Over-reliance on direct translation leads to plateaus

Learners rely heavily on translation based exercises, which limits vocabulary recall and makes it hard to form sentences independently.

When they finally encounter real world conversations, anxiety takes over—not because of the other person, but because of fear of forgetting words, sounding incorrect, or being judged.

Prompt-Driven Conversation with Friends

From Solo Practice to Shared Conversation

From Solo Practice to Shared Conversation

Instead of practicing alone or chatting with an AI bot, learners are paired with a friend and practice through shared conversation quests. Practicing with someone familiar creates a sense of comfort that lowers fear of judgment, making learners more willing to take risks, make mistakes, and keep going—all essential for progressing toward conversational fluency.

An AI-generated prompt kicks off the conversation so no one has to “go first,” helping both participants ease into natural conversation while staying focused on recall.

Learners can practice together even when studying different languages.

Grey text indicates the learner’s target language, while contextual translation logic preserves idioms and intent rather than relying on direct word for word translation.

There are many differing complexities between languages. I thought the way Google Translate's NTM handled this best by not only translating word by word for complete context, but also replacing idioms and filler words with similar ones in the translated language.

My biggest takeaway from a project on a science-back platform was to consciously research and consistently ask myself of the intention behind my designs. I'd love to chat about an in-depth case study!
