Good to know
How does smart model routing work?
With Auto on, Sheila reads your request and picks from the available AI engines. Everyday questions tend to use an efficient engine. Harder requests can use a stronger one. You can also choose a mode yourself.
What are tokens?
Tokens are small pieces of text used to count what you send and what Sheila writes back. Longer chats and stronger models can use more credit.
How much can I use for free?
New accounts get $2 in starting credit. The number of messages depends on their length and the model used. You can see your balance in the app.
Is Sheila part of another AI app?
No. Sheila is its own chat workspace. It uses supported AI engines behind the scenes. Other AI apps and their paid plans are separate.
