Frequently Asked Questions (FAQ)

Q. Are the analysis results accurate?

AI analysis shows high accuracy, but results may vary depending on lighting, angle, expression, makeup, etc. Please use it for fun and reference, and do not use it as medical or legal evidence.

Q. Are uploaded photos saved?

Q. What file formats are supported?

JPG, PNG, JPEG formats are supported. File size is up to 10MB, and high-quality images of about 1-5MB are recommended for optimal analysis.
