Association of Software Professionals

Our company (AI Internet Solutions LLC) was established in 1997 to develop and market CSS HTML Validator (formerly CSE HTML Validator), an award-winning, popular and powerful HTML, XHTML, CSS, JavaScript, SEO, link, spelling and accessibility checker for Windows that helps webmasters, governments, businesses, Internet professionals, educators, and students produce quality web documents. Since 1997, we've listened to our customers and provided great customer service and great products such as CSS HTML Validator in multiple editions.

We continue to actively develop CSS HTML Validator so that it stays up-to-date and continues to be an exceptional all-in-one HTML, XHTML, CSS, JavaScript, SEO, link, spelling, and accessibility checker for the Windows platform. For example, recent updates and major releases continually offer improved and updated HTML5 and CSS3 support as those standards continue to evolve.

Because CSS HTML Validator is also useful and helpful to anyone learning web development, we'll continue our efforts to penetrate the educational market by providing special offers and discounts to educational institutions and students. Finally, we plan to continue to help make the web development community aware of CSS HTML Validator and the importance and benefits of properly constructed and accessible web documents.
