Lucida AI

Lucida AI develops AI-powered, voice-first language learning and speaking coaching through real-time speech interactions, serving both individual learners and global enterprises. The company's proprietary speech-to-speech technology is deployed to corporate clients via a closed Large Language Model that processes natural conversations while ensuring end-to-end encryption.

At the centre sits Lucy, the flagship AI tutor, which delivers ultra-realistic, low-latency speech interactions and analyses pronunciation, grammar, vocabulary and fluency in real time, returning instant feedback. The technical work spans speech recognition and pronunciation analysis, natural language processing, Large Language Models, real-time voice AI, and the AI/ML infrastructure required to sustain millions of daily spoken minutes.

Its scale is considerable. The consumer platform has surpassed 10 million downloads, holds a 4.8 App Store rating and has generated over 3 billion minutes of spoken practice across 150+ countries. It has been named App of the Year and ranks among the top education apps in multiple markets.

The company has raised $6.7 million and builds its AI infrastructure and proprietary technology in-house, operating across both consumer and enterprise markets with a focus on measurable learning outcomes.
