MBTI × Generative AI Experience App
DiscontinuedJun 2024 — Aug 2024 (3 months)
Overview
An experiential web application that combines an MBTI assessment with generative AI. It estimates the user's MBTI type from their answers, then has the AI generate music, images and stories to deliver the result as an experience. I handled everything from planning to development and release on my own.

HerokuThe problem I set out to solve
Issues with conventional MBTI assessment apps:
- • The questions have no context linking them, so users often struggle to answer
- • Fitting yourself into pre-written questions makes it hard to measure your true personality accurately
What I put thought into
Implementing "Story Mode"
- • Users choose a world such as "Horror", "Adventure", "Mystery", or the fully original "Creator"
- • By continually choosing options in situations generated by the AI, users' unconscious values and behaviour patterns surface naturally
How results are produced
The MBTI type is derived with the content of the story taken into account, making the result feel more convincing than a conventional assessment
Technical details
- • Centralised the OpenAI API calls and built a mechanism that handles errors through a separate route
- • Changed the stage of the story according to the previous answers and the question number, improving the quality of the AI's output
Outcome
By adding a story experience to the assessment result, users can accept their own personality in a more natural way.
What I learned
I came to appreciate that designing a user experience is not just about "what UI to build" but about "how to draw out behaviour and honest feelings naturally".
