**LanguageTool** is a multilingual grammar, style, and spell checker that supports more than 20 languages. According to their privacy policy, they do not store any content sent to their service for review, but for higher assurance the software is [self-hostable](https://dev.languagetool.org/http-server).
LanguageTool offers integration with a variety of [office suites](https://languagetool.org/services#text_editors) and [email clients](https://languagetool.org/services#mail_clients).
**LibreTranslate** is a free and open-source machine translation web interface and API server. It uses [Argos Translate](https://github.com/argosopentech/argos-translate) models on the backend for translations.
You can use LibreTranslate through a number of public instances, with some that offer a [Tor](tor.md) onion service or an [I2P](alternative-networks.md#i2p-the-invisible-internet-project) eepsite. You can also host the software yourself for maximum control over the text submitted for translation.
We use a self-hosted instance of LibreTranslate to automatically translate posts on our [forum](https://discuss.privacyguides.net) to multiple languages.
