FAQ
Common questions
Which AI models can I use?
Bring your own key for Google Gemini (Gemini 3 Pro, 3.1 Flash / Nano Banana, 2.5 Flash) and xAI (Grok Imagine Image and Pro). More providers are coming — you always pay the provider directly, with no markup from us.
Do I need my own API key?
Yes. Paste a Gemini or xAI key in Settings and babbleBrush calls the provider directly from your Mac. Generations are billed by that provider, not by us.
How does pricing work?
The app is a one-time purchase — pay once, keep it forever, with a full year of updates included. Image generation is pay-as-you-go through your own provider key.
How many Macs can I use it on?
Each license activates 1 Mac. You can free that seat anytime from Settings → License and activate on another Mac.
Where are my images and history stored?
Entirely on your Mac. Canvases, versions, and edit history are kept locally — nothing is uploaded to our servers.
