## What it is
Hashcards is a plain text-based spaced repetition system written in Rust. Flashcards are stored as Markdown files with a lightweight Q/A and cloze notation, and reviews are scheduled using the FSRS algorithm.

## Use cases
- memorize facts with flashcards from plain text files
- review cloze deletion cards stored in markdown
- track flashcard decks in git
- replace Anki with a simple text-based SRS
- drill flashcards from the terminal

## When to choose
- you want flashcards as plain text files editable in any editor and version-controlled
- you prefer a minimal terminal workflow over GUI apps like Anki
- you want FSRS-based efficient scheduling with simple front-back and cloze cards

## When to avoid
- you need rich card types, images, audio, or Anki-style note templates
- you want a graphical interface or mobile app with sync
- you need shared decks or add-on ecosystems
