Where your cards' facts come from: sources and citations in Encodr

Any flashcard can assert anything. "The answer is X" looks exactly as confident whether it's backed by a textbook or by someone's half-remembered guess, and once a card is in front of you mid-review, there's no way to tell the difference - unless the deck tells you where it came from.

How it works

Every class carries one numbered bibliography, built by whoever created the deck. Individual cards can cite specific entries from it, and those citations show up as small numbered chips - [4], [6] - right in the reveal area when you flip a card, in Session, in the Feed, and in Learn mode. Tapping a chip jumps straight to the Sources screen and the exact entry, not a generic "sources" page you have to search through.

Why this is better than a deck just seeming trustworthy

A polished-looking deck and a well-sourced one aren't the same thing, and there's usually no way to tell them apart from the outside. Explicit per-card citations turn "this seems right" into something you can actually check - which entry, which source, right there on the card that made the claim. For curated classes, the entries can carry a "Verified by AI" badge, meaning a connected AI cross-checked the card against real source material rather than the source list existing for show.

What it isn't

Encodr doesn't fetch or parse documents itself - there's no in-app file upload for this. Verification happens through a connected AI that has access to the real material and adds sources and citations directly, the same way connecting an AI to build your decks works for card creation. The bibliography is a record of what a card is based on, not an automated fact-checker running in the background - it's only as good as whoever built the deck made it, which is exactly why it's visible instead of hidden.
