How to Import Existing Anki Decks into GemReader

November 12, 2026 · 4 min read

Consolidate your reading and spaced repetition in one quiet sanctuary. Learn how to import your existing Anki .apkg decks into GemReader and review them with modern FSRS-5 scheduling.

Why Bring Your Decks into GemReader?

Jumping between a book reader and an external flashcard application can fragment your attention. If you are learning a foreign language or studying for specialized licensing exams, reviewing vocabulary and concepts right alongside the books where you encounter them creates a cohesive daily routine.

GemReader allows you to import Anki packages (`.apkg`, `.colpkg`) and text exports directly into its local study engine. Both standard two-sided cards and cloze deletions transition smoothly, taking full advantage of GemReader's clean typography and modern FSRS-5 spaced repetition scheduler.

What You'll Need

Before importing an external deck, ensure you have:

• **Platforms**: GemReader installed on your device (Android or iOS). • **Prerequisites**: An Anki deck file (`.apkg`, `.colpkg`, or `.txt`/`.csv`/`.tsv` export) saved on your device. • **Connection**: 100% offline (the import runs entirely on your phone).

Step-by-Step Instructions

1. Open GemReader and tap the **Study** icon in the bottom navigation bar. 2. Tap the options menu in the study header and select **Import Anki deck**. 3. Your device's file picker will open. Browse to your files and select your `.apkg`, `.colpkg`, or text export file. 4. GemReader inspects and extracts the cards on device, deduplicating any entries that already exist in your deck. 5. Once complete, a confirmation reports **Deck imported** with the count of added cards. 6. The imported cards appear on your **Study** screen immediately, scheduled and ready for review.

Helpful Tips & Common Questions (Librarian's Advice)

• **Supported File Formats**: GemReader supports `.apkg`, `.colpkg`, and Anki plain-text (`.txt`, `.csv`, `.tsv`) exports. If an `.apkg` was generated by a very new Anki build and fails to read, exporting as plain text or an older deck format ensures compatibility. • **Preserved Cloze Syntax**: Cloze blanks and deletion fields are preserved during import, allowing you to review fill-in-the-blank cards seamlessly. • **Duplicate Protection**: If you re-import an updated version of a shared deck, GemReader automatically skips duplicate cards to protect your review history.
