How configuration works
1. Generate an API key
Create a key in your provider's console. We list direct links for each provider in the docs.
2. Paste it in admin settings
Go to Admin → Translation providers. Keys are encrypted at rest with AES-256-GCM.
3. Pick a provider per project
Each project chooses its provider. Override the model with a free-text field — models evolve too fast to hardcode.
