About tkai
Honest numbers
The calculators show their assumptions and data sources. If something does not pay off, they say so just as clearly.
All in one hand
Development, operation and data protection are handled by one person. AI serves as a tool.
Sparing with data
The calculators run on servers in Germany, without advertising cookies and without tracking.
