BYO key
Use the model you trust.
ShellYard does not need to be the model. ShellYard is the interface between your infrastructure
work and the model you choose — same flow, four providers.
ChatGPT / OpenAI
Bring your OpenAI API key. Choose the model you trust for the work — Magellan is the interface, not the inference.
Claude / Anthropic
Same flow with Anthropic — paste your key, pick a Claude model, work with it inside the terminal.
Gemini / Google
Same flow with Google — paste your AI Studio key, pick a Gemini model, run it inside the terminal.
Ollama / local models
Point Magellan at a local Ollama (or LM Studio / OpenAI-compatible) endpoint and keep prompts and responses on your network.
On Free, your provider key lives in a local AES-256-GCM-encrypted SQLite vault on disk, sealed by your OS keychain
— it never leaves the device. Prompts and responses pass directly between your client and your
chosen provider; ShellYard does not meter, mark up, or proxy AI usage.
