Describe it. Watch it get built.
Tell Kalle what you need in a message. It plans the pages and data, writes the code, tests it in a real browser and puts it live.
From one message to a working app
Pick an idea. Kalle asks what it needs to know, builds it step by step and tests it before it goes live.
Say it the way you would to a person
No special commands. Describe the result you want, and Kalle works out the pages, data and code behind it.
It asks before it guesses
When a choice changes what gets built, Kalle asks. Your answer goes straight into the plan.
Show it, don't just describe it
Drop files or links into the chat. Kalle reads them and uses them as the starting point.
Every step, in plain words or in code
Follow along in everyday language. Switch to technical when you or a developer want the details.
The right model for each message
Leave it on Auto and Kalle picks the model for each task. Or choose one yourself from the composer.
One conversation for the life of your app
Kalle keeps the pages, data and decisions from earlier messages, so you never have to explain your app twice.
Write in your own language
Kalle answers in the language you write in. Your app can be in a different one, or in several.
Questions about the chat builder
No. Describe what you want in plain words. The code is there if you or a developer want to read it.
Small changes take seconds. A first version of a full app usually takes a few minutes.
Each step uses credits. A small edit is about 1 credit and a full build 10 to 30. Plan mode shows the estimate before anything is built.
Yes. Pause at any time, or send a new message and Kalle adjusts the plan.
