Cefra is a language-learning app for building and training your own vocabulary. This connector lets your assistant work with your private Cefra dictionary while you chat.
Ask it to turn a text, a lesson or a topic into a vocabulary set: it writes the translations, example sentences, articles and verb forms, and Cefra stores them in your account so you can train them on cefra.app. It can also search the curated Cefra catalogue, copy a ready-made set or word into your account, find words you already have, and tidy up sets.
You stay in control. You connect with your Cefra account on Cefra's own consent screen and choose the permissions: reading, adding and changing, and — only if you tick it — deleting. Deleting a set always takes a confirmation, deleted items can be restored through support for 30 days, and daily limits keep runaway edits in check. The connector only sees your vocabulary and the public catalogue: not your profile, your training progress or your conversation. Disconnect at any time under Connected apps in your Cefra profile.
Works with the language pairs of your Cefra account; add a new pair in the Cefra app first.
