Everyone's Diagnostic Chart

"Everyone's Diagnosis Chart" is a web service where anyone can freely create, publish, and share original diagnosis charts.

Whether you want to "find something that suits you" or "create an original personality diagnosis or character diagnosis," you can easily realize these ideas through a flowchart-style diagnosis.

Main Features

① Anyone can enjoy diagnoses with ease

As you progress through the chart by answering questions, you'll reach results tailored to your answers. You can enjoy a wide variety of diagnoses across different genres—personality diagnoses, character diagnoses, hobbies, and practical life advice diagnoses.

② Create diagnoses without programming

You can create original diagnosis charts by freely setting questions, choices, and diagnosis results, then simply connecting nodes together. It supports not only Yes/No formats but also multiple choices and complex branching.

③ Freely customize chart design

You can adjust the layout of questions and results, colors, connection lines, and more to design your own unique diagnosis chart. Creation and editing are possible not only on PC but also from smartphones.

④ Publish and share your created diagnoses

Diagnoses you create can be published online and shared on SNS like X using a dedicated URL. You can not only enjoy them yourself but also let friends and many others play with them.

Development Background and Commitment

We completely renovated a diagnosis chart creation site we previously operated, from its features and design to its system architecture.

What we particularly focused on was providing not just the "fun of playing" diagnoses but also the "fun of creating" them.

We implemented a visually operable chart editor so creators can freely design question placement, branching, and appearance. We also aim for a UI that's easy to operate on smartphones.

Technical Stack

The frontend uses React (Vite), while the backend, database, and authentication infrastructure use Supabase, and the distribution platform uses Cloudflare.

As a personally developed service, we aim to create a platform where anyone can easily create and share diagnoses while keeping operational burden and costs low.

Please try playing with diagnoses or creating your own diagnosis chart!
