What your collaborator can do.
The companion is the product. These are the things it gives you — privacy, reach, memory, the full tool palette. The hands come later.
Your keys. Your collaborator. Your machine.
Your keys never leave your machine. Your collaborator just knows where to find them. Conversations stay local. Nothing passes through anyone else's hands — not ours, not a proxy, not a middleman.
Privacy Architecture
- macOS Keychain-encrypted credentials
- Conversations stored locally, never on our servers
- No telemetry, no logging, no account required
- Direct connections to your AI providers — no proxy
Every tool your collaborator can reach.
Your collaborator speaks every protocol. MCP servers, Rainfall tools, community servers, your own custom integrations — one palette, every action visible. Watch the work happen step by step.
MCP Integration
- Native MCP client built-in
- Mix Rainfall, MCP, local, and external tools
- Live inline execution status — watch it work
- Automatic tool discovery and registration
Give your collaborator the keys to the sky.
You are not locked into a single provider. OpenAI, Anthropic, Groq, Mistral, DeepSeek, Z.ai, OpenRouter, Moonshot, Hyperbolic, NanoGPT, LM Studio — whatever your collaborator flies with, you choose. Switch models per conversation. Run local models when you need to.
Multi-Provider System
- Plug in OpenAI, Anthropic, Groq, Mistral, DeepSeek, Z.ai
- OpenRouter, Moonshot, Hyperbolic, NanoGPT, Grok/xAI
- Custom OpenAI-compatible endpoints
- Local models supported via LM Studio
Summon your collaborator from anywhere.
Cmd+Shift+R and they are already paying attention. The menu bar hides them when you do not need them. Anywhere you are in the workflow, your collaborator is one keystroke away.
Power User Features
- Global hotkey: Cmd+Shift+R
- Menu bar integration

Surfaces for technical thinking.
KaTeX math. Wrapped tables. Syntax-highlighted code with automatic language detection. Your collaborator's responses render as documents you can read, scan, and copy — not chat bubbles you scroll past.
Advanced Markdown
- KaTeX math expression support
- Responsive table wrappers
- Code blocks with language detection
- Copy-to-clipboard for code snippets
One palette. Every provider.
Your collaborator flies with whatever you choose. No lock-in. No funnel. The keys are yours.
Begin.
Free. Your collaborator lives on your machine. When you want them to have hands — edge nodes, a fleet, always-on capabilities — that's when you upgrade.
