Custom Translation Services

For AI providers that do not appear in the built-in service list, Doco Translate lets you add a custom service and connect it for translation.

Add a Custom Service

Open the Doco Translate Settings → Services panel. Click Add Custom Service below the service list, enter a service name, and choose an API protocol.

API Protocols

Doco Translate supports five common AI API protocols:

1. OpenAI protocol (Chat Completions)
2. Anthropic protocol (Responses)
3. Gemini protocol
4. Ollama protocol
5. LM Studio protocol

Custom Request Parameters

Doco Translate supports the following custom request settings:

• API host: useful when switching between standard APIs and Coding Plan endpoints
• API path: use a non-standard path supplied by a third-party provider
• Request body parameters: configure options such as disabling reasoning, which is recommended for translation
• Request headers: use additional headers in special cases

Custom Prompt

Doco Translate includes this default prompt:

Translate the input text into {{TARGET_LANGUAGE}}.

INPUT:
{{TEXT}}

Click Edit Prompt to change the prompt and adjust the model's translation style or output. Keep the {{TARGET_LANGUAGE}} and {{TEXT}} placeholders because Doco Translate replaces them with the target language and input text.
