An AI face shape detector looks at a front-facing selfie and tells you which face shape it's closest to, such as oval, round, square or heart. Most then suggest hairstyles, glasses or beard styles that work with that shape. Ten tools follow in no particular order, from free web checks to phone apps.
Knowing your face shape makes a lot of small decisions easier: which glasses frames to try, what to ask the hairdresser for, how to shape a beard. It used to mean tracing your reflection on a mirror with a lipstick. Now an AI tool does it from a selfie.
The ten tools below are listed alphabetically and in no particular order, and each description comes from the tool's own website or App Store listing. Some are free web checks, some are apps with style ideas, and a couple add a score you may not want.
AI face shape tools side by side
The free plan column comes from each tool's own website or App Store listing, as of Oct 2026. Yes means the page names a free plan or free use, Trial only means a time-limited trial, and Not stated means the page named neither. Check the listing before you subscribe to anything.

Ten face shape detectors for selfies
AirBrush
Best for: Getting one of six face types plus notes on your features, inside a photo editor rather than a standalone app.
Duplichecker Face Shape Detector
Best for: A simple check from one front-facing photo, on a free tool hosted by a plagiarism checker site.
Face Shape: Rating & Analyzer
Best for: People who want a golden ratio beauty score alongside the shape, knowing the result is a rating, not just a shape.
FaceShape.app
Best for: Uploading a photo or trying a realtime camera check in the browser, with no app to download.
FaceShapeDetector.ai
Best for: Checking your face shape in a browser in many languages, handy if English isn't your first language.
Find Your Face Shape
Best for: Hairstyle ideas matched to your face shape, for your next trip to the hairdresser.
Hiface
Best for: Ideas for hair, beard, glasses and makeup in one face shape finder, useful for anyone styling more than one thing.
MyFaceShape
Best for: A daily glow-up plan after the scan, from an app that also scores your key features.
Style AI Face Shape Detector
Best for: Personalised style suggestions from an AI face analysis, if you want ideas beyond the shape itself.
What Is My Face Shape
Best for: Seeing percentages across several shapes, which helps when your face sits between two types.
Shape-only tools and score tools aren't the same
Not every face shape tool stops at the shape. Face Shape: Rating & Analyzer pairs the shape with a Beauty Score from the Golden Face Ratio, and MyFaceShape scores key features too. AirBrush, by contrast, says its tool detects 6 face types: round, oval, oblong, diamond, square and heart.
If you just want a steer on hairstyles or glasses, pick a tool that gives the shape without a rating. A beauty rating isn't style advice, and for teenagers in particular it can do more harm than good.

I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.

Your selfie is personal data
The Information Commissioner's Office quotes the UK GDPR definition: personal data is any information relating to an identified or identifiable natural person. A clear photo of your face is about as identifiable as information gets.
So read what each tool says it does with the photo before you upload, prefer tools that tell you, and never run someone else's face through one without asking them first.
Once you know your face shape, AI color analysis tools show which colors suit you.
Getting a clear result from a selfie
- Face the camera straight on, at eye level.
- Pull your hair back off your forehead and jawline.
- Use even light from the front, not a lamp to one side.
- Keep a neutral expression, because a big smile changes the line of your jaw.
- Try two tools and compare, as plenty of faces sit between two shapes.

My plain advice on face shape detectors
Use a free web tool first and see whether the answer matches what you see in the mirror. If you want style ideas, move to an app that suggests hairstyles or glasses. Skip the beauty scores unless you want one, and check what happens to your photo before you hand it over.

Frequently asked questions
How does an AI face shape detector work?
You upload or take a front-facing selfie, the tool compares the proportions of your face and tells you which shape it's closest to, often with style tips.
What face shapes do these tools detect?
Common types include round, oval, oblong, diamond, square and heart. At least one tool here names those six.
Is it safe to upload a selfie to a face shape tool?
Your photo is personal data under UK GDPR, as the Information Commissioner's Office explains, so check each tool's privacy terms before you upload.
Why do two face shape tools give different answers?
Many faces sit between two shapes, and lighting, hair and angle change the result. Some tools show percentages across shapes, which makes that easier to see.
Is there a free AI face shape detector?
Yes. A couple of tools here name free use on their own page, and others offer a trial, so check the free plan column.
