Open Relay - Open WebUI Client

$4.99

Open UI is a beautiful, native iOS client for Open WebUI. Connect to your self-hosted server and chat with any AI model you've configured — right from your iPhone. Built 100% in SwiftUI, Open UI delivers a fast, polished experience with features the browser can't match. STREAMING CHAT WITH RICH MARKDOWN Get real-time, word-by-word streaming responses. Messages render with full markdown — syntax-highlighted code blocks with copy buttons, tables, math equations, block quotes, headings, and more. Everything flows smoothly as it streams in with no layout jumps. LIVE CROSS-DEVICE STREAMING Start a generation on the website and watch it stream in real-time on the app, token by token. Regenerations, title updates, follow-ups, and completion events all sync instantly between devices. CHART RENDERING When the AI outputs chart data in code blocks (Chart.js, ECharts, Highcharts, Vega-Lite, or Plotly), it's automatically rendered as a beautiful native Swift Chart right in the conversation. Supports line, bar, area, scatter, bubble, pie, heatmap, and histogram charts. Includes a Chart/Source toggle to view the raw JSON data. HTML PREVIEWS HTML code blocks are now rendered as a live preview instead of raw code. Includes a Preview/Source toggle, fullscreen mode, copy button, share sheet, and dark mode support — all in a scrollable sandboxed webview. VOICE CALLS WITH AI Have a real voice conversation with AI. Open UI uses CallKit for native iOS call integration, with animated visualizations that react to voice, real-time transcription, and familiar call controls. It feels like a real phone call. KNOWLEDGE BASES (RAG) Type # in the chat to browse and attach knowledge collections, folders, and files from your server. Your AI responds using the context you provide — just like the web UI. WEB SEARCH & CITATIONS Toggle web search per message. Your AI searches the web and responds with numbered source citations, favicons, and tappable links. TOOLS Enable server-side tools per conversation. Tool calls render inline with expandable arguments, results, and status indicators. REASONING / THINKING DISPLAY See the full chain-of-thought from models like DeepSeek and QwQ. Collapsible "Thought for X seconds" blocks let you explore the reasoning process. TEXT-TO-SPEECH Choose from four TTS engines: • Marvis Neural Voice — on-device AI voice powered by MLX • Server TTS — your Open WebUI server's endpoint • System TTS — Apple's built-in voices • Auto mode — picks the best available engine SPEECH-TO-TEXT Two STT options: • Apple Speech — fast, private, works offline • Server STT — server-side transcription FOLDERS & ORGANIZATION Organize conversations into folders with drag-and-drop. Pin important chats, bulk delete, and search across everything. Collapsible time-grouped sections keep things tidy. THEMING Light, Dark, and System modes. Pick an accent color from presets or a full color wheel. Enable pure black OLED mode and tinted surfaces. A live preview card shows your theme as you build it. RICH ATTACHMENTS Attach files, photos, and documents. Paste images directly into chat. Share content from any app using the Share Extension. QUICK ACTION PILLS One-tap toggles below the chat input for web search, image generation, or any tool. Customize which pills appear. NOTES & NOTIFICATIONS Create notes alongside your chats with built-in voice recording. Get notifications when a generation completes and tap to jump right in. ADDITIONAL SETTINGS • Default model picker synced with your server • Send on Enter toggle • Streaming haptics — feel each token arrive • Temporary chats for privacy • Configurable silence detection for STT Open UI is open source and doesn't collect your data. Your conversations go directly to your server — nowhere else. Requires a running Open WebUI server instance and iOS 18 or later.

### What's New - Added `@` model mention — type `@` in the chat input to quickly switch which model handles your message. Pick a model from the fluent popup, and a persistent chip appears in the composer showing the active override. The override stays until you dismiss it or pick a different model, letting you freely switch between models mid-conversation without changing the chat's default. - Added Open Terminal integration — enable terminal access for AI models directly from the chat input pill, giving the model the ability to run commands, manage files, and interact with a real Linux environment. - Added Terminal File Browser — swipe from the right edge to open a slide-over file panel. - Added native SVG rendering in chat messages - Added native Mermaid diagram rendering in chat messages (flowcharts, state, sequence, class, and ER diagrams rendered as beautiful images). - Added Memories management (Settings → Personalization → Memories) — view, add, edit, and delete AI memories that persist across conversations. - Added "Archive All Chats" option in the chat list menu for bulk archiving. ### Improvements - iPad layout overhaul - Sidebar drawer now slides smoothly with your finger - Returning to an existing chat now remembers the last model used in that conversation instead of reverting to the default model. - Unified TTS and STT under a single mlx-audio-swift package, replacing two separate dependencies for smaller app size and easier maintenance. - Improved audio transcription for long files with energy-based silence detection for smarter chunking at natural pauses. - User-attached images and files now display inline inside the message bubble instead of floating above it. ### Bug Fixes - Fixed excessive memory usage (1GB+) in long conversations caused by a windowing system that never actually freed off-screen messages due to a self-defeating freeze condition. Replaced with a simple always-render approach which is faster and stutter-free. - Fixed chat search using wrong query parameter, which could cause search to silently fail on some server versions. - Fixed tag removal using incorrect API endpoint format (path-based instead of body-based DELETE). - Fixed tag addition using wrong request body field name. - Fixed tags list fetching from wrong endpoint, now uses the correct structured tags API. - Fixed clone conversation not sending required request body. - Fixed feature toggles (Web Search, Image Generation, Code Interpreter) still appearing in the tools menu even when the admin disabled the capability on the model. Toggles now respect per-model capabilities. - Fixed tool-generated file download links opening in Safari instead of downloading within the app. Files are now downloaded and presented via the share sheet. - Fixed some chats created from the app appearing blank or corrupted on the Open WebUI web interface. - Fixed uploaded photos, PDFs, and other files not displaying on the Open WebUI web interface when sent from the app. - Fixed chat view becoming pannable in all directions after follow-up suggestions appear, instead of strictly vertical scrolling. - Fixed image uploads exceeding the 5 MB API limit by automatically downsampling photos to 2 megapixels before upload. - Fixed external response stream not stopping when clicking the stop button. - Fixed dollar amounts being incorrectly rendered as math equations instead of plain text. - false proxy error should be fixed
