How StepFun: Step 5 Preview works in Pluely
- One tap to switch. Open the overlay's model picker, search "StepFun: Step 5 Preview", click — your next question uses it. See the model picker.
- Works everywhere in the app. Ask mode questions, automatic responses in meetings, transcript summaries, and follow-ups all run on whichever model you selected.

- Private by design. Conversations stay on your device, and Pluely never exposes its serving infrastructure to the app.
