# Setting Up API Keys

To use AI translation you need an API key from at least one provider. Enter your key in **Settings → AI Settings**.

### Supported providers

| Provider                              | Where to get a key                                                   |
| ------------------------------------- | -------------------------------------------------------------------- |
| **OpenAI**                            | [platform.openai.com/api-keys](https://platform.openai.com/api-keys) |
| **Anthropic (Claude)**                | [console.anthropic.com](https://console.anthropic.com)               |
| **Google (Gemini)**                   | [aistudio.google.com/apikey](https://aistudio.google.com/apikey)     |
| **Grok (xAI)**                        | [console.x.ai](https://console.x.ai)                                 |
| **Mistral AI**                        | [console.mistral.ai](https://console.mistral.ai)                     |
| **DeepSeek**                          | [platform.deepseek.com](https://platform.deepseek.com)               |
| **OpenRouter** (200+ models, one key) | [openrouter.ai/keys](https://openrouter.ai/keys)                     |
| **Ollama**                            | No key needed – runs locally                                         |

### Entering a key

1. Open **Settings → AI Settings**
2. Select your provider from the **Provider** dropdown
3. Paste your API key into the **API Key** field
4. Click **Test Connection** to verify
5. Save settings

Keys are stored locally and are only sent to the provider's own API endpoint.

### Switching providers

You can configure keys for multiple providers in the same settings panel. Switch between them without re-entering credentials – the key for each provider is remembered independently.

### Using Ollama (no key required)

Ollama runs models entirely on your machine. No API key or internet connection is needed.

See [Ollama Setup](/help/ai-translation/ollama.md) for download and configuration instructions.

### Using OpenRouter (one key for everything)

If you prefer not to manage multiple accounts, OpenRouter lets you access 200+ models from all major providers with a single API key. Create an account at [openrouter.ai](https://openrouter.ai) and paste your key into the **OpenRouter** provider slot.

### Troubleshooting

| Problem               | Solution                                                             |
| --------------------- | -------------------------------------------------------------------- |
| "Invalid API key"     | Double-check the key; ensure no leading or trailing spaces           |
| "Rate limit exceeded" | Wait a moment, or upgrade your API plan                              |
| "Model not found"     | Check the model name in settings; it may have been updated           |
| No response           | Check your internet connection and that the provider's service is up |
