Sparky AI is a mobile-first English speaking coach that uses GPT-4 and on-device speech models to help learners practise fluency, pronunciation, and real-world conversation — guided drills, scenario role-plays, and instant feedback. Native iOS and Android only; no web version.
English learners need private, judgement-free speaking practice but struggle to find patient conversation partners or afford 1:1 tutoring. Text-based apps don't build speaking fluency.
A GPT-4 powered mobile coach that simulates real conversations, scores pronunciation in real time, adapts difficulty to the learner's level, and covers travel, job-interview, small-talk, and workplace scenarios.
“CodeLamda shipped a polished cross-platform speaking app with GPT-4 in the loop, real-time pronunciation scoring, and clean native UX on both stores.”
