How it works

From URL to brand pack in one call.

Three steps, one round-trip. The pipeline runs identically for a homepage demo and for a paying API call — same agents, same validator, same brand pack.

  1. 01

    POST a URL

    Single endpoint. Send any public website URL — we handle the rest.

    curl -X POST https://api.brandrna.com/api/v1/analyze \
  -H "Authorization: Bearer bd_..." \
  -d '{"url":"https://stripe.com"}'
  2. 02

    We render and extract

    Headless Chromium loads the page like a real browser, extracts CSS variables, fonts, logos, screenshots, and runs them through a five-agent LLM pipeline with a validator.

  3. 03

    Get a structured brand pack

    JSON: colors with roles, fonts with weights, logos in dark/light/transparent variants, voice + archetype, summary, similar brands, industry palette norms.

Built for

Anyone shipping software that needs to look right.

Landing-page personalisation

Match a visitor's brand on their referring domain — render dynamic hero copy, swap accent colors, mirror their typography. Lift conversion without a designer in the loop.

AI agents and copilots

Give your AI builder the brand vocabulary of any site it's working with. Generate code, copy, or designs that respect the customer's existing identity.

Design ops and brand audits

Pull a brand pack for any URL into Figma, Slack, or your own tooling. Compare brands across a portfolio. Snapshot identity drift over time.
