub. It doesn't sell AI tools and isn't sponsored by any vendor. Content is written in plain language with the direct answer first. ## Guides - [What Is an MCP Server?
