Cipher AI runs powerful language models directly on your iPhone. No cloud. No data collection. No one reading your conversations.
Most AI apps send everything to the cloud. Cipher doesn't. Your conversations stay on your device, processed by powerful models running entirely locally.
Cipher runs powerful language models directly on your device. No cloud, no servers, no middlemen — just fast, private AI that's always in your control.
Create autonomous AI agents that browse the web, research topics, write code, and automate complex tasks — running 24/7 on your own hardware via LMBridge.
Connect Cipher to large models running on your Mac, PC, or Linux machine via LMBridge. Frontier-scale inference without paying per token. Works from anywhere — no same-network requirement.
Go beyond chat. Cipher includes a built-in MCP tool store with 45+ integrations — giving your AI the ability to run commands, query databases, browse the web, connect Slack, GitHub, Notion, and more.
No setup needed. These tools are available in every conversation, running entirely on your device.
Connect Cipher to the tools you already use. Every MCP server runs on your machine via LMBridge — your data never touches a third-party cloud.
Plus: Sequential Thinking, Memory, ArXiv Papers, YouTube Transcripts, E2B Sandbox, and more. Add any custom MCP server.
See the model reason step-by-step before answering. Full support for DeepSeek-R1 and other reasoning models.
Responses appear word-by-word as the model generates them. No spinner, no waiting.
Download a model once and it works forever — airplane mode, no signal, no problem.
Set agents to run daily briefings, stock alerts, research reports, and more — automatically on a cron schedule.
Background the app, come back later — Cipher picks up the LMBridge connection right where you left off.
No usage analytics, no conversation logging. The developer literally cannot read your chats.
LMBridge is a lightweight desktop app you install on your computer. It connects your local LM Studio or Ollama models to Cipher over a secure WebSocket — so you can run a 70B model from anywhere.
Pair Cipher to your computer with a 6-digit PIN. Model weights never leave your machine — only tokens are relayed. Works from any network.
Install LMBridge on the machine running LM Studio or Ollama, then pair it with Cipher on your iPhone using a 6-digit PIN. Available for macOS, Windows, and Linux.
Double-click the downloaded file. Drag Cipher LMBridge into your Applications folder.
macOS may show a security warning on first launch. Go to System Settings → Privacy & Security and click Open Anyway. This only happens once.
Open LM Studio and enable the local server (default port: 1234), or start Ollama which runs on port 11434. Load the model you want to use.
Open the app from your Applications folder. It connects to LM Studio or Ollama automatically and displays a 6-digit PIN in the menu bar.
In Cipher, go to Settings → LMBridge → Add Server. Enter the PIN shown on your computer. You're connected — your models will appear in the model picker.
Double-click the .exe and follow the setup wizard. LMBridge installs to Program Files and adds a Start Menu shortcut.
You may see a SmartScreen prompt on first run. Click More info → Run anyway. The app is safe — SmartScreen warns about any unsigned new app.
Open LM Studio and enable the local server (port 1234), or run Ollama (port 11434). Load your model of choice.
Start the app. It appears in your system tray and displays a 6-digit PIN to share with Cipher on your iPhone.
In Cipher, go to Settings → LMBridge → Add Server and enter the PIN. Your models will appear instantly in the model picker.
Pick the right architecture for your system — x64 for most desktops, ARM64 for Raspberry Pi and ARM servers.
chmod +x "Cipher LMBridge-1.1.0.AppImage" then double-click or run from terminal. No installation needed.
Open LM Studio (port 1234) or Ollama (port 11434). Load the model you want to use.
LMBridge displays a 6-digit PIN in the system tray. Enter it in Cipher under Settings → LMBridge → Add Server.
