Museful is a social impact startup transforming cultural accessibility through our AI tour guide technology. Based in Cottbus, Germany, we empower museum visitors of all backgrounds with personalized, multilingual guides that adapt to individual interests and knowledge levels. By simply using their smartphones, visitors can engage with exhibits in their preferred language and learning style. We prioritize serving smaller, under-resourced museums, helping them digitally transform despite limited budgets. Aligned with SDGs for education and equality, Museful bridges the digital divide in cultural access, ensuring museums remain vibrant, inclusive spaces where everyone can connect meaningfully with cultural heritage.
