Why Wurzelwerk exists
Understanding is worth more than the quick answer.
Wurzelwerk grew out of everyday IT work. There you learn fast: fix only the symptom and the same problem is back tomorrow. Understand the cause and you solve it for good, and can explain it to others.
Many AI tools hand out finished answers and take exactly that understanding away. Wurzelwerk goes the other way: it asks, shows ways to a solution and keeps track of what you learned.
- ✓Independent project from Germany, no ads
- ✓No selling of data, no cookies, no tracking
- ✓Free for all users, the project pays for the servers
- ✓Built with the pilot group: feedback goes straight into every version
Frequently asked questions
Good to know.
What does Wurzelwerk cost?
Nothing. The local AI on your device is free. If you also want to use Claude, you connect your own account with the provider and only pay there for what you use. Wurzelwerk earns nothing from it.
How do I get the app?
Through the pilot group: request access, confirm your email address, wait for approval. You then get a personal invitation link that is valid for 14 days. There is deliberately no open download.
Which devices does Wurzelwerk run on?
In the browser on phone, tablet and computer, with Chrome, Edge, Safari or Firefox. An installable web app and an Android app will follow. How large the local AI can be depends on your device.
Where is my data stored?
On your device. Backups and the upcoming sync are encrypted on the device first, and only you know the key. Servers and database are in Europe.
What happens to my Claude key?
It stays encrypted on your devices and only goes directly to the provider. Before any text gets there, Wurzelwerk replaces personal details such as names, addresses or phone numbers.
Can you cheat with Wurzelwerk?
That's not the point. Wurzelwerk shows ways to do it yourself instead of finished answers. Certificates have time limits and anomaly detection, and when in doubt a fair retest follows.
How do I delete my request?
A short email to kontakt@wurzelwerk.online is enough. Unconfirmed requests delete themselves after 48 hours, all others after 12 months at the latest.
