# Competitor Comparison

> “Us vs them” comparison table: your product in a raised column with its price and call to action beside the alternatives. Grouped rows show yes, partial and no glyphs or short text, with cell notes gathered into numbered footnotes. A Differences only switch hides rows where everyone matches, and on phones a switcher picks which alternative sits beside yours.

## Install

One-time setup (needs a subscription):

1. Add the registry to the project's `components.json`: `{"@assembli":{"url":"https://www.assembli.design/r/{name}.json","headers":{"Authorization":"Bearer ${ASSEMBLI_API_KEY}"}}}` (merge into `"registries"`).
2. Put an API key from https://www.assembli.design/account in `.env.local` as `ASSEMBLI_API_KEY=asm_…`.

Then install with the shadcn CLI (writes `components/competitor-comparison/competitor-comparison.tsx` and installs dependencies):

```bash
npx shadcn@latest add @assembli/competitor-comparison
```

Registry item JSON: https://www.assembli.design/r/competitor-comparison.json (send `Authorization: Bearer <api key>`)
