# Improve Translation Accuracy

Three ways to get better translations out of iTranslator.

A translation can sometimes be less accurate than expected. Here is why, and what you can do about it.

## 1. Provide a source language <a href="#id-1.-provide-a-source-language" id="id-1.-provide-a-source-language"></a>

The source language is optional. When it is missing, iTranslator detects the language of each message before translating it. The detection can occasionally be wrong, and the translation with it.

If the messages of a channel are always written in the same language, **set it as the source language** of your configuration. In the dashboard it is the **Source Language** field of an [Auto-Translate](/amazing-features/automatic-translation.md) or [Role-Translation](/amazing-features/role-translation.md) configuration.

## 2. Use longer sentences

Very short messages give little information about the language they are written in, so the free translation engine may misdetect it. When you cannot set a source language, a longer sentence helps iTranslator understand which language you speak.

This is rarely needed with Premium, whose translation engine is much more accurate.

## 3. Subscribe to Premium

[iTranslator Premium](/overview/premium.md) gives your server a more powerful translation engine, with a much better accuracy and all 109+ languages instead of 30. [Pro AI](/overview/premium.md) goes one step further with an AI engine, and with [Conversation Mode](/amazing-features/conversation-mode.md), which translates consecutive messages together to keep the context.

## Good to know

* [Text-Replacement](/amazing-features/text-replacement.md) expands abbreviations and protects brand names before the translation.
* On a Pro server, the **Smart** [Translation Mode](/amazing-features/translation-mode.md) gives the most accurate translations.
* You can [keep words or sentences untranslated](/fundamentals/ignore-content-and-channels-in-translations.md).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.itranslator.app/fundamentals/improve-translation-accuracy.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
