Common questions.

Does LucidPal work without Wi-Fi? +
Yes — completely. Once the model is downloaded, LucidPal operates 100% offline. No network request is made at any point during a conversation.
Which iPhone models are supported? +
Any iPhone running iOS 16 or later. For the best experience, iPhone 12 or newer is recommended. The 4B model requires iPhone Pro class devices with 5 GB+ RAM.
How is this different from Siri? +
Siri routes your requests through Apple's servers. LucidPal runs a full open-weights language model (Qwen3.5) directly on your iPhone — nothing leaves the device. You also get a persistent chat history, thinking mode, and more nuanced calendar control.
Can it read my existing calendar events? +
Yes. LucidPal reads from all calendars you grant access to — iCloud, Google, Exchange, and local calendars — via the iOS EventKit framework. Nothing is ever copied off your device.
What are the premium features? +
The core app — chat, calendar access, voice input, and all current features — will always be free. Premium features (coming soon) will include additional model options, advanced templates, and more. Pricing has not been announced yet.
When is the App Store release? +
We're targeting an App Store release soon. Join the waitlist below to be notified the moment it's available.
