As answered by people managing Project Euler and AccessGuard.
AccessGuard's answer:
I'd leave this one for you to answer personally - it's more authentic coming from the founder. Something about why you started building it.
AccessGuard's answer:
uby on Rails, PostgreSQL, headless Chrome for JavaScript rendering, and Anthropic's Claude AI for generating fix suggestions.
AccessGuard's answer:
AccessGuard combines automated WCAG scanning with AI-powered fix suggestions. Instead of just listing issues, it tells you exactly how to fix each one with code-level guidance
AccessGuard's answer:
Small to mid-size businesses, web developers, and agencies who need to make their websites WCAG compliant - especially those concerned about ADA lawsuit risk but who don't have a dedicated accessibility team.
AccessGuard's answer:
Most accessibility tools either give you a list of problems with no fixes (WAVE) or cost thousands per year (Siteimprove). AccessGuard gives you both the scan and AI-generated fix suggestions at a fraction of the price, with a free tier to get started.
AccessGuard's answer:
Skip this one if you don't have notable customers yet - better to leave it blank than make something up.
