Redde is a complete iPhone and iPad client for Hermes, the open-source AI agent, with CarPlay and an Apple Watch app. Talk or type, watch it think and use tools, approve what it runs, and give it a crew: bots with faces and voices of their own, alone or in group chats. You bring the backend. Redde has no account and no analytics, and your conversations go only to your server, and to a voice service if you pick one. BOTS • Each Hermes profile is a bot with a face, a voice and a chat of its own. Start one from a template (Researcher, Writer, Coder, Home, Planner) and make its job, personality, model, face and tools your own. • Type @ to hand work to another bot. Put two to six in a group chat and they answer in turn; talk to the room and each answers in its own voice. • Give a bot a schedule and its answer arrives in its chat, with a notification, even with Redde closed. Mute any chat. • Ask a bot from Siri, CarPlay, the Apple Watch or a spoken word. TALK, DON'T TYPE • Tap the mic or say "Hey" and your agent's name, ask, hear the answer, or show it what the camera sees. Speech is recognized on your iPhone; the reply is spoken by the built-in voice, Kokoro, ElevenLabs or your Hermes. • Or talk live, interrupting any time, with GPT-Live, Gemini Live, Grok Voice or ElevenLabs on your own key. • Hands-free keeps the conversation going until you say "that's all". Talk over an answer or type to steer it. • In CarPlay, ask in a new chat, a recent one or a bot's. On Apple Watch, raise your wrist and ask. • "Hey Siri, ask Redde…" works from the Lock Screen and AirPods, and Siri takes notes for your agent. A control, widget or the Action Button starts listening. • Spoken prefixes add text, switch models or go to a bot: "Opus, review this diff". SEE THE AGENT WORK • Watch reasoning and tool calls live, with a Live Activity; lock the phone and it carries on. The list shows what's working or needs you. • Approve a risky command or answer the agent's question from a notification, out loud, or with a nod in AirPods. Pair your Hermes and notifications arrive with Redde closed, encrypted end to end, and an agent you allow can call you. A FULL CLIENT, NOT JUST A MIC • Chats live in your gateway's session ledger: start on the phone, continue on the desktop or the CLI. Search them, pin, rename, fork, archive, or go incognito. • Projects, scheduled jobs and the Kanban board. • Phone tools: your agent can use your iPhone's calendar, reminders, contacts, photos and files, set alarms, write on a widget, and start calls and texts, each only if you allow it. • Rich replies: Markdown, code, tables, Mermaid diagrams, math, and cards with maps, places and the weather. Pictures, PDFs and audio open in place. • Ask about part of a reply, regenerate, edit and resend, or switch models with /model. • Attach photos, videos, files or a day's calendar, or share from any app. • Skills, tools, plugins, memory and context files; on the server, MCP servers, logs, updates, files and an SSH terminal. YOUR BACKEND, YOUR RULES • Connect to Hermes through the Hermes Dashboard or the Hermes API, on your LAN, over a tailnet, or behind Cloudflare Access, Pangolin or a reverse proxy. Save several servers, see all their chats in one list, and sync them with iCloud. Sign in with a password or a browser. • Or go straight to any OpenAI-compatible endpoint: llama.cpp, llama-swap, vLLM or Ollama on your hardware, or a hosted provider with your key. • Set up by QR code or link. Credentials stay in the Keychain. • Face ID lock, seven themes with your own colors, app icons and voice orbs, iPad split view, iPhone Duo. • The one service we run is an optional relay for notifications, which can't read them. REQUIRES A Hermes agent (github.com/NousResearch/hermes-agent) or an OpenAI-compatible endpoint; bots need Hermes. Redde includes no model and no AI service of its own. Hermes is an open-source project by Nous Research. Redde is an independent client, not affiliated with it.
