AI-ready brand intelligence

Every website has
a visual DNA.

Fingerprint extracts it — colors, typography, voice, imagery style — and translates it into AI system prompts that keep every generated artifact on-brand.

How it works
01

Paste any URL

Your site, a competitor's, a client's — Fingerprint reads the live CSS, computed styles, and content to build a complete picture.

02

Extract brand signals

Colors at scale. Typography hierarchy. Imagery mood. Copy tone. Spacing rhythm. Nothing is approximated — every token is sourced from the live site.

03

Get AI-ready output

Structured JSON design tokens + a system prompt template. Drop it into your AI agents and every output respects the brand — no drift, no generic defaults.

What you get

Color Tokens

Primary, secondary, neutral, accent — with hex, OKLCH, and CSS variable output. Scaled at 10 lightness steps each.

Typography System

Display, heading, body, caption — each with exact font family, size, weight, line-height, and letter-spacing. Google Fonts paired automatically.

Brand Voice

Analysis of copy tone, sentence structure, vocabulary register, and emotional register — distilled into a usage guide your AI can apply.

Imagery Style

Color temperature, contrast ratio, saturation bias, and composition patterns — guidance for generating or sourcing on-brand visuals.

The output

Ready for your AI stack on day one

Fingerprint doesn't give you a PDF. It gives you structured data your AI agents can actually consume.

Why Fingerprint

Other tools extract.
Fingerprint integrates.

Extraction tools

Visual DNA, Zoviz, HubSpot — they give you colors and fonts. Useful for designers. Dead end for AI.

Fingerprint closes the gap
AI-ready output

Structured prompts + design tokens + voice guidelines. The output goes directly into your AI agents, vibe coding tools, and automated content pipelines.

Your brand is already defined.
Now your AI can read it.

Stop letting AI generate artifacts that look nothing like your brand. Fingerprint makes every AI tool brand-aware, starting from a single URL.
