Why AI web apps give businesses an advantage
Standard web apps store and display information. AI web apps go further: they understand questions, summarise documents, generate content and suggest next steps. That makes them far more useful to the people who rely on them every day, inside and outside your business.
AI web apps cut manual work, improve decisions and deliver better customer experiences. Because they run in the browser, they're easy to access, update and turn into a PWA.
