Your AI. Your server. Your pocket. Open Relay is a fully native iPhone, iPad, and Apple Watch app for Open WebUI. Chat with any model on your own server in a fast, polished app built on Apple's frameworks, including Liquid Glass on iOS 26. — STREAMING CHAT, BEAUTIFULLY RENDERED — Responses stream in live with full markdown: syntax-highlighted code, tables, math, Mermaid diagrams, SVGs, live charts, and interactive Rich UI embeds from your tools. Run Python code blocks with a tap. Continue, fork, rate, or listen to any reply. — VOICE CALLS & DICTATION — Call your AI like you'd call a friend. CallKit makes it feel like a real phone call, with an animated orb that reacts as you talk. Dictate hands-free with a live timer on the Lock Screen and in the Dynamic Island. — PRIVATE, ON-DEVICE VOICE — Neural text-to-speech and speech-to-text run entirely on your device using Apple's MLX. Download once and nothing leaves your phone. Server and system voices are supported too. — APPLE WATCH — Read and reply to your chats and channels, or ask with Siri, right from your wrist. — A POWERFUL COMPOSER — Type @ to switch models, / for prompts, # for knowledge, and $ for skills. Attach files, photos, notes, or knowledge bases, and queue messages while the AI is still replying. — TOOLS, AGENTS & TASKS — Turn tools on or off per chat, connect MCP tools that need sign-in, approve tool actions, and answer the model's questions inline. Agentic models plan multi-step work in a live task list. — TERMINAL — Give your AI a real Linux terminal. Browse, search, edit, and preview files, upload whole folders, preview running ports, and watch the model's commands run live. — KNOWLEDGE (RAG) & SEARCH — Organize knowledge bases into folders, upload or sync entire directories, and search across your chats, files, and documents. — NOTES, CALENDAR & AUTOMATIONS — Write and share notes, and chat with the AI about them. Manage calendars, repeating events, and invitations. Schedule prompts to run automatically. — CHANNELS — Team chat rooms for people and AI models, with direct messages, threads, replies, reactions, webhooks, and notifications. — ORGANIZE EVERYTHING — Folders with their own system prompts, models, knowledge, emoji, and backgrounds. Shared folders, pinned chats, unread markers synced with the web, bulk archive, and share links with access control. — WORKSPACE & ADMIN CONSOLE — Manage models, knowledge, prompts, skills, and tools. Admins can run the whole server from the app: users, groups, connections, functions, MCP servers, evaluations, analytics, and settings. — WORKS EVERYWHERE YOU DO — Home Screen and Lock Screen widgets, Shortcuts, the Action Button, the Share Extension, and deep links. Reply straight from notifications, and get alerted when a response finishes in the background. — YOUR SERVERS, YOUR WAY — Save multiple servers and accounts and switch instantly. Sign in with a password, LDAP, SSO, passkeys, or Face ID. Works behind Authelia, Authentik, Cloudflare, custom headers, and client certificates (mTLS). — MAKE IT YOURS — Accent colors, a pure black OLED mode, customizable message actions, and separate text sizes for messages, titles, the message box, and the rest of the app. Requires your own Open WebUI server. Your models. Your rules.
