Language Reactor

Language Reactor is an AI chat bot tool that chats with Aria, a virtual conversation partner for language practice. An AI conversation partner called Aria that lets language learners practise a target language by chat, with an English fallback for phrases they cannot yet produce and optional voice input via the dictionary button.

Language Reactor's Chatbot puts a virtual conversation partner named Aria in front of you and lets you practise a target language in writing. The chat screen asks you to pick a study language and a native language, then opens a conversation. If you cannot produce a phrase in the language you are learning, you can type it in English and Aria works with that, which lowers the barrier for learners who freeze at the first sentence. A dictionary button sits next to the chat, and holding it starts voice recording, so spoken input is an option alongside typing. The tool is built for learners who want low-pressure speaking and writing practice without booking a tutor. Aria is framed as a conversation partner rather than a grammar drill: the homepage offers themed entry points such as Famous People, Psychologist, Games and Situations, plus a plain Just Aria mode for open conversation. Those themes give a session a shape, which helps when a learner has no idea what to talk about. Aria also remembers earlier conversations, and those memories can be reviewed in Settings, so a returning user is not starting from zero every time. The chatbot is one part of a wider Language Reactor toolbox. The same account also reaches Media (learning from Netflix and YouTube), PhrasePump, and Saved items, so chat practice sits alongside immersion in native content rather than replacing it. Put against standalone AI chat companions, the draw here is the surrounding study system and the English fallback for stuck moments. Put against a human tutor, the trade-off is obvious: no correction of pronunciation, no lesson plan, and no accountability beyond what the learner brings. The homepage does not publish prices or plan limits. Persistent memory of past conversations is marked as a Pro feature, which indicates a paid tier exists above the free experience, but the details of that tier are not stated on this page. Learners should expect to sign in to use the chatbot and to check Pro mode for what memory and other extras cost.
