Golden Ratio Face is a browser-based facial analysis tool that compares three facial proportions against the golden ratio φ (approximately 1.618) and returns an overall harmony score. Hosted at https://pslscale.com/golden-ratio-face as part of the PSL Scale suite, the tool accepts a clear front-facing photograph (JPEG, PNG or WebP up to 10 MB) and reports each measurement as a percentage of closeness to phi, with annotated measurement lines drawn on the original image.
The first measurement is the face height ratio, which compares the upper face (forehead to nose bridge) with the lower face (nose bridge to chin). The second is the eye-to-mouth ratio, comparing the span between the outer eye corners with the width of the mouth. The third is the philtrum-to-nose ratio, comparing total nose length with the philtrum from the nose base to the upper lip. Each ratio receives an individual score; the average of the three becomes the overall harmony score.
Golden Ratio Face uses MediaPipe for landmark detection. The model runs in the browser, so the photo is processed locally and the original image is not stored on the server. The normalized landmark coordinates and image-quality numbers are then sent securely to a selected OpenRouter model that produces a written AI interpretation of the three measurements and their combined score. The result page shows the original photo next to the annotated version with three coloured measurement lines (gold, cyan, pink, purple and green) and a downloadable PNG report.
A free preview shows the user what their report will contain before any credit is charged. Each completed report costs 10 credits on the PSL Scale credit system. The tool is positioned for anyone curious about facial proportions, including beauty enthusiasts, content creators, makeup artists, photographers, and people who want a structured way to discuss facial balance. Golden Ratio Face is clear that a higher score only means the measured ratios sit closer to phi in that photograph — it is not a verdict on attractiveness.

Explore AppADHD Test - a research-backed ASRS v1.1 screener with an optional AI personalized report.
ADHD Test ADHD Test shows how a focused web tool can take a respected clinical instrument and make it approachable for everyday adults. The product is built around the ASRS v1.1 screener, a six-item questionnaire co-developed by the World Health Organization and a Harvard research team, which is one of the most widely used screening measures for adult ADHD in primary care settings. From a product perspective, the build is elegantly simple: a short questionnaire flows into an instant Low, Moderate, or Elevated result, and an optional upgrade path opens an AI-generated personalized report. That report layers on real value—an executive-function pattern map, an analysis of overlapping factors such as sleep, stress, anxiety, and burnout, tailored educational strategies, and a clinician discussion guide with PDF export. The design respects the user's time and intelligence. There is no sign-up wall before the basic result, and the educational framing is consistent throughout: the tool is explicitly a self-screening aid, not a diagnosis. This kind of clear, evidence-aligned positioning is what separates a responsible health utility from a clickbait quiz. For makers browsing a showcase, ADHD Test is a strong example of a single-purpose product done well. It pairs a validated instrument with modern AI assistance in a way that genuinely extends the screener's usefulness, proving that a tight scope and good source material can produce something far more valuable than a bloated all-in-one app.

Explore AppFree PSL Rating runs entirely in your browser for an instant, private AI PSL score with no signup.
Free PSL Rating Free PSL Rating is a browser-based AI tool that analyzes a single uploaded face photo and returns an instant attractiveness estimate on the PSL 1-8 scale, with all processing happening directly in the user's browser. Unlike services that send images to a remote server, Free PSL Rating keeps everything client-side, which means no uploaded photo is ever stored, addressing one of the biggest concerns people have about face-rating tools. The result is a fast, private, and signup-free experience for anyone curious about the PSL framework. To use Free PSL Rating, a person uploads one clear, front-facing photo in JPG, PNG, or WebP format up to 10MB. AI models loaded in the browser then examine visible facial structure and photo quality, generating an overall PSL score, a tier label, and a plain-English explanation of what the number means. The tool also produces a photo confidence score that indicates how reliable the rating is based on image quality, helping users judge whether their result reflects their actual features or the limitations of the photo. Free PSL Rating stands out by breaking the single score into four meaningful categories: harmony, covering symmetry and proportions; dimorphism, reflecting sex-typical structural cues; angularity, capturing jawline, cheekbones, and facial edges; and presentation, accounting for lighting, sharpness, skin clarity, and grooming. Users also receive a shareable result card displaying their overall score, tier, and category scores. With more than 12,800 free ratings run and an average score of 5.4, the platform has built a steady community. A paid advanced report is available through PSL Scale for deeper analysis, but the free tier delivers a complete, private, and instant PSL assessment.
