Core Features

Koala Cards has three main areas: review, writing, and reader. They are designed to work together in a normal day-to-day study routine.

Card Review

Deck sessions mix due cards, new cards, and remedial cards. Speaking answers are recorded and graded, and you can score difficulty with AGAIN / HARD / GOOD / EASY.

  • Pause, archive, edit, or skip cards mid-session
  • Hotkeys for grading, recording, playback, and card actions
  • Study Assistant can explain and propose card edits

Writing Practice

Practice in typing or speaking mode, then get corrected text and concise feedback. Click unknown words to define them in context and create cards directly from those words.

Write your response, review corrections, then select unknown words to create new cards.

Reader and Highlights

Save an article URL or paste raw text. Highlight phrases to generate term definitions, general meaning, and meaning in context. Import those highlights to your deck in one click or in bulk.

  • Unread/read library workflow with ingest status tracking
  • Article-level typing practice mode for comprehension
  • Instapaper integration
