HivemindOS Mobile is a mobile command center for AI agents that do real work — not just code. Chat with an agent that can write and ship software, generate images, research a topic, take notes, and run your operations — from your phone, wherever you are. Three ways to run, no lock-in: • YOUR SERVER — point the app at your own machine or VPS and drive a full agent remotely over an encrypted tailnet or your own connection. • ON-DEVICE — run a local model entirely on your iPhone with Apple's MLX. Fully offline. Nothing leaves the phone. • PAIRED TO YOUR MAC — connect to the HivemindOS desktop app and talk to your whole fleet of agents from anywhere. Scan a QR code once and you're in. BRING YOUR OWN MODEL Anthropic (API key or Claude subscription via OAuth), OpenRouter, additional cloud providers, and local inference servers such as Ollama, LM Studio, llama.cpp, and vLLM. Build a model queue with automatic fallback and retry, and switch models per chat. DOES MORE THAN CODE • Generate images right in the chat and save them to your phone • Write, edit, and ship code with a real interactive terminal per conversation • Research, summarize, and draft with streaming responses and live tool tracking • Image and file attachments for multimodal models • A shared brain (Obsidian vault) that gives agents memory across sessions • Wallets, autonomous companies, and an approvals inbox when paired to a hub VOICE, SHORTCUTS & MORE • Call your agent — a real voice conversation, with a fully on-device speech pipeline for offline calls • Apple Shortcuts, Siri, and Action Button: capture a note, add a task, ask a question, or hear a daily briefing • Plan mode that blocks writes at the runtime layer, not just by prompt • A fleet of named agents, each on its own model — chat or call any of them PRIVATE BY DESIGN Your chats go to the machines and model providers YOU choose — your server, your Mac, or the provider whose key you entered. Your HivemindOS account keeps your profile and credit balance consistent across your connected devices. Diagnostics stay on your device. Open source. Built by a solo developer who wanted a genuinely good way to get things done from a phone. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Nook is the journal that calls you. Every evening, at a time you pick, your phone rings. You answer, you talk for five minutes, and that's it. Journaling fails because it waits for you to start every single time. Nook starts for you. Like when your mom calls and asks how your day was, and you end up telling her things you didn't know you were thinking. Months later it still remembers all of it, so you can ask it what you've been circling and get a real answer. IT STARTS BY ASKING Your first call is a conversation. Nook asks what matters to you right now, what you're working on, and when you want to be called. It writes all of it down, and it brings it up later. THEN IT JUST CALLS Five minutes a day at your time. It remembers what you said yesterday and asks about the thing you're actually avoiding. Every call becomes a written entry, and once a week Nook pulls it all together into one recap. ASK IT ANYTHING This is the part that's hard to do with a notebook. Nook has everything you've said, so you can ask it about yourself: "Where am I falling short?" "What have I stopped mentioning?" "What's been draining me?" "What patterns do you notice?" And it answers properly. One user asked which goals she'd been neglecting and got told she hadn't been writing much, and hadn't touched German since she said she would. That's the thing a blank page can't do. It doesn't remember anything. IF YOU DON'T PICK UP, NOTHING HAPPENS No guilt. No broken chain. It just tries again tomorrow. Nook is the version you're still doing in a month, not the one you feel bad about in a week. MAKE IT YOURS Custom icons and a look you can set up the way you like. It should feel like somewhere you want to go at the end of the day. YOUR CALLS AREN'T RECORDED Nook doesn't keep your audio. You talk, it becomes text as you speak, and the recording never exists. That text is deleted after 12 months. No ads, no trackers, nothing sold to anyone. Delete your account and everything goes with it.
