Frequently Asked Questions

Check out questions about the HTP test.

Q1. Is the HTP test accurate? Can I trust it?
The HTP (House-Tree-Person) test is a verified projective test used since the 1940s. It has been used in clinical settings worldwide for over 70 years.

However, this service is a 'tool for self-understanding', not a professional medical diagnosis. If psychological difficulties persist, we recommend professional counseling.
Q2. Is the AI analysis accurate?
GPT-5.5 is a state-of-the-art AI model also used in the medical field. Prompts were designed based on expert know-how and follow standard HTP interpretation criteria.

However, AI is an auxiliary tool, and professional counseling is more suitable for complex psychological states.
Q3. Is it okay if I can't draw well?
No problem at all!
The HTP test does not evaluate drawing skills. How you express and what you draw is important. However, if you draw too simply, there may be limitations in analysis.
Q4. Can I use an eraser when drawing?
Yes, you can use it.
Using an eraser itself can be information, but drawing comfortably is the most important.
Q5. Do I have to color it?
It's optional.
You can draw with just a black pen or pencil, or use colored pencils. Please draw in a comfortable way.
Q6. How detailed should I draw?
There is no right answer.
It's okay to draw simply or in detail. Please draw naturally as it comes to mind.
Q7. Can I take the test multiple times?
Yes, it is possible.
However, if you do it multiple times on the same day, you may be influenced by the first test. It is good to check for changes with an interval of at least 2 weeks.
Q8. Should I answer the questions honestly?
Yes, the more honest you are, the more accurate the analysis will be.
Answers are strictly confidential, and there are no right or wrong answers. Please answer as you feel comfortable.
Q9. Can I save the results?
Yes, possible:
- PDF Download
- Save to account (when logged in)
- Screenshot capture
Q10. How long is the data kept?
It is automatically deleted after 90 days of storage by default.
You can delete it immediately at any time if you wish.
Q11. The result seems different from me
There are several possibilities:
- Your current state may be different from usual, or unconscious parts may have been reflected
- It may be a limitation of AI interpretation. Please use it as reference material, and we recommend receiving counseling if professional counseling is needed.
Q12. Can this test diagnose a disease?
No, it is not a diagnostic tool.
This is an 'exploratory tool' to help self-understanding.
Medical diagnosis must be consulted with a specialist.
The HTP test analyzed by AI is a 'first step' or 'auxiliary tool', not a substitute for hospital examination.
