The Kaft promise
What every app promises
Each app has its own name, colour and character. The promise is the same for all of them.
Understanding over cramming
Every topic starts from a question or a picture, not from a formula to learn by heart.
Connections
You see where a topic comes from, where it leads and where it turns up in another subject.
Do it yourself, explained at once
Exercises are checked on the spot, with a hint, a worked solution and always a fresh variant. Mistakes are information, not punishment.
Honest
What is uncertain or disputed is shown as such. Content is marked concept until a teacher or subject expert has checked it.
Fairly priced, private, calm
Draad is entirely free, and in every other app the learning path and the first topics are free. No ads, no tracking, no guilt-driven notifications.
Flemish and Belgian
We start from the Flemish curriculum goals and examples from here: euros, Belgian cities, the train from Brussels to Ghent. In four languages.
How it fits together
One cover, every app its own book
Kaft is the front door. Each app is its own site with its own name, colour and address, so each can grow at its own pace. Kaft holds them together and shows where they meet.
To be honest: for now, each app keeps your progress only on your own device. Kaft cannot see it. That changes only with a single Kaft account.
One cover
Here you see every app, how far along it is, what it costs, and how the subjects connect.
Every subject its own app
Ruit for maths, Spoor for history, and so on. Each app works on its own, even on an old phone.
Later, one account
A Kaft account without a password, with a code by email, that shows your progress across all apps.

- No pupil accounts. No email address, no password. Progress stays on the pupil's device.
- Worksheets for each topic. Printable and with answers, following the Flemish learning goals. They are on their way, starting with Ruit.
