Imagine a world where you're hiking in the mountains, far away from any cell towers, or perhaps you're on a long flight with no internet access. You suddenly have an idea or a question pop into your mind—something you want to explore, learn about, or even just chat about. What if, in those moments, you could turn to an app on your phone that didn't need Wi-Fi or cellular data? An app that could engage in meaningful conversation, provide insights, answer questions, or help you brainstorm, all while being completely offline? Models may take 5+ minutes to load, but they continue to stay loaded after downloading A Conversational AI LLM Open Source Implementation of LLAMA.CPP Welcome to the future of AI-powered conversations—an app built on the open-source implementation of LLAMA.CPP, a powerful, lightweight machine learning model designed to run directly on your device, without the need for any external connections. Leveraging the flexibility and efficiency of the LLAMA.CPP implementation, this app provides users with a reliable and responsive AI that you can count on anytime, anywhere. But what makes this truly game-changing? Rhetorical Questions to Ponder: Have you ever been in a situation where you needed help, but there was no internet connection? Think of all the times you've been in a remote location, perhaps on a camping trip or traveling abroad, and needed information. Whether it’s a language translation, a quick piece of advice, or even just someone to talk to, this app could be your companion. What if your privacy concerns mean you prefer not to have your data processed by cloud-based services? Many AI-powered apps require constant internet connectivity to function because they rely on sending your data to servers for processing. But with this app, everything happens locally on your device, ensuring that your conversations remain private and secure. App Features: Offline Access: Download the app once, and it's ready to use anytime, anywhere—no service, no problem. Lightweight and Efficient: Optimized for low-memory usage, the app runs smoothly on a wide range of devices, from high-end smartphones to older models. Privacy-Focused: Since all data processing happens locally, your interactions remain confidential and secure. Versatile Conversations: Whether you need help with a task, want to brainstorm ideas, or simply chat, the AI is designed to engage with you in a meaningful way, offering suggestions, answering questions, and providing support. Imagine the Possibilities: Travel Companion: When exploring new places, use the app to learn about the local culture, get language tips, or even just keep yourself entertained during long journeys. Study Aid: Use it to help with homework, understand complex topics, or prepare for exams, all without needing to worry about internet connectivity. Brainstorming Partner: Whether you’re an entrepreneur, a writer, or just someone with lots of ideas, the app can help you refine your thoughts, generate new concepts, and explore different angles. In a world increasingly dependent on connectivity, this app offers a refreshing alternative—a powerful AI assistant that is always at your fingertips, no matter where you are. Powered by LLAMA.CPP, it embodies the essence of independence, privacy, and reliability. Whether you're deep in the wilderness, in the middle of a power outage, or simply wanting to disconnect from the online world, you can rely on this AI to be there for you, providing the support and interaction you need, whenever you need it. So, why wait for an internet connection to get the answers or interaction you need? Download this app and experience the freedom of truly offline AI conversations.

About

ChatOKF

Features
Read full description

A capable AI assistant that lives on your iPhone and iPad. The model runs on your device's own chip, so nothing you type is uploaded and nothing is logged. Once a model is downloaded, ChatOKF works in airplane mode. No account. No sign-in. No subscription. No ads, no analytics, no telemetry. WHAT YOU CAN DO - Ask anything: check the math on a loan, plan a week of dinners, untangle a confusing letter. - Show it a picture: a photo of a menu, a street sign or a whiteboard, straight from your library. Some models also listen to audio and watch video, frame by frame. - Hand it a document: a PDF, a Word file or a spreadsheet. It reads the tables inside and answers from the file, and one tap opens the page to check it. - Watch it think: the stronger models reason before they answer. Read the reasoning, tap Quick Answer to cut it short, or switch thinking off for speed. - Let it look things up: Wikipedia, today's headlines, the weather and web search are tools it can use, each behind its own switch. - Keep going: it suggests a sensible next question; swipe right to ask it. - Keep what it gives you: answers are typeset, tables and mathematics included. Search and rename your chats, share one as a PDF, and bring a deleted chat back within thirty days. - Talk instead of typing: tap the microphone and speak, and have replies read aloud in one of ten voices made on your device. MEMORY YOU CAN READ Tell it to remember something and it writes a short note, and the chat says what it wrote. Later questions are checked against your notes first, whichever model is answering. Every note is listed under Memories, to read or to delete. One switch, Total Recall, turns it all off. WHERE YOUR WORDS GO Nowhere, unless it looks something up. With Wikipedia on, your question is matched to an article on your device and only that article is downloaded. With web access on, the model's search terms go to a search engine and the pages it chooses are fetched. Settings, Privacy says exactly what leaves your device for each one. PICK YOUR MODEL Several open models are offered, and the list shows only what your device can hold, so every one you see will run. - Gemma 4 E2B and E4B: they see pictures, hear sound and watch video. - Qwen3.5 2B and 4B: good with tools and longer answers. - Ternary Bonsai 1.7B: small and fast, for devices with less memory. GOOD TO KNOW - The first launch downloads a model, from about half a gigabyte to a few gigabytes. Use Wi-Fi; after that, no network is needed. - Devices with more memory are offered stronger models, and newer chips answer faster. - Answers are generated and can be wrong. Check anything that matters. ChatOKF is written in Swift on Metal, and its source is on GitHub. Models are provided by their authors under their own licenses, including the Gemma Terms of Use.
