Why TopArrow

Your data stays on your own computer

Software and data stay on your own device. They do not depend on the cloud, so you do not have to worry about a service shutting down or an account going away. It still works offline.

If it does not fit, change it

If something feels awkward or a feature is missing, tell the AI how you want it changed and it will modify the software for you. You do not need to learn programming from scratch, and you do not have to rebuild the software.

With working software as the base, AI changes are more reliable

Asking AI to write a complete app from zero often goes wrong in all kinds of ways. TopArrow gives you software that already runs; you only ask AI to change the parts you care about.

A version you changed can become your work

Software you modified can be published on the TopArrow market for others to download and use, and you can earn from it.
