Silo lets you control what AI knows. Your memory, your services, your context — in one place, working across every AI model. Silo is the only control layer between your data and the models that use it. Privacy is the foundation. Ownership is the product. Portability is the growth engine. ---- ONE MEMORY, EVERY MODEL Most AI tools trap your history inside a single platform. Your ChatGPT conversations can't move to Claude. Your context resets every time you switch tools. Silo fixes that. Your memory lives in your Silo — on your device, encrypted, portable. Switch between ChatGPT, Claude, Gemini, and more without losing context. One subscription, every model. Nothing gets stuck. ---- A NEW KIND OF FILE When we separated memory from AI models, we created something new: the .silo file. A portable, shareable, structured knowledge package that any AI can query. Share a travel plan that adapts to whoever opens it. Build a company knowledge base grounded in your actual thinking. Package what you know and send it to a collaborator. Authored, not interpreted. Interactive, not static. Yours to share. ---- PRIVATE WHEN IT MATTERS Private Assist runs AI entirely on your device. No internet required. Start a conversation locally, or switch to it mid-conversation when something becomes sensitive. Your data never has to leave your device. But when you choose to use cloud models, Silo always asks before sharing anything. ---- INTELLIGENCE ON YOUR SIDE Silo governs every interaction between your data and AI: · PII scrubbing before data reaches any model · Audit trail of what was shared and when · Instant access revocation · You control your encryption keys Every AI that wants your data asks Silo first. You set the policy. ---- CONNECT YOUR WORLD Silo extends beyond memory. Connect services like Google, Dropbox, and Plaid to your Silo. Any AI you authorize can access them — governed, auditable, revocable. One dashboard, one policy layer, full control. ---- GETS BETTER OVER TIME The more you use Silo, the more your context compounds. Memories connect across conversations. Responses become more personal. Your Silo becomes the most complete picture of what matters to you — owned by you, useful everywhere. ---- Control what AI knows. Own yourself.

KeyoAI is an AI-powered keyboard and creative studio for iPhone. It helps you write faster and with more confidence in the apps you already use, and it also lets you generate images, video, and audio from simple prompts. Add KeyoAI in Settings under General → Keyboard → Keyboards, then switch to it when you type. AI Keyboard Get smart suggestions as you type so you can finish thoughts quickly and keep your flow. Open built-in AI tools from the keyboard to improve grammar, adjust tone, translate, summarize, rewrite, draft replies, and handle everyday writing tasks without leaving the app you are in. AI Chatbot Use the in-app AI Chatbot for longer conversations and deeper help—brainstorming, drafting messages and emails, refining content, and iterating with context. It’s ideal when you need more than one-line keyboard assistance. AI Image, Video, and Audio Create content directly in the app: Generate images for posts, ideas, and visuals Generate short videos based on your prompt and selected options Generate audio for concepts, backgrounds, and quick creative experiments AI Trading Use AI Trading in the app with a chart screenshot from your gallery or camera. KeyoAI turns it into structured, narrative-style commentary—ideas around levels, scenarios, and context—for learning and brainstorming only. This is not personalized investment, tax, or legal advice, not a recommendation to buy or sell any security, and not a substitute for your own judgment or a licensed professional. Availability and pricing (including subscription or pass options where offered) are shown in the app before you use the feature. Designed for everyday use KeyoAI is built for messaging, email, notes, and social posts—plus fast creation when you need visuals or media, and optional chart reads when you want a second lens on a screenshot you already have. Whether you want clearer wording, a friendlier tone, a shorter version of what you wrote, or a brand-new image/video/audio idea, you can do it from one place. Internet access and control Some features use the internet to run AI. On iPhone, third‑party keyboards need Full Access turned on for features that use the network. You stay in control and can change Full Access or remove the keyboard anytime in Settings. Subscriptions and billing Subscription options (and/or passes) may be available in the app to unlock premium AI features—including AI Trading where offered. Details and pricing are shown in the app before you purchase. Privacy and support We care about transparency. A privacy policy is available inside the app on the Contact Us screen. If you have questions or feedback, use Contact Us in the app to reach support. KeyoAI is built to make typing on your phone feel smarter and simpler—and to give you an all-in-one AI studio in your pocket.
