FAQ

Does my data really stay private?
Yes. Processing happens on-device and no text or images are sent to external servers.
What documents are supported?
Contracts, specs, meeting notes, papers, technical docs, and more. Japanese and English are supported, and handwritten notes are OK.
What are some examples of private conversations?
Examples: "Analyze the emotions in this journal," "Give advice from my health notes," "Turn my secret plan into a TODO list," and more. You can chat freely.
Can I use it offline?
Yes. Since AI runs on-device, core features work without an internet connection.
Is it normal for my device to heat up when using the app?
The app performs intensive data processing, so your device may heat up during long chats or extended use. This is common for apps that handle heavy processing. To use it comfortably, avoid continuous use in cases that trap heat or on fabric surfaces, and take breaks to let the device cool down.
The app unexpectedly quit. Is this a problem?
The app uses significant memory, so it may quit unexpectedly on some devices due to iOS limitations. For stable operation, we recommend closing other apps or using a device with sufficient memory (e.g., iPhone 14 or later).
