Free audiobooks with synchronized text for language learning
Clean audiobook+text sync for language learning, but LibriVox and LingQ already do this.

Syncing audiobooks with highlighted text and instant translations is the product's clear hook and will click for people who learn by listening. The landing shows tidy language buckets, cover art cards and an 'install the app' flow, but the page reads like an MVP — impressive alignment work is implied, yet there are no obvious study features (flashcards, clip replay, speed controls) or pricing/usage details on the surface.
