How it works

Talk.Credolay notices.Your plan changes.

One short exchange, one small fix, and a lesson built from it.

01

You talk

With a coach, or act out a real situation: a café, a job interview, the doctor.

02

Credolay notices

How long you wait, how fast you speak, where you slow down. One fix per turn, never a lecture.

03

Your plan changes

A three-minute lesson and a recall queue, built from your own mistakes. The level moves with you.

☕ Ordering at a café
Spanish · your coach, Lucía
level 2 / 5
¿Qué le pongo?
What can I get you?
Quiero un café con leche, por favor… y un… croissant?
…y una medialuna, por favor.
One small fix. That is all the coach corrects per turn.
¡Perfecto! ¿Para tomar aquí o para llevar?
2.4s wait
What Credolay noticed: you paused before food words. Next lesson: ten café words, three minutes. The coach will bring them up again tomorrow.
Why it works

Four things we know about memory.Four rooms built on them.

Speak01
You
Quiero un… café con leche?
Coach
Nearly. Say: un café con leche, por favor.
One fix. Then the conversation goes on.

Knowing is not saying

Knowing a rule and saying it without thinking are different skills. Speak trains the one that lags.

Rules become habits with practice
Recall02
You
the bill → …la cuenta!
Recall
1.8s. Faster than last time.
Comes back in 3 days, just before you forget.

Remembering beats re-reading

Reaching for a word makes it stick. Words come back just before you would forget them.

Testing yourself, spaced out
Learn03
You
Yesterday: you paused before food words.
Learn
Today: 10 café words, 3 minutes.
Built from your own last conversation.

Effort is the signal

When it gets too hard, you slow down. Lessons stay small and the level eases before you fail.

You can hold about four things in mind at once
Translate & Lens04
You
📷 A menu. What is a medialuna?
Lens
A croissant. Say: una medialuna, por favor.
The word stays with the café, so it comes back there.

Words stick to situations

A word learnt on a real menu comes back when you need it. Photograph it, get what to say.

Memory keeps the context with the word
