Discover content

Discover is where you find new lesson sets across the whole library and download them. It lives as the Discover tab inside the Content hub (/content); the older /discover link still works and redirects there.

The split is deliberate: My content shows only what you have already downloaded, while Discover is the catalog you browse and pull from. That keeps your day-to-day learning surface free of sets you have not chosen yet.

Search index

Discover is backed by a search index over the catalog. Typing filters instantly across set titles, descriptions, domains, lesson titles, card fronts and backs, and tags. The search is tolerant of case and accents and understands German digraphs (ae/oe/ue/ss). The index is built lazily on first interaction — no backend call, it works in both storage modes.

Downloading a set

Each result carries a Download action. Downloading copies the set into your local cache (IndexedDB in browser-only mode, the filesystem cache in server mode), after which it appears under My content and Continue Learning and can be played offline.

Every set shows a source badge — Official / Bundled, your own connected repo, or Officially recommended. A source filter narrows the catalog to a single source. See Multiple content repositories for connecting and managing your own sources.

Import tab

The Content hub also exposes an Import tab for bringing in a chat export or a single lesson file. Old /import links redirect into it.
