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

Feedback

Report import compatibility issues on GitHub Issues, attach a sample file.

SRS Spaced Repetition

Wrong words auto-enter the SM-2 spaced repetition queue, pushed precisely by algorithm — LangKey's core differentiator from immersive translators.
