Built to be played by everyone.

• Semantic HTML and ARIA labels so screen readers can describe the interface.
• Full keyboard navigation for menus and links, with visible focus styles.
• Voice support: in chess you can speak your moves, and every lesson has a Listen button that reads the content aloud.
• Responsive layouts that work from small phones to large desktops.
• Color choices chosen for readable contrast, and no flashing or strobing content.

How to play each part of the site with the keyboard, a screen reader or voice is in the accessibility guide.

I'm working toward the WCAG 2.1 Level AA guidelines as a target. Cognivo isn't formally certified against them, and some areas don't fully meet that bar yet — I treat it as a direction, not a finished checkbox.

• The interactive game boards rely on pointer/drag interactions that can be awkward with some assistive technology; keyboard and voice paths are still being improved.
• Voice features depend on your browser's built-in speech support, so they aren't available everywhere.
• This is an independent, solo-built project, so fixes ship as I get to them — your reports help me prioritize.

If something is hard or impossible to use, please tell me and I'll work to fix it. Email support@cognivo.digital with the page and what went wrong, and I'll follow up.
