Project Overview
History
He@lio was our first project was born during the early stages of the pandemic, addressing the rising mental health challenges. The idea of a mental health chatbot emerged from a storytelling session on AI by local entrepreneur Chad Oda. The entire design was ideated by youth, who took on the challenge of learning computer science at an early stage all by themselves. We tried Microsoft Virtual Agent to create the first chatbot. Followed by conversational AI programming playing with Voiceflow. Last year we graduated to ChatGPT based API that learnt from our journaling data.
Started by Bellevue Youth Link's Mental Health subgroup, ideated the text chatbot based on Microsoft Virtual Agent.
Migrated from text to a conversational AI program called "Voiceflow".
Adapted ChatGPT and moved on to the 3rd iteration.
Applied to NSF (National Science Foundation) & qualified as "Human-centric design," moving on to the next stage.
