What did USDC settle at today? Check the web and give me one line.

Everything on the board.
Local models welcome
Point Nexus at Ollama and your own hardware answers beside the cloud — tool calling included, no key needed.
Real tools, every model
Web search and page fetch are built in; wire any MCP server for more. Every model gets hands, not just words.
A terminal inside
An embedded terminal runs Claude Code without leaving the deck. Chat on one side, ship on the other.
Costs on instruments
Live token and dollar readouts per reply, 30-day spend per provider, automatic fallback when a route fails.
Yours to theme
Accent colors, sounds, voice input and read-aloud, tray autostart. Chats auto-save to your machine — nowhere else.

Questions, answered.
Where do my API keys live?
In your operating system's keychain — Windows Credential Manager on Windows. Never in plain files, and never sent anywhere except directly to the provider you're calling.
Does Nexus work offline?
With local models through Ollama, yes — chat runs entirely on your machine. Cloud providers need a connection, and your license key itself activates offline.
Which models can I use?
Anything your keys unlock: GPT, Claude, Gemini, Mistral, Groq, DeepSeek and 40+ more providers, plus any model you run locally with Ollama.
What happens when the trial ends?
Chat locks until you add a license key. Nothing is deleted — your conversations, keys and settings stay on your machine and unlock with the key.
Do I need an account?
No. There's no signup and no telemetry. A license is a signed key that activates offline — buy it, paste it, done.
How do updates arrive?
Nexus checks for new releases and installs updates from inside the app — one click on the status bar when a new version lands.
