❓ Frequently Asked Questions

Face-K keeps celebrity matching as the familiar entry, then moves to a personal report format:

• Step 1: Upload your photo - the AI automatically finds your face
• Step 2: The AI analyzes your facial features like face shape, eyes, nose, and more
• Step 3: Your features are compared with our curated Korean celebrity roster
• Step 4: Your top match appears first, and report actions for save/share follow.

The whole process takes just a few seconds, and this rollout is designed to add stronger report value before any new roster expansion.

The report combines: 1) match candidate order, 2) similarity score context, 3) suggested next actions (save or share).

We are shipping this before expanding the public catalog, so the existing match journey stays stable first.

The accuracy depends on your photo quality:

• Good lighting: Clear, bright photos work best
• Face clearly visible: Make sure your whole face is in the photo
• Look at the camera: Front-facing photos give better results

Remember, this is for entertainment! The AI finds similarities in facial features, not exact lookalikes.

It uses your solar-calendar birth date, birth time, gender, selected birth region, uploaded-photo lookalike match result, and expression mood. Birth region supports Korea and major overseas regions, with optional browser-based auto selection.

The detailed GPT interpretation does not send the original photo. It sends only structured Saju calculation results, expression mood, and the matched celebrity snapshot.

No. The Saju report uses only expression mood from the photo, and it does not store or display race, ethnicity, age, or gender inference results.

The AI looks at many facial features:

• Face shape (oval, round, square, etc.)
• Eye shape and spacing
• Nose shape
• Mouth and lip shape
• Cheekbones and jawline
• Overall face proportions

Different photos can give different results due to lighting, angle, and expression. Try uploading a few photos to see!

The score shows how similar your facial features are to the celebrity:

• Lower score = More similar: A score closer to 0 means you look more alike
• Higher score = Less similar: A higher number means less resemblance

Most matches range from 0.4 to 1.2. Scores under 0.6 indicate strong similarity!

Your privacy is important to us:

• Temporary only: Photos are stored temporarily just to process your match
• Auto-deleted: All uploaded files are automatically deleted within 7 days
• Not used for training: Your photos are never used to train our AI
