Privacy-first AI Designed around on-device analysis, ideal for sensitive portraits, artwork, and personal memories.
Delightful presentation Dark, high-contrast UI with tactile scoring, winner badges, and social mockups.

Built Around Real Decisions

SnapScore is not just a score screen. It explains visual quality, compares similar shots, and previews where each image will actually be used.

🎨

Artwork Feedback

Grades line clarity, contrast, balance, and capture quality so artists can photograph sketches and paintings with more confidence.

👤

Social Fit Preview

Shows how portraits and memories look inside LinkedIn, Slack, WhatsApp, Instagram, Facebook, covers, and story-style layouts.

🏆

Winner Selection

Compares similar images, highlights the best option, and gives practical diagnosis instead of leaving users to guess from a gallery grid.

Solving Real-World Problems

How SnapScore turns complex on-device computer vision into simple daily workflows for students, artists, and creators.

Productivity Helper

Notebook Scans & Document Clarity

Scenario: You're a student capturing chalkboard notes or handwritten textbook formulas. Are they clear enough for studying later?

🔍 Text Readability: Analyzes edge clarity and OCR legibility of text characters. 🚨 Highlight Unreadable: Flags blurry, out-of-focus, or skewed document sections. 🗑️ Delete Bad Photos: Instantly wipe low-scoring temp images to save mobile space.

Math: f(x) = ∫(3x² + 2x) dx ✓ Readable
f(x) = x³ + x² + C ⚠️ Blurry
Physics Formula: E = mc² ✓ Readable
Creative Feedback

Artwork Scorer & Composition Critic

Scenario: You're an artist capturing physical charcoal sketches, watercolor paintings, or cartoons. Is the photo high-quality?

✏️ Line & Stroke Clarity: Checks edge gradients using Laplacian filters. 🌓 Value & Contrast Range: Evaluates shading depth and highlight definition. ⚖️ Symmetry & Balance: Scans regional density of stroke structures between left/right halves.

Excellent stroke definition! Shading contrast is good. Center framing is well balanced. Lay the capture sheet completely flat next time to avoid slight perspective warping.
