    With a coach, or act out a real situation: a café, a job interview, the doctor.
  2. 02Get one fix
    The coach corrects one thing per turn, never a lecture.
  3. 03Practise what slipped
    A three-minute lesson and a recall queue, built from your own mistakes.

¿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?

What Credolay noticed: you paused before food words. Next lesson: ten café words, three minutes. The coach will bring them up again tomorrow.

Progress

Why it works

Four things we know about memory that most apps ignore.

01

Effort is the signal

When it gets too hard, you slow down. Credolay eases the level before you fail.

You can hold about four things in mind at once
02

Remembering beats re-reading

Reaching for a word makes it stick more than reading it again. Recall runs with the clock on.

Testing yourself works better than studying
03

Forget on schedule

Words come back just before you would forget them. The gaps grow as they hold.

Spaced practice
04

Knowing is not saying

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

Rules become habits with practice
How it works

Talk. Credolay notices. Your plan changes.

01

You talk

02

Credolay notices

How long you wait, how fast you speak, where you get corrected.

FAQ

Questions

Which languages?+

English, French, Spanish, German, Portuguese, Italian, Japanese, Mandarin, Arabic and Dutch, from any of the same ten.

Do I need a microphone?+

It is best with one, because speaking is what the coach learns most from. You can type every reply instead.

What does it measure?+

How long you take to start, how long you speak, pauses, corrections, how fast you remember and how sure you feel. Nothing about your body.

What is the Brain Profile?+

Five short tests in Credolay Pro, eight minutes in all: memory, speed, new sounds, focus and learning new words. A rough measure to shape your plan, not a medical test.

Is it free?+

Yes. Pro adds the Brain Profile and the plan shaped by it.

Say hello. That is the whole first lesson.
