About Runo
Runo is the world's first AI-native, age-adaptive dictionary and word companion for children. Available now for free in English across the web, iOS and Android, Runo is your child's learning friend with one clear goal: to improve literacy, rapidly.
The Parent's Dilemma, Solved.
Have you ever struggled to explain a complex word to your child in a way they actually understand? Do you worry if they'll truly recall those words a week later?
Runo bridges the gap between static definitions and real-world understanding. Developed by a software engineer and an applied linguist, Runo combines authoritative dictionary definitions with GenAI to create a tailored learning experience. Whether your child is 5 or 15, Runo adapts its explanations to their developmental stage – making vocabulary feel like a discovery, not a chore.
Beyond the Definition
Runo is more than a search bar; it's a recall engine. The app stores every word your child explores, allowing our linguistic logic to craft personalized lesson plans, stories, and visual aids. These tools are scientifically designed to move words from short-term curiosity to long-term mastery.
Safety Isn't a Feature—It's Our Foundation.
We believe LLMs are the future of education, but on their own, they aren't built for kids. That's why Runo is built with a "Hard-Scoped" architecture.
While general AI can wander into mature topics, Runo is strictly constrained to vocabulary and literacy. Our multi-layer safety guardrails monitor every interaction behind the scenes. If a request falls outside our educational scope, Runo simply won't respond. This deterministic safety ensures your child stays in a protected learning "sandbox" at all times.
Our Commitment
We are committed to making Runo work for all children, showing how powerful AI can be when it is focused, disciplined, and dedicated to education.
Give your child a limitless vocabulary. Start your journey with Runo today.
