# Erla — AI-powered language practice app
> Erla is a mobile language-learning app that helps people practice 22 languages through listening, reading, short videos, AI chat, and voice conversations. It is built on the comprehensible input method (Stephen Krashen's i+1 hypothesis): learners acquire language by understanding meaningful messages, not by drilling flashcards or memorizing grammar rules. Available on iOS and Android.
## Markdown editions
Every page on this site has a clean Markdown edition at the same URL with a `.md`
extension — no navigation, no markup, roughly a tenth of the tokens. Each HTML page
links to its own with `<link rel="alternate" type="text/markdown">`.
- `https://erla.app/learn/spanish` → `https://erla.app/learn/spanish.md`
- The homepage is at https://erla.app/index.md
- Localized pages follow the same rule: `https://erla.app/de/learn/spanish.md`
- [Every English page in one file](https://erla.app/llms-full.txt): the whole site concatenated, for agents that would rather make one request than forty.
