## What it is
EchoFlow is a self-hosted web application for sentence-by-sentence audio reading and shadowing practice. Users import their own mp3 audio and matching lrc subtitle files, which are stored locally in the browser (IndexedDB) and played back with click-to-play, continuous playback, looping, and speed controls.

## Use cases
- practice English listening by clicking individual sentences in textbook audio
- import my own mp3 and lrc files to make interactive read-along lessons
- shadow and repeat sentences from language learning audio
- play audio lessons with EN / EN+CN / CN subtitle display modes
- self-host a point-and-read audio player with Docker
- track learning progress and resume playback where I left off

## When to choose
- you have legally owned mp3+lrc textbook audio and want sentence-level playback
- you want a free, ad-free, self-hosted tool with no content uploads
- you need PWA/mobile support and offline local storage of your audio

## When to avoid
- you expect built-in textbook audio or content — none is provided
- you need automatic speech-to-text or subtitle generation
- you want cloud sync of your learning data across devices

## Facets
