How it works

From what you need to say to a better sentence. In one conversation.

No course to enrol in, no twelve-week plan. You bring your own situation, you leave with a better sentence, and you know what changed. A few days later it comes back — so you can say it on your own.

Topic

Start with your own situation — or a sentence from last time.

Say what you want to talk about today. Out of ideas? Your AI coach picks up where you left off and suggests a topic — change it with one tap.

Conversation

Talk out loud. Or type.

Your AI coach speaks first. You reply, the timer runs. The transcript, suggestions and phrases you’ve saved open full screen — without breaking off the conversation. Rather type? Have the same conversation in text.

Afterwards

See better versions of your sentences.

After the conversation you see better versions of your sentences and one recommended exercise. One tap sends the phrases you want to keep to your flashcards, ready for review.

Coming back

The sentence comes back on its review day.

You don’t have to remember to review. The calendar shows what’s up for review today, and you can reorder or remove the steps in your learning plan. This is how we count progress: when you next say it yourself, unprompted. The “Used again” screen that will show it is being built.

Your first conversation

What you’ll see in your first conversation.

1
Free, no card needed
The app is free, and you create an account without a card. You start with a real situation, not a placement test; in the latest version, after your first feedback you can take a short level check (about 3 minutes) — or skip it.
2
Pick your AI coach
Four AI coaches — openly AI — and four ways of running a conversation. You choose who to talk to, not which lesson to do.
3
Your first conversation
Talk about what’s on your mind. Your AI coach leads, asks follow-up questions, and doesn’t stop you mid-sentence to correct you.
4
Your first better version
Afterwards, you see your sentences next to better versions — and why they’re better.

That’s enough to tell whether it’s for you. The library, the tools and your reviews come later, built on what the conversation showed.

Say → See → Fix → Keep → Use again

These steps have a name: the FizzUp Loop.

1
Say
You talk about what’s on your mind.
2
See
You see what you said — and what you meant to say.
3
Fix
A correction that fits the moment: a better version, a nudge to find it yourself, or — for now — nothing. And you always know why.
4
Keep
The phrases that matter come back on their review day.
5
Use again
Days later, in a new conversation, you say it yourself.
