Add your first API key

1. In the workspace, open API keys from the top bar.
2. Pick a provider, for example OpenAI, Anthropic or Google.
3. Click Get a key to open that provider's dashboard, create a key and copy it.
4. Paste it into MultiScreenAI. The key is checked immediately and the models it can use appear in the model menu.

One key is enough to start. A single OpenRouter key reaches hundreds of models from most labs.
