How configuration works

  1. 1. Generate an API key

    Create a key in your provider's console. We list direct links for each provider in the docs.

  2. 2. Paste it in admin settings

    Go to Admin → Translation providers. Keys are encrypted at rest with AES-256-GCM.

  3. 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.
