Choosing a model shouldn't be your job
A casual question doesn't need the most expensive model. A 3,000-word report shouldn't go to the cheapest one. We do that math for every task and route it to the right model. You don't see the process—you just see the answer.
Switch models without switching code
Providers raise prices one day, go down the next, and ship new versions after that. We switch routes automatically on our end—you don't have to change a single line.
Zero setupNo installs, no code. If you can type, you're set.
