Glisker

Most landing page tools give you a long checklist of best practices. Glisker does the opposite — it tells you what a first-time visitor actually understands in five seconds, then picks the single most important thing to fix, not twenty. You drop in a screenshot and get read across five things: clarity, relevance, trust, action, and focus. It's grounded in what's really on your page, so the feedback is specific, not generic advice. No signup. Nothing stored. Free to try in about ten seconds.
