Our own product: Ɛfie

Sibyl Systems builds software for clients. We also build our own. Ɛfie is an African heritage language app for the diaspora: native-speaker audio, spaced repetition, AI pronunciation feedback for learners. Twi is live, and Yorùbá content is recorded and in development. It runs on Flutter and Firebase, with subscriptions through RevenueCat.
Native-speaker audio

Core lessons voiced by native Twi and Yorùbá speakers, never generic narration.

AI voice practice

Real-time pronunciation feedback, so learners are understood by native speakers.

Spaced repetition

Adaptive review scheduling reinforces vocabulary and phrases over time, measured on completed reviews.

Three screens from the Ɛfie app: a Twi phrase card with tone marks, a lesson journey, and a learner's progress
