Ark AI is an offline-first survival assistant built for when the internet is unavailable, unreliable, or completely gone. Designed for preparedness, field use, and self-reliance, Ark AI gives you a private on-device assistant that can help answer practical questions, organize notes, and search your saved reference material without depending on cloud servers. Ask questions, save useful answers, import documents, and build your own offline knowledge vault. Ark AI is built around one core idea: when you need important information, you should not have to depend on a signal. Features include: Offline AI Chat Ask practical questions directly from your device. Ark AI is designed to respond without relying on internet access once the local model is installed. Ark Vault Import PDFs and documents into your personal offline vault. Ark AI can search your saved material and show sources when information is pulled from your vault. Cited Sources When Ark AI uses your stored documents, it can show source cards so you can see where the information came from and open the original document. Ark Notes Save useful AI responses, observations, plans, and field knowledge into Ark Notes for later reference. Emergency-Oriented Design Built with a survival mindset for situations where fast, practical, and offline information matters. Private by Design Your local chats, notes, and vault content are stored on your device. Ark AI is designed to reduce dependency on cloud services. Practical Use Cases: Survival planning Emergency preparedness Offline research Field manuals PDF reference libraries Camping and outdoor planning Grid-down preparedness Bug-out planning Personal knowledge storage Self-reliance training Ark AI is not just another chatbot. It is a local survival knowledge tool designed to keep working when normal online tools may not. Important Notes: Ark AI requires downloading an on-device AI model before offline chat is available. This model is large, so Wi-Fi is recommended for setup. Ark AI is not a substitute for professional medical, legal, emergency, or rescue services. In a real emergency, contact local emergency services when available and use your own judgment. Introductory launch offer available for a limited time.

ScreenFox helps you reduce screen time by caring for a virtual fox whose wellbeing reflects your digital habits. The more mindfully you use distracting apps, the happier your fox becomes. Excessive scrolling makes it sad, and when it runs out of energy, distracting apps stay locked until tomorrow or until you help it recover through focused work. The Digital Fox Companion: At the center of ScreenFox is a virtual fox companion that reflects the user’s digital wellbeing. The fox has hearts that decrease when opening selected apps. Its emotional state changes based on remaining hearts: - Plenty of hearts: The fox is happy and smiling - Some hearts: The fox appears neutral - No hearts: The fox becomes sad and starts crying When no hearts are left, access to restricted apps is blocked for the rest of the day. Daily Limits & Reset System: Users define which apps to manage and set daily hearts. - Once there are no hearts left, access to selected apps is restricted for the day - Every unlock of restricted apps consumes a heart to use for a user-defined session length - At the end of each day, hearts reset to amount of hearts set This system encourages more intentional and mindful app usage. Focus Sessions: Focus sessions help users regain control and restore balance: - Restricted apps are blocked during focus time - Completing a focus session restores hearts - Restored hearts allow additional restricted app unlocks This creates a positive loop between focus and digital freedom. Additional Features: ScreenFox also includes tools to reduce impulsive behavior: - App launch delay before opening restricted apps - Session duration limits with reminders during extended usage These features encourage reflection and break automatic usage patterns. Motivation System: To support long-term habit building, the app includes: - Daily streaks - Tasks and achievements - XP and leveling system Users are rewarded for consistent mindful usage. User Control: All restrictions are fully user-defined and can be changed at any time. ScreenFox is designed to support awareness and self-regulation, not enforce control.
