Always wanted an AI like those in the movies? An AI assistant with actual personality who's also useful - and one whose look you can design yourself? Daimond AI lets you create your perfect AI companion. Customize personality, voice and name. Generate a custom illustrated character built from your companion's personality, or pick one of 10 animated companions. Then talk through ideas, search the web, check your schedule, or get a second opinion - by text or voice, online or offline. PERSONALITY + PRACTICAL TOOLS Tired of robotic, one-size-fits-all AI? Love character apps but wish they could help with actual tasks? Daimond offers both: Personality + Practical Tools. Name Your AI Pick a name that fits their personality. Shape Your Character Adjust personality traits with intuitive sliders - then generate a matching illustrated character with Apple Intelligence. Choose a Voice Multiple natural voices make conversation feel real, not robotic. MEET YOUR COMPANION Generate your own illustrated character with Apple Intelligence, created from your companion's personality traits - or pick from 10 built-in animated characters. Your Companion appears in chat and speaks the words. Add matching Thinking and Greeting expressions so your character reacts while Daimond replies and greets you each morning. Character generation uses Apple's Image Playground and requires Apple Intelligence on a supported device. The 10 built-in animated companions remain available on other devices.

Sessions AI is a private AI workspace that runs entirely on your iPhone, iPad, or Mac. Not just a chat box: it uses real tools, works from your own documents, and creates images—all on device, with no account and no cloud. More than a chat box Most on-device AI apps just run a model. Sessions AI gives the assistant real tools and lets it do the work: calculate, convert units, look things up on Wikipedia, check your calendar, add reminders, search the web, fetch a page, generate an image. Ask for something involved and it writes a plan first—which you can read, edit, and approve before it spends a moment of compute. You see every step it takes. Ask by voice, or from a Shortcut Say "Start a chat in Sessions AI" to Siri and speak your question—it opens the app and lands the answer in a real conversation you can carry on. The Ask Sessions AI action appears in Spotlight and the Shortcuts app too, so you can build it into your own workflows. Ground answers in your own knowledge Give a persona its ownprivate knowledge base—add documents from a file or a URL, including Word, RTF, and PDF. When you ask a question, Sessions AI searches that content on device and bases its answer on it, and shows you which passages it used. Nothing is uploaded; indexing and search happen locally. Personas that keep work separate Set up a persona for each kind of work, each with its own system prompt, knowledge base, and connected tools. Switch per chat. Research stays separate from writing, and work stays separate from home. Bring your own tools (MCP) Connect Model Context Protocol servers and their tools appear right in your chat, alongside the built-in ones. Add custom HTTP headers for authentication, stored securely in the Keychain. It's your workspace—extend it however you like. Create images on device Ask the assistant to draw, sketch, or visualize—and it generates images right on your device, no cloud APIs. Choose from fast models like Stable Diffusion XL Lightning and Z-Image Turbo through to higher-quality ones like FLUX.2 Klein, with larger models such as Qwen Image on high-memory Macs. Watch a live preview as it draws, start from one of your own photos with image-to-image, and reuse the seed shown with each result to reproduce or vary it. Browse everything you've made in a built-in Gallery. Your chats are yours Every conversation is saved on your device as a plain Markdown file you can open in the Files app—no proprietary format, no lock-in, no export button needed. Pin, rename, group, and search across every chat by name or content. Your model, your choice Sessions AIruns open language models in a range of sizes—Gemma, Qwen, Ministral, Mistral, and Ternary Bonsai families among them. Pick a small, fast model for quick answers or a larger one for harder work, and set a different model per conversation. Download only what you need; remove any model to free space. Made for every screen Designed for iPhone, iPad, and Mac, with full Dark Mode support. On iPad and Mac, a roomy sidebar lets you group and pin chats and jump between your models and Gallery; on iPhone, a simple tab bar keeps everything a tap away. Built for privacy Chat transcripts, the knowledge base, and all model data stay on your device. Language models and image generation both run locally—nothing you type is sent to the cloud for AI processing. Calendar and reminder access are used only on device to answer your questions. Web search is optional; when enabled, only the search query is sent to the provider (e.g. DuckDuckGo), not your full conversation. No telemetry, no analytics, no account—just you and your device. Who it's for Sessions AI is for anyone who wants a capable AI workspace without handing their work to the cloud. Whether you care about privacy, work offline, or simply prefer to own your data, it gives you a full assistant that runs where you do: on your own device.
