Most AI website audit tools focus on SEO or performance. Why is UX still mostly manual?

After reviewing a lot of SaaS landing pages, one thing keeps standing out.

Most website audit tools do a good job covering:

• SEO
• Performance
• Accessibility
• Technical issues

But when it comes to UX and conversion, the feedback is usually very limited.

Questions like:

• Is the CTA clear enough?
• Is the visual hierarchy guiding users correctly?
• Are trust signals missing?
• Is the onboarding confusing?
• Does the page create unnecessary friction?
• Which UX issues actually hurt conversions the most?

Those still seem to require a manual review.

That got me interested in AI-powered UX analysis, so I started exploring a tool that generates a structured UX report from a website or screenshot.

It looks at areas like:

• UX Audit
• UI Audit
• Landing Page Audit
• Conversion Optimization (CRO)
• Visual Hierarchy
• CTA Analysis
• Navigation
• Trust Signals
• Mobile UX
• Accessibility
• User Flow
• Prioritized recommendations

I'm looking for honest feedback from other founders before taking it further.

• What do you think current website audit tools are missing?
• Would AI-generated UX audits actually save you time?
• Which parts of a UX review still need a human?
