So helpful

As someone who has used AI for years, I know I rely on it too much. Rusty helps me stay sharp and not so dependent.

Response from developer

Thank you! This is the exact reason we built Rusty.

Great

Onboarding was amazing and training was good. I feel after a month or two I might adapt to the difficulty so they should add progressive difficulties.
