For parents seeking innovative ways to blend language learning with real-world exploration, Dex offers a fresh alternative to traditional screen-based education. This AI-powered camera device encourages children to interact with their surroundings while picking up new vocabulary in multiple languages, merging curiosity with practical skill development.
Three concerned parents, Reni Cao, Xiao Zhang, and Susan Rosenthal, decided to tackle excessive screen time by creating a tool that promotes active engagement. Leaving behind careers in technology, they developed Dex, a gadget that recently attracted $4.8 million in funding from investors impressed by its unique approach.
Resembling a high-tech magnifying glass, Dex features a camera on one end and a touchscreen on the other. Children simply point it at objects, and the built-in artificial intelligence identifies the item, displaying and pronouncing its name in the language of their choice. Beyond simple translation, the device includes interactive story lessons and educational games, setting it apart from app-only options like Duolingo Kids.
“Our goal is to deliver authentic language learning through real-world interaction,” Cao explained in an interview. “Kids aren’t just passively listening, they’re thinking, creating, and exploring. They learn by doing, which makes the experience far more meaningful.”
Aimed at children between three and eight years old, Dex currently supports eight major languages: Chinese, French, German, Hindi, Italian, Japanese, Korean, and Spanish. It also accommodates 34 regional dialects, including Egyptian Arabic and Mexican Spanish, offering nuanced linguistic exposure.
The device’s story mode prompts kids to participate actively, encouraging them to respond to characters using their new language skills. A companion app lets parents monitor progress, tracking learned words, completed stories, and daily usage streaks.
An upcoming feature will enable children to converse with an AI chatbot, though the company acknowledges this tool is still in testing and may give some parents pause. To ease concerns, Dex has implemented rigid safety protocols, including real-time monitoring and filtered responses to block inappropriate topics.
During testing, the AI correctly avoided sensitive subjects like nudity, though it did recognize and translate the word “gun”, a detail the team is addressing with customizable parental controls to filter specific terms. The company also emphasizes its zero data retention policy, ensuring no images or conversations are stored.
Dex is pursuing COPPA certification to comply with child privacy laws, reinforcing its commitment to safety. Backed by investors like Pinterest co-founder Ben Silbermann and former OpenAI safety lead Lillian Weng, the device is priced at $250. While not inexpensive, the founders position it as a cost-effective option compared to private tutors or immersion programs, with hundreds of families already adopting the technology.
