Give your readers something to do. RealSmile drops a free, interactive face-analysis quiz straight into any post or page — visitors upload a photo and get an instant, measurement-based face rating, and they stay on your site the whole time. No API key, no account, no server costs. Just one shortcode.

It’s the kind of interactive content — a “how old do I look” quiz, an attractiveness test, selfie score, face symmetry check, or looksmax analyzer — that lifts time-on-page, shares, and return visits on beauty, grooming, dating, fitness, and self-improvement blogs. Think of it as an engagement widget that turns a passive read into a share-worthy result.

Six widgets, one shortcode:

[realsmile_widget type="looksmax"] — looksmaxxing test: 17-metric face analysis (symmetry, canthal tilt, jawline angle, golden ratio and more)
[realsmile_widget type="age"] — NEW: “how old do I look?” age guesser (an honest age range, never a fake-precise number)
[realsmile_widget type="smile"] — smile analyzer (Duchenne / genuine-smile detection)
[realsmile_widget type="golden-ratio"] — golden ratio face measurement
[realsmile_widget type="face-score"] — quick 0–100 face score
[realsmile_widget type="rank"] — photo ranker (compare 2–6 photos, pick the best)

Why embed it:

More engagement — an interactive quiz keeps readers on the page instead of bouncing; results are made to share
Zero setup — no API key, no account, no server costs; it’s a single shortcode
Zero page-speed cost — loads lazily in a sandboxed iframe, so your Core Web Vitals are unaffected
Measurement-based, not a novelty quiz — the underlying impression model is validated, with published methodology (see below)
Privacy-first — photos are processed in memory and deleted instantly; never stored, never used for training

Validated accuracy (and its honest limits):

The Face Score impression model behind these widgets was tested against a 5,500-face academic benchmark of human-rated photos, where its predictions correlate with averaged human ratings at r ≈ 0.8 — strong agreement by social-science standards. The full methodology is published at https://realsmile.online/research-base. That validation applies to the impression score specifically: the geometric measurements are honest rulers (not attractiveness verdicts), and the new age widget is an experimental photo read that always shows a range, never a fake-precise number — the widget itself says so.

Perfect for:

Beauty, skincare & makeup blogs — a “rate my features” quiz readers love to share
Men’s grooming & looksmaxxing sites — the full looksmaxxing test, on your own domain
Anti-aging, skincare & wellness content — a “how old do I look?” quiz is the perfect interactive hook
Dating & relationship blogs — a photo ranker for “which profile picture wins?”
Fitness, glow-up & self-improvement content — an interactive before/after hook
Any publisher who wants quiz-style interactive content without building one

Options:

height — iframe height in pixels (default 720): [realsmile_widget type="smile" height="640"]
badge — a small visible “Free face analysis by RealSmile” credit renders under the widget by default; set badge="no" to hide it

External Service Disclosure

This plugin embeds an iframe served by realsmile.online (the RealSmile face-analysis service). The iframe loads only on pages where you place the shortcode. When one of your visitors chooses to upload a photo inside the widget, that photo is sent to RealSmile for analysis, processed in memory, and deleted immediately after the facial landmarks are measured — it is never written to disk, never stored, and never used to train anything. No data is collected by the plugin itself, and nothing is sent anywhere until a visitor actively uses the widget.
