How do I choose a different AI model for a problem?
On the Solve screen, find the AI model selector near where you enter your math problem.
Select the model you want to use, such as ChatGPT, Gemini, or Claude, and then submit your problem as usual.
PercenX will send that problem to the model you selected.
Changing the model on the Solve screen lets you choose the AI you want for your current math work. You can also change your default AI model in Settings if there's one you prefer to use most often.
Tip: You don't have to use the same AI model for every problem. Feel free to try another model when you want a different explanation or approach.
