About Fluently

The company behind your AI language tutor

Fluently builds an AI private-tutor experience for language learning through natural voice conversations and real-time feedback on pronunciation, grammar, phrasing and more.

Speaking is the most difficult and underserved part of language learning, so we focus on people who have studied a language for years and understand it well but still cannot speak confidently in real conversations.

The company was started in 2023 by two ML engineers who lived that problem themselves — and its app has since passed a million downloads across more than 160 countries.

What we build

Fluently is a voice-first AI language tutor for iOS and Android. You hold a real conversation — a free topic, a work scenario or a mock interview — and after each answer the app shows what to fix: pronunciation down to individual sounds, grammar, vocabulary, and how a native speaker would have phrased the same thought.

Your level is scored across pronunciation, fluency, vocabulary, grammar and comprehension, and daily speaking practice targets the weakest area.

Fluently teaches 13 languages: English, Spanish, French, German, Italian, Portuguese, Polish, Russian, Korean, Hebrew, Arabic, Chinese and Japanese. The interface is available in English, Japanese, Portuguese, Spanish and Korean.
