Practising with Ren when nobody else is around

The hard part of learning a language by using it is finding somebody to use it with at eleven at night. Ren is who is there then.

Who she is

Ren is an AI, labelled as one everywhere her name appears. She writes only in the language you are studying, one or two sentences at a time, and asks you something back so there is always somewhere for the conversation to go.

She does not correct you and she does not explain words. The room already does both, separately, and doing it twice in one breath makes a conversation into an exercise.

She speaks at your level

How well you write the language is worked out from what you have already written, not from a form you fill in. A beginner gets short sentences and the most common words. Somebody comfortable gets normal speech, idiom included.

There is nothing to set. It follows what you write, so it moves as you do.

She revises with you

Words you saved and are closest to forgetting are handed to her, and she works one or two into what she was going to say anyway. You meet them in a sentence somebody is saying to you rather than on a flashcard.

If none of them fit what the conversation is about, she uses none. A word forced into a sentence teaches less than a natural one.

Starting with her

Choose Learn on the front page, say which language you want to practise, and she is there when the room opens. She needs an email. No password, just a link sent to it.

Chat is the other half, and she is not in it: a room you share with people is for the people in it.
