Two-Way Sync (Pro Tier)
Pro tier supports Anki Web real-time two-way sync:
- Words you learn in LangKey auto-push to Anki Web
- Reviews done on Anki Web also write back to LangKey SRS
- Solves the "review the same words in two apps" pain
Notes
- Anki templates (card front/back layout) are not imported — LangKey uses its own display style
- Anki's review algorithm (FSRS / SM-2) is converted to LangKey's SM-2 implementation
- Large files (> 5000 words) recommend batch import
