Knowing ourselves.Caring for one another.

Many people arrive at OpenJung with a simple question: what is my personality type? We offer a free way to explore that question, with access to the questionnaire’s source, scoring rules and limitations. But four letters are not a complete account of a person.

We want there to be room after the result to reflect. You might record a conversation that felt difficult, notice a description that does not fit, or choose a small action to try. The point is to return to your own experiences, not to make them fit a type. OpenJung is not the official MBTI assessment, and its current adaptation, quick test and translations do not have published validation studies.

That is the starting point for our wider work: make it easier to begin exploring, while leaving space for uncertainty and for people to decide what matters to them.

PurrJung is the cat observation project in the OpenJung family, with its own website and watercolor identity. Its 16 everyday behavior questions invite you to notice when your cat approaches, how it plays and where it rests. “Not observed” is a valid answer; you do not have to guess to complete a portrait.

The portrait is a playful starting point, not a scientifically validated classification or a veterinary assessment. Observation notes and repeat observations give you somewhere to record context and change. They should not turn an unexpected change in behavior into “just its personality”; health concerns belong in a conversation with a veterinarian.

The longer-term purpose is responsible care. Before bringing a cat home, consider time, space, costs and what happens if your circumstances change. If care becomes difficult, seek help rather than abandon the animal. PurrJung’s responsible-care, health and community-cat resources serve that purpose. Beyond the cats in our homes, we want the welfare of cats and other small animals to be taken seriously, so they can live alongside people. Its TNR resources discuss both the possibilities and limits of trap–neuter–return, rather than presenting it as a universal solution.

Open ADHD is our free project for adults exploring attention and daily life. You might be finding it hard to start a task, losing track of what you meant to do, or trying to explain a recurring difficulty at a healthcare appointment. You can begin with that situation, without first completing a questionnaire or having a diagnosis.

The site offers a five-minute task helper, a journal and appointment notes, alongside learning resources. For example, instead of writing “finish the report,” you could choose “open the document and write a heading” as a first action. This is an example of using a tool, not a promise of treatment or a task prescribed by a personality type. Many everyday tools currently have English and Simplified Chinese versions; language coverage differs across the site.

The main 18-question reflection is an original questionnaire, not the ASRS, and has not been independently clinically validated. It summarizes reported answer frequencies; it cannot diagnose or rule out ADHD, identify a subtype, estimate probability or assign clinical severity. If difficulties affect daily life, seeking qualified professional help does not depend on a questionnaire result. Answers and health notes stay in the current browser and are not uploaded; hosting and limited visit analytics are separate matters explained in its privacy policy.

Personality exploration, cat observation and ADHD-related support address different needs. Bringing them into the same family does not mean treating them as one theory. A personality type cannot explain ADHD, and human personality labels cannot establish what a cat needs.

Our shared vision is to make understanding more accessible, and to connect that understanding with care in everyday life. For OpenJung, that means space for reflection beyond a result. For PurrJung, it means responsible care without abandonment and concern for other animals. For Open ADHD, it means practical support and clearer ways to describe difficulties and ask for help. These are aims we work toward, not outcomes a website can guarantee.

That also asks something of how we build. Explain what a tool can and cannot tell you. Make language and accessibility part of the work. Show sources and leave a way to correct mistakes. Let people understand where their records go before they choose to share them. We would rather make one useful action easier than add another label to someone’s life.

The three projects keep their own sites, visual identities and data rules. Sharing a brand does not mean sharing health records or having identical licenses. OpenJung publishes its code; PurrJung’s source is private. Use each project’s own privacy, methodology and licensing information rather than assuming one policy covers the whole family.

You do not need to use all three sites. If you came to explore yourself, write down one real experience rather than taking another test. If you care for a cat, observe it without interrupting it, or read the preparation checklist with someone considering adoption. If something feels hard to begin today, choose one small action in Open ADHD; if you are preparing for an appointment, organize the examples you want to discuss.

You can also point out an unclear sentence, suggest a translation or share a relevant public guide with someone who wants it. There is no need to send personal results or health records. A more caring daily life takes more than a website; these projects are the part we can keep working on.
