BuildBrief Quick does not bundle its own AI model and does not send ideas to a cloud fallback. A device that cannot provide the required system model will show an unavailable state.
Availability messages
The model is not available on this device
The device or operating-system configuration cannot currently run the required on-device model. Confirm that the device supports the relevant platform AI feature and that system software is current.
Turn on Apple Intelligence
On iPhone or iPad, enable Apple Intelligence in Settings, allow its model to finish preparing, then return to BuildBrief Quick.
The system model is preparing
Keep the device connected to power and Wi-Fi while its operating system completes the model download or preparation. Reopen the app when the platform reports that the model is ready.
Generating a brief

Generated output is AI-assisted and may be incomplete. Review it before using it to make a business, product, or engineering decision.
