Brand Kit - Brand Extraction and Design System Template

Brand Kit takes a URL or a handful of brand files and turns them into a structured design system you can browse, edit, and hand off. Paste a company's site, drop in screenshots, PDFs, or logos, and the app reads the source for palette, typography, marks, and voice.

Each kit includes color swatches with contrast scoring, font families with live previews, logo and asset variants, a tone-of-voice summary, and a set of inferred design tokens. An inspector lets you rename, edit, or remove anything that didn't come through cleanly, and a library view keeps every kit you've built in one place.

When a kit is ready, export it as a branded PDF guide, a complete ZIP with assets and font files, design tokens JSON, a Tailwind theme, or a design.md you can drop straight into an AI coding agent. Each kit can also be shared via a public link without requiring viewers to sign in.

Authentication is optional — you can build kits anonymously and the app remembers them on your device, or sign in to sync your library across browsers.

Who this is for

Designers and brand strategists auditing competitors or onboarding new client brands

Product teams who need a shared source of truth for colors, type, and voice

Founders preparing pitch decks, landing pages, or rebrands and need reference systems fast

Builders feeding brand context to AI coding agents and want a clean design.md to paste in

Best use cases

Competitive and reference audits

Drop in a list of competitor or inspiration URLs and get a side-by-side library of palettes, typography, and voice. The library view makes it easy to scan dozens of brands without juggling tabs.

Client onboarding for agencies

When a new client arrives with only a website, build their brand kit in a single pass. Share the resulting kit link with your team so designers, writers, and developers all work from the same source.

Pitch decks and rebrands

Pull a structured kit for any brand you're presenting about or rebuilding. Export the brand guide PDF for stakeholders, or the tokens and Tailwind theme for the team actually shipping the work.

Seeding AI agents with brand context

Export design.md and the ZIP of fonts and assets, then drop them into Lovable or another AI agent so the next thing it builds matches the brand from the first prompt.

Getting started

Step 1: Remix this template

Click "Remix" to create your copy. You'll get a working brand extractor you can try on any URL before adjusting anything.

Step 2: Customize your brand

Update the washi-and-ink palette, swap the editorial typography, and rename the app to match your own product. The design system lives in src/styles.css and DESIGN.md.

Step 3: Add your own brands and sources

Open the home page, paste a URL, or drop logos and PDFs. Each successful run becomes a kit in the library that you can rename, edit, duplicate, or delete.

Step 4: Invite your team

Share individual kits with a public link, or sign in so your library follows you across devices. Use the same flow to pass kits to designers, copywriters, or AI agents.

Step 5: Go live

Deploy with one click and share the URL with your team or clients. Lovable handles hosting and performance.

Step 6: Iterate and make it yours

Adjust the extraction prompts, export formats, or kit layout to match how your team works. Everything from the ingestion panel to the brand guide PDF is yours to tune.

Conclusion

Brand Kit is for designers, brand strategists, and product teams who keep rebuilding the same "what does their brand actually look like?" document from scratch. You get URL and file ingestion, automatic palette and typography extraction, logo and asset capture, a voice summary, and a full set of exports — PDF, ZIP, tokens, Tailwind theme, and design.md — in a template you can deploy in minutes. Whether you're prepping a pitch, onboarding a new client, or seeding an AI agent with a brand's identity, the kit replaces the folder of screenshots you've been emailing around.
