Your dick,
scientifically.

Upload a photo and our AI computer-vision pipeline (114M parameters, trained on thousands of anonymized specimens) returns a full case file in about 6 seconds. The pipeline measures length, girth, curve, straightness, and shape across anatomy zones and visual attributes. The output is a composite score from 0–100, an archetype classification, and a percentile against the cohort. Not a ChatGPT wrapper — real CV with sub-pixel measurement precision.

Sub-pixel measurement precision against ground-truth annotations. The model uses a proprietary Computer Vision pipeline as the backbone with a custom measurement output specifically fine-tuned for anatomical analysis. Every analysis reports a confidence score; when conditions reduce accuracy (low-contrast base, partial framing, etc.), the report surfaces a quality flag and recommends a retake. The thousands of specimens in the training cohort are large enough that population-level statistics are stable, so your percentile reflects a real reference distribution rather than a guess.

Yes. Uploads are encrypted in transit (TLS 1.3) and stored encrypted at rest. Photos auto-purge from our servers after 60 minutes unless you unlock the full case file. We never share, sell, or use your photo to train any model. No facial recognition is performed. Anonymous analyses aren't tied to any account or personally identifying information. Full details are in the privacy policy.

60 minutes by default for free anonymous analyses, then auto-purged. If you unlock the full case file, the photo is retained on your case file so you can revisit your report and apply photo-overlay skins. You can delete the photo at any time from your account dashboard, regardless of unlock status.

Free to upload and see your teaser report (silhouette, archetype, score range, percentile band). $4.99 one-time to unlock the full case file: exact composite score, all five pillar scores with drivers, exact percentile vs the cohort, share card, PDF download, and lifetime access to your report. No subscription, no recurring charges, no hidden fees.

Yes. No account required to run an analysis. We don't ask for your name, age (beyond an 18+ confirmation), or any personally identifying info. Anonymous analyses tie to an ephemeral device session, not to your identity. If you want to save case files across devices, you can create an optional free account at any point — that's the only time we link your reports to an email address.

Skins are a design overlay that can be purchased from the store, or uploaded by you to apply to your specimen. We drop new sets for special occasions and holidays on a monthly basis. If you create an account, you can save multiple and apply them across your uploads.

Among the 5,041-specimen cohort in the RateMyDick.ai system, the median erect length sits in the 5.1–5.5 inch range (13.0–14.0 cm), and median erect girth in the 4.5–4.9 inch range (11.4–12.4 cm). These figures are consistent with the peer-reviewed anatomical literature, notably Veale et al. (2015) which aggregated 15,521 men across 20 studies. Your case file shows exactly where you sit against this distribution as a percentile.

Your percentile is the percentage of the 5,041-specimen cohort that scored at or below your composite score. A 75th percentile means three out of four specimens score lower than yours; a 50th percentile is exactly the median. Percentiles are computed against the same scoring model for every analysis, so they're directly comparable across different users and time periods.

An archetype is a classification of penile morphology based on length-to-girth ratio, curvature, head-to-shaft proportion, and a few subtler geometric features. RateMyDick.ai uses twelve archetypes — The Mushroom, The Tapered, The Pencil, The Anvil, The Cone, and others — and assigns each analysis to the closest match. Archetype is separate from score: a high-scoring Mushroom and a high-scoring Tapered both rank well, just along different geometric axes.
