Your child speaks the language at home but struggles with academic vocabulary. Koydo teaches math, science, and history IN their heritage language — so they learn both at once.
You see it happening. And it breaks your heart.
Academic vocabulary in the heritage language falls behind grade-level peers in the home country. They can chat with grandma but can't explain fractions.
They already speak it. Translation drills bore them. They need academic content, not “el gato es negro.”
Language is the bridge to culture. Losing it means losing connection to grandparents, traditions, and community.
CLIL (Content and Language Integrated Learning) is the method used by the world's best bilingual schools. Koydo brings it to your home.
Grade 1–12 subjects taught bilingually. Math in Spanish. Science in Mandarin. History in Arabic. Real academic content, not translation drills.
Koydo's AI adapts to your child's exact proficiency — harder vocabulary when ready, simpler when struggling. Every session is personalized.
See exactly what your child learned, their progress per subject and language, and where they need help. Full visibility, zero guesswork.
Spanish, French, Mandarin, Arabic, Hindi, Korean, Japanese, Portuguese, German, Italian, and 10 more. Full CLIL curriculum in every language.
Here's what your child's learning report looks like after 1 week.

Subject Progress
Real scenarios from families keeping their heritage language alive.
Learning Grade 3 science in Spanish. Vocabulary went from conversational to academic in 2 months. Now she can explain the solar system to her abuela.
Practicing math word problems in Mandarin. Now reads Chinese at grade level. His grandparents in Beijing can finally help with homework.
Learning phonics and counting in Arabic while preparing for Grade 1 in English. Both languages growing together, not competing.
Less than a single textbook for a full year of bilingual education.

Ages 3-18+, with content from pre-K through grade 12. Each level is adapted to the child's developmental stage and academic level, so a 5-year-old learning phonics and a 15-year-old studying chemistry both get age-appropriate content.
Yes! Koydo focuses on ACADEMIC vocabulary — the words your child needs for math, science, and history in their heritage language. Conversational fluency is great, but academic fluency is what keeps the language alive long-term and opens doors to university and careers in the home country.
Yes, the parent dashboard shows real-time progress per subject and language, vocabulary mastered, hours practiced, and CEFR-aligned proficiency tracking. You'll know exactly where your child stands and where they need extra support.
20 languages including Spanish, French, Mandarin, Arabic, Hindi, Korean, Japanese, Portuguese, German, Italian, Russian, Vietnamese, Turkish, Polish, Dutch, Swedish, Hebrew, Tagalog, and more. New languages are added regularly.
Koydo supplements, not replaces school. It provides the heritage-language academic content that most English-medium schools cannot offer — so your child stays on grade level in both languages without switching schools. Think of it as a bilingual after-school tutor that's always available.
