How does the free plan differ from Premium?

Free gives you 100 words and limited audio. Premium unlocks the full ~6,000-word dictionary, all audio stories, CEFR filtering, and a 7-day trial.

Can I create my own vocabulary lists?

Yes. You can build and share custom sets using words from the official dictionary or the community.

How does the SRS algorithm work in LangDeck?

It's an adaptive system that schedules reviews just before you're likely to forget a word. Performance varies per card, with harder words shown more frequently.

What is the source of the dictionary words and examples?

All entries come from a moderated, official dictionary maintained by LangDeck, ensuring verified translations. Users can suggest new words via an AI assistant for manual review.

Is there a way to integrate LangDeck with other AI tools like ChatGPT?

The methodology section provides specific prompt templates to generate practice texts or conversations, which you can then feed new vocabulary back into LangDeck sets.
