AIX Promptplay
A client-side playground for running the same prompt across multiple language models and comparing the results side by side.
A sketchpad for prompts
I wanted to see how different language models answer the same prompt, side by side, without juggling three consoles and a stack of API keys. So I built the thing I wanted: one input, several models, the answers next to each other.
It is a hobby project and it looks like one on purpose: fast to open, fast to change, no ceremony.
Client-side on purpose
Everything runs in the browser. No backend holds your keys, no server sees your prompts, and there is no account. That was not a performance decision but a trust one: a tool for experimenting with half-formed ideas should not quietly keep them.
It has become how I actually work out prompts, which is the only real measure of a tool built for yourself.
