* Works with the LM Studio API, OpenAI (GPT), Anthropic (Claude), and Apple Intelligence! * The LM Studio tab connects to any OpenAI-compatible API. * Each provider is tuned individually, including a high precision mode to control thinking level. * Personalize the prompt to tailor the app to your own needs. * Function calling is available for calendar events, reminders, notifications, web search and page fetching, location data, on-device memory, knowledge base search, image generation, and user interaction. * For example, you can summarize, add, and edit your schedule in natural language. * Add your own documents and let the AI search them (RAG). * Change the background using images from your Photos library. * You can ask AI to set notifications and list reserved notifications. By default, the app opens the conversation by listing today's remaining calendar events — or tomorrow's, if none are left. This behavior can be customized in your language on the settings panel. You can instruct the LLM in natural language, for example: "Search the next US holiday and add it to my calendar". The app automatically replies in your device's default language. [Note] * This app is provided free of charge for research purposes. * Use it at your own risk, and do not rely on it for critical or high-stakes decisions. * The current time on your device is sent as the initial user prompt, and your device's language setting is sent as the system prompt. * When function calling is enabled, the app sends data from your device to the AI you selected. This may include calendar events, location data, saved notes, and excerpts from documents you have added to the RAG knowledge base. * Image generation is available with OpenAI models only. * API usage fees apply when you use OpenAI or Anthropic models with your own API key. * The software is provided "as is," and the author assumes no responsibility for its performance. * This app is a technical demonstration of LLM usage and should not be used for critical decisions, including business or medical purposes. * The content of AI-generated responses depends on the model you select. * AI may generate incorrect responses, and their accuracy is not guaranteed. [Safety Measures] * You are asked to confirm after every five consecutive function calls. * In Safe Mode, adding or editing a calendar event requires your confirmation through the standard iOS interface. * Deleting a calendar event always requires your confirmation, whether or not Safe Mode is enabled. * Location access is managed by the standard iOS permission system, and only approximate location data is used. [Apple Intelligence Limitations] * Requires an Apple Intelligence–compatible device running iOS 26 or later. * Limited context window: enabling many tools can exceed it, causing the model to skip tool calls and hallucinate. Disable tools you don't need. * Safe Mode is always on for calendar operations. * Tool calling stops with an error after 20 consecutive calls.
