Making Of GPTokenz
A public build log and forward-looking themes. Security-sensitive values are intentionally excluded.
How GPTokenz started
GPTokenz began as a 30-day experiment to validate focused, rapid end-to-end lean app development. Learn by shipping, not by theory. Build fast, fail fast.
The product idea is simple on purpose. A clean no-gimmicks interface that's for the everyday person with a focus on privacy and affordability - allowing users to have access to premium models from just USD$1.
In creating GPTokenz, we hope to reduce the barriers and encourage adoption for daily / regular use outside of work and tech-enthusiasts.
