What you get
Instant, easy-to-read insights across 15 focused "labs."
Clear notes, gentle tweaks, zero judgment.
Your Color Season
Your personal palette decoder for beauty. We analyze undertone, depth, clarity, and contrast to place you in one of the 12 color seasons, then turn that into makeup colors that do the heavy lifting.
Shade Match on Camera
Cam-ready shade check for video. Matches foundation to jaw/neck and previews how it behaves under ring lights, warm desk lamps, and auto white balance–no more floating head.
Makeup Flashback
The anti-ghost test. We simulate flash to spot white cast from SPF or silica/HD powders on high points before your pics say 'boo.'
Is the Coverage Right?
Skin vs screen, peacefully negotiated. Finds the sweet spot so texture looks intentional, not masked–whether it's daylight, office LEDs, or studio flash.
Do Pores Stand Out?
T-zone truth check. Zooms the nose and inner cheeks to see if pores are blurred, neutral, or starring in a close-up, then suggests finish tweaks.
Dry Patches & Cakiness
Tiny issues that go big on camera. Flags dry patches, cakey buildup, and foundation catching on peach fuzz so your base reads chic, not chalky.
Does It Transfer?
Makeup belongs on your face, not your clothes or phone. We spot transfer risk and show how to lock it down.
Jawline & Neck Blend
Blend border control. Scans the face perimeter, jaw, and neck for demarcation and color jumps; shows exactly where to feather and match.
Will It Last?
Will it last? We read shine breakthroughs, separation at nostrils/chin, fading blush, and mascara migration to estimate staying power.
Does It Turn Orange?
Sunset-proof your base. Compares fresh vs later wear and previews warm magic-hour light so you glow honeyed, not orange.
Is Makeup Symmetrical?
Symmetry, but make it chic. Checks brow tails, wing angles, lash placement, and lip outline so both sides sing the same chorus.
Contour Placement
Smart sculpting for your face shape. Verifies contour under the cheekbone, balances temple/jaw, and places highlight on true high points–sculpt, not stripes.
Highlighter Placement
Glow without the texture tax. Audits highlight and sparkle so they kiss high planes without spotlighting pores or fine lines.
Any Harsh Edges?
The gradient audit for eyes and cheeks. Compares soft diffusion vs stampy edges so blends look editorial.
Does It Crease?
Wrinkle whisperer for lids and under-eyes. Spots product settling–especially on hooded, mono, or deep-set eyes–and suggests quick fixes.

How siOsi Makes Money
siOsi is built and run by the small team you'll meet below, based in Europe. No investors, no ad network.
Every analysis runs through fifteen labs — twelve for makeup, three for face geometry — before you see a single verdict.
siOsi makes money two ways: subscriptions at /pro, and commissions when you buy through a shop link on your results. Commissions never change which products get recommended or how — the verdicts don't care what pays.

Frequently asked questions
What is siOsi?
siOsi is a free AI tool that reads a single selfie to give you a complete color and makeup analysis: your 12-season color type, undertone, gold-vs-silver verdict, and personal palette, plus 15 makeup diagnostic labs. No signup for your first analysis, in 9 languages.
How does siOsi work?
Upload one photo. siOsi uses vision models and facial-landmark detection to read your skin, hair, and eye color, undertone, depth, and contrast, then maps them to the 12-season system and grades your makeup across 15 labs – each result with a confidence score, in about 60 seconds.
Is siOsi accurate?
Accuracy depends on your photo. A clean, well-lit, natural-light selfie without filters or heavy makeup gives the most reliable read. siOsi flags low-confidence photos so you know when to retake, and shows a confidence score with every result rather than a single guess.
How is siOsi different from other color analysis tools?
Most tools are self-report quizzes or a single makeup filter. siOsi reads your actual photo and does both halves – full 12-season color analysis and 15 technical makeup labs – in one free tool. In-person analysis costs $200–$800 and analysts often disagree; siOsi gives a steadier read in seconds.
Is my photo private?
Your photo is uploaded over HTTPS and processed to produce your analysis. siOsi does not sell your photos or use them to train models. See the privacy policy for full retention and deletion details.
