Install the desktop app

The desktop app gives you the full Libre Academy: every language runtime, the ingest pipeline that turns books into courses, and the local AI tutor.

Install

Grab the latest build from GitHub Releases. Pick the bundle for your OS:

macOS: .dmg (Apple Silicon + Intel universal)
Windows: .msi
Linux: .AppImage or .deb

First launch

Libre Academy unpacks the bundled starter packs into your data dir and opens the Library. Pick a course, start the first lesson, and the sidebar populates with the chapter tree.

What’s inside

PDF / EPUB ingest: drop any technical book in, get a Claude-structured course out
Docs-site crawler: point at a documentation URL, generate a course from the structure
Challenge pack generator: synthesize 20-200 exercises in any language, with a slider for cost
Native toolchain runners: C, C++, Java, Kotlin, C#, Swift, Assembly all execute via subprocess shells
Local AI tutor: Ollama-backed, so the floating fish character knows your lesson context and never sends a token to anyone else’s server

Optional cloud sync

Libre Academy offers a free, optional cloud sync to mirror your progress, XP, and streak across machines. It’s off by default, so you opt in via Settings → Sign in. The sync server stores only the small JSON-shaped progress record; lesson contents stay on disk.

The desktop app is free and open source (MIT). There is no paid tier.
