<p id="ai-app-translate">The <em>translate</em> app is one of the apps that provide machine translation functionality in Nextcloud and act as a translation backend for the <a class="reference internal" href="app_assistant.html#ai-app-assistant"><span class="std std-ref">Nextcloud Assistant app</span></a>, the <em>text</em> app and <a class="reference internal" href="overview.html#mt-consumer-apps"><span class="std std-ref">other apps making use of the core Translation API</span></a>. The <em>translate</em> app specifically runs only open source models and does so entirely on-premises. Nextcloud can provide customer support upon request, please talk to your account manager for the possibilities.</p>
<p>The app currently supports the following languages:</p>
<ul class="simple">
<li><p>English (en)</p></li>
<li><p>German (de)</p></li>
<li><p>French (fr)</p></li>
<li><p>Spanish (es)</p></li>
<li><p>Chinese (zh)</p></li>
</ul>
<p>As the models are entirely open source, the quality of translations may not be comparable to commercially available machine translation services.</p>

<h3>Setup<a class="headerlink" href="#setup" title="Link to this heading"></a></h3>
<p>After installing this app you will need to run:</p>

<p>Positive:
* the software for training and inference of this model is open source
* the trained model is freely available, and thus can be run on-premises
* the training data is freely available, making it possible to check or correct for bias or optimise the performance and CO2 usage.</p>

<section id="known-limitations">
<h2>Known Limitations<a class="headerlink" href="#known-limitations" title="Link to this heading"></a></h2>
<ul class="simple">
<li><p>Language models are likely to generate false information and should thus only be used in situations that are not critical. It’s recommended to only use AI at the beginning of a creation process and not at the end, so that outputs of AI serve as a draft for example and not as final product. Always check the output of language models before using it.</p></li>
<li><p>Make sure to test the translation model you are using it for whether it meets the use-case’s quality requirements</p></li>
<li><p>Language models notoriously have a high energy consumption</p></li>
<li><p>Customer support is available upon request, however we can’t solve false or problematic output, most performance issues, or other problems caused by the underlying models. Support is thus limited only to bugs directly caused by the implementation of the app (connectors, API, front-end, AppAPI)</p></li>
