Document Packets assembles source PDFs into one organized handoff with a linked contents page, optional dividers, section bookmarks and a companion source map. HOW IT WORKS 1. Open Document Packets from the home screen. Add source PDFs from Files, or explore the clearly labeled sample packet. 2. Name and reorder the sections, select the source page ranges, and choose whether to include section dividers. 3. Build the packet, preview the indexed PDF and share it with the source map. Finished packets remain in the local library until you delete them. Scanning, OCR, page organization, merging, extraction, stamps, signing, redaction, password-protected copies and image export remain available. Packet assembly stops on missing pages rather than silently omitting them, and source files remain untouched. WHAT TO KNOW Up to 20 unencrypted source PDFs, 50 MB per source, 150 MB total input and 400 selected source pages. Imported page sizes and rotations are checked after assembly. A packet is a new PDF: original digital signatures are not preserved, and forms, links and other interactive content need recipient verification. Page numbers are one-based. Source hashes identify exact input bytes without certifying document authenticity. iPhone and iPad.

Keep AI on your phone instead of sending every conversation to the cloud. SageMind is a private, offline-first AI assistant that runs models on your device. No account is required, and everyday conversations, skills, favorites, and session history stay local. After the first model download, SageMind remains useful in airplane mode, while traveling, or whenever your connection is unreliable. Chat naturally or run Sage Skills directly: learn one useful English word, create an original inspirational quote, start a Sudoku puzzle, or import personal tools into your own skill library. Results appear as clear cards that are easy to save, share, and revisit. Daily words and inspirational quotes can live on your Home Screen as widgets. Favorites update the widgets, turning local AI from an occasional chat box into something useful every day. The first use requires an internet connection to download a recommended model. SageMind chooses a suitable model for your device and clearly shows its download size. Once downloaded, the model is cached locally. Advanced users can choose other compatible models and manage storage from the app. SageMind supports multiple languages plus light, dark, and system themes. Conversation history, favorites, and personal skills are stored locally without requiring an account. If you value privacy, deal with unreliable connections, or want AI to become a useful daily tool instead of another cloud service, SageMind is built for you.
