How Elly inspired Helli

Helli was born out of personal necessity. When co-founder's 2-year-old daughter Elly was diagnosed with autism spectrum disorder and non-verbalism, they faced a painfully simple question: how can a child communicate if they don't speak? Expensive and complex aids were not accessible to the family – so they decided to create something themselves.

They started with a simple solution where Elly could choose between four pictures – eat, drink, sleep, or go to the potty. This changed everyday life. They saw how even a small opportunity to express herself gave Elly more independence and joy. Development continued, and today the Helli application contains over 800 words, AI-based language support, and personal customization. Elly uses it daily, and specialists have noticed significant progress in her development.

Helli is more than technology – it's an opportunity to hear those who haven't been heard before.
