FAQ
Common questions
What does the Pencil Generate Video Ad automation do?
Generate AI-powered video ads using Pencil
Do I need an API key or integration?
Usually not. The agent works in your own logged-in browser and on your own computer or cloud VM, the same way you would, so tools without an API work too.
Will it act without asking me?
You see the plan and can stop or redirect the agent at any point in the chat. Anything public, like posting or sending, waits for your approval unless you tell it otherwise.
Can I change the instructions?
Yes. Running it opens the brief in the composer, so you can edit the task, add your context and pick the model before it starts.
What does it cost?
The free plan runs it on Claude Sonnet. Paid plans start at $20 a month and include every model provider.
