Recommended AI for language learning

I've been working on reading and writing and using ChatGPT to double check. I noticed it's not very accurate sometimes. Is there any AI you recommend that would be better? I was thinking of trying Deepseek but wasn't sure if there might be anything else. I'm not writing anything serious. Just chatting with my parents and some bi-lingual friends who are helping me study. I chat with my parents in colloquial Cantonese.
