There are 2 ways of translating content in Discourse. The translator plugin and the ai plugin.
The Discourse Translator plugin supports LibreTranslate. The AI plugin supports AI-powered translation, using LLMs like Gemini, for example.
What kind of “wiring” or integration do you want to see in the translator plugin that you like in the ai plugin?
Note that the translator plugin is end-of-life and won’t receive updates.
