# Ready-made personas you can switch on and off

_Released August 18, 2026_

Every account now comes with system personas for engineering, writing, studying, thinking a problem through and content, and you can switch off the ones you do not want.

Open Personas to find the System personas that ship with GPTree, each with a short description of what it is for. Pick one for a message, or set one as your default.

Switch off any you do not want and they stop appearing in the persona picker in your conversations.
