Student Assistant
Chista, an AI assistant made for schoolchildren, that grows up with each student and gets to know them.

Chista is an AI assistant made for students, and I designed its experience end to end, from the first user flow to the last interface part. Instead of one conversation for everyone, it has three school stages, characters that grow with the user, more than forty subjects with their own emblems and a five-step questionnaire, so that every answer belongs to the student reading it.
